Product details
Overview
SMCJ160AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 259 V at 5.8 A peak pulse current, with 160 V standoff voltage and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive power systems, industrial motor drives, and telecom interfaces.
For engineers reviewing the SMCJ160AHE3_A/H datasheet, SMCJ160AHE3_A/H pinout, SMCJ160AHE3_A/H application, or SMCJ160AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 178–197 V breakdown voltage range at 1 mA, low 0.108 %/°C VBR temperature coefficient, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds its 160 V stand-off level (VWM) and clamping to ≤259 V at 5.8 A (10/1000 μs waveform). Its glass-passivated junction ensures stable breakdown behavior and fast response time under surge conditions.
Designed for high-energy transient suppression, it delivers 1500 W peak pulse power dissipation with low incremental surge resistance and meets MSL Level 1 per J-STD-020 (260 °C reflow peak). The AEC-Q101 qualification confirms suitability for automotive electronics requiring robust reliability across -55 °C to +150 °C operating junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/57T | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Limited to lower-energy transients; unsuitable for automotive load-dump or industrial motor drive scenarios | Select only for space-constrained consumer electronics with <500 W surge requirements |
| SMCJ160CAHE3_A/H | Bidirectional variant; same VWM (160 V), symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur (e.g., audio, USB D+/D-) | Choose when protecting bidirectional data buses or transformer-coupled interfaces |
Compared with SMCJ160AHE3_A/H, SMAJ160A-E3/57T offers reduced board area but sacrifices 73 % peak power handling and thermal robustness, while SMCJ160CAHE3_A/H provides polarity-agnostic clamping at identical energy rating-making it essential for AC or differential signaling where unidirectional bias cannot be guaranteed.

FAQ
What is the breakdown voltage range of the SMCJ160AHE3_A/H?
The SMCJ160AHE3_A/H has a specified breakdown voltage (VBR) range of 178 V to 197 V at a test current of 1 mA, measured per ANSI/IEEE C62.35. This tolerance window ensures reliable turn-on behavior across manufacturing lots and temperature extremes, supporting consistent clamping performance in automotive and industrial deployments where voltage margin is critical.
Is the SMCJ160AHE3_A/H suitable for automotive applications?
Yes, the SMCJ160AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix. It meets stringent requirements for temperature cycling, humidity resistance, and surge endurance, making it appropriate for engine control units, body electronics, and ADAS sensor modules exposed to load-dump transients and conducted emissions per ISO 7637-2.
What is the maximum clamping voltage for the SMCJ160AHE3_A/H under surge conditions?
The SMCJ160AHE3_A/H clamps to a maximum of 259 V when subjected to its rated 5.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage margining in designs using the SMCJ160AHE3_A/H.
Does the SMCJ160AHE3_A/H have polarity marking, and how is it identified?
Yes, the SMCJ160AHE3_A/H is unidirectional and features a visible cathode band on the SMC (DO-214AB) package body. This band identifies the cathode terminal, which must be connected toward the protected line (e.g., power rail or signal trace), while the anode connects to ground or reference potential to establish proper clamping polarity.
What is the thermal resistance profile of the SMCJ160AHE3_A/H?
The SMCJ160AHE3_A/H exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, and a junction-to-lead resistance (RθJL) of 15 °C/W. These values enable effective heat dissipation during repetitive surge events and support sustained operation up to +150 °C junction temperature in thermally constrained enclosures.
