Übersicht

Description

The SMCJ170A is a unidirectional surface‑mount transient voltage suppressor (TVS) diode in a DO-214AB (SMC) package. It protects high‑voltage DC lines from voltage transients and ESD by remaining non‑conductive up to its standoff level (~170 V) and then avalanching to clamp surges to a safe level. It can absorb high‑energy pulses (peak pulse power in the kilowatt class for brief durations). Typical applications include protecting power‑supply inputs, telecom and automotive/high‑voltage lines. The “A” suffix denotes unidirectional operation; for bidirectional use, a different SMCJ part is used. For design, choose a part with a standoff voltage at or above your maximum operating voltage, and ensure the supply and fuse can tolerate surge events. Always consult the vendor datasheet for exact V_R, V_BR, V_CL, IPP, and footprint recommendations.

Features

Here are the typical features of the SMCJ170A TVS diode:
- Type: Surface-mount transient voltage suppressor (TVS) diode in the SMCJ package.
- Stand-off voltage (VRWM): 170 V.
- Peak pulse power: ~1,500 W (10/1000 µs waveform).
- Fast transient protection: response time in the sub-nanosecond to nanosecond range.
- Clamping: clamps high-energy surges to protect downstream circuitry; designed for IEC 61000-4-5/4-2 type transients.
- Leakage: very low leakage current under normal operation.
- Operating temperature: wide range, typically -55°C to +150°C.
- Construction: silicon avalanche diode, epoxy-molded, rugged and mechanically robust.
- Compliance: RoHS compliant (lead-free).
- Applications: power-supply and DC-bus protection, telecom, automotive, industrial control, and any 170 V rail surge protection.
Note: Exact values for VBR (breakdown), VCL (clamp), and temperature/rating tolerances are specified in the datasheet for the specific lot; refer to it for precise limits.

Package

SMCJ170A is in the SMC (DO-214AB) surface-mount package.

Pinout

- Pin count: 2 terminals (anode and cathode) in the SMC/DO-214AB package.
- Function: Transient Voltage Suppressor (TVS) diode used for surge/ESD protection by clamping overvoltage to protect downstream circuitry.

Manufacturer

Manufacturer: Littelfuse, Inc.
Company type: Littelfuse is a global electronics components company that designs and manufactures circuit protection products, including fuses, TVS diodes (like the SMCJ170A), polyswitches, and related protection solutions.

Application

SMCJ170A is a high‑power TVS diode (SMCJ package) with about 170 V stand‑off, used to clamp transient surges on power rails and lines up to ~170 V. Typical applications: surge/ESD protection for AC mains interfaces (120 VAC line, 170 Vpeak), DC bus protection in power supplies and telecom/data equipment, protection on industrial control and consumer electronics input stages, and line/signal protection in high‑voltage or high‑energy environments.

Equivalent

SMCJ170A is a 170 V standoff TVS diode in the SMC (DO-214AB) package (~1 kW peak pulse). Equivalents are other 170 V TVS diodes in the same packaging from major vendors (e.g., Vishay, Littelfuse, Bourns, ON Semiconductor, Nexperia). For exact cross-reference, please specify whether you need unidirectional vs bidirectional and packaging (SMC vs SMA or axial).
