Product details
Overview
SMCJ160AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 160 V standoff voltage, 259 V clamping voltage at 5.8 A peak pulse current, and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive power systems and industrial motor drives.
For engineers reviewing the SMCJ160AHM3/I datasheet, SMCJ160AHM3/I pinout, SMCJ160AHM3/I application, or SMCJ160AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, halogen-free RoHS compliance, and thermal resistance of 75 °C/W junction-to-ambient under standard pad layout.
Technical Context
This TVS diode operates as a clamping device that enters avalanche breakdown above its 178–197 V breakdown voltage range (at 1 mA test current), limiting transient overvoltages to ≤259 V while absorbing up to 1500 W of 10/1000 μs waveform energy. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns).
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 6.5 W steady-state power dissipation at 50 °C ambient and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101 qualified construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 178 V / 197 V - breakdown occurs within this range at 1 mA, defining turn-on threshold |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160AHE3/A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Suitable only for lower-energy transients; not recommended for automotive load dump | Select when space-constrained and surge energy is limited to ≤400 W |
| 1.5KE160A | Through-hole DO-201 package, same VWM/VC specs but higher mounting thermal resistance | Requires wave soldering or hand assembly; incompatible with fully SMT production lines | Choose only for legacy through-hole designs or prototyping where rework tolerance is prioritized |
Compared with SMCJ160AHM3/I, SMAJ160AHE3/A offers reduced surge handling and thermal performance due to smaller package size, while 1.5KE160A sacrifices automated assembly compatibility for identical electrical clamping behavior in through-hole layouts.

FAQ
What is the clamping voltage of SMCJ160AHM3/I under a 10/1000 μs surge?
The SMCJ160AHM3/I clamps to a maximum of 259 V when subjected to its rated peak pulse current of 5.8 A using the standard 10/1000 μs waveform. This value is measured across the device terminals and defines the upper voltage limit imposed on protected circuits during transient events, ensuring downstream components remain within safe operating limits.
Is SMCJ160AHM3/I qualified for automotive use?
Yes, SMCJ160AHM3/I carries the HM3 suffix, indicating it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. This certification validates its suitability for automotive applications including engine control units, body electronics, and ADAS power supplies where reliability under temperature cycling, vibration, and high-energy transients is required.
What does the "HM3" suffix mean in SMCJ160AHM3/I?
The "HM3" suffix in SMCJ160AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade M3 (halogen-free, RoHS, no AEC-Q101) and E3 (RoHS only) versions, confirming compliance with automotive material and reliability standards.
Can SMCJ160AHM3/I be used in bidirectional configurations?
No, SMCJ160AHM3/I is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional operation, Vishay specifies the CA suffix (e.g., SMCJ160CA); using SMCJ160AHM3/I in reverse-biased signal paths would result in forward conduction and failure to suppress negative-going transients.
What is the thermal resistance of SMCJ160AHM3/I and how does it affect layout?
The SMCJ160AHM3/I has 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. To maintain junction temperature below 150 °C under full 6.5 W steady-state dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks-undersized traces or insufficient copper will cause premature thermal shutdown or parametric drift.
