Product details
Overview
SMCJ160AHM3_A/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 (VWM), 259 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It protects MOSFETs, ICs, and sensor signal lines in automotive power systems and industrial motor drives.
For engineers reviewing the SMCJ160AHM3_A/I datasheet, SMCJ160AHM3_A/I pinout, SMCJ160AHM3_A/I application, or SMCJ160AHM3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 75 °C/W), and junction temperature range (–55 °C to +150 °C).
Technical Context
This TVS diode operates as a clamping device that diverts transient energy away from sensitive downstream circuitry using an avalanche breakdown mechanism. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under 10/1000 µs surge waveforms.
The SMCJ160AHM3_A/I features bidirectional-capable construction (though configured unidirectional per marking), meets MSL Level 1 per J-STD-020, and supports automated placement due to its low-profile SMC package with matte tin-plated leads solderable per J-STD-002.
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 test current, ensuring predictable turn-on |
| VC @ IPPM | 259 V - Clamped voltage seen by protected circuit during 5.8 A 10/1000 µs surge |
| PPPM | 1500 W - Peak surge power handling capability under standardized waveform |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on standard 8 mm × 8 mm copper pads |
| Package | SMC (DO-214AB) - Surface-mount outline with cathode band marking and 0.320" body length |
Pinout & Package
SMCJ160AHM3_A/I uses the industry-standard SMC (DO-214AB) package: a rectangular surface-mount case measuring 7.11 mm × 6.22 mm × 2.62 mm, with matte tin-plated leads and cathode band marking on the anode side. Polarity is unidirectional; the banded end is the cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when V > VBR |
| Anode (unmarked end) | Reference node | Typically tied to system ground or low-impedance return path for clamping action |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power rails |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for modern industrial and consumer electronics |
| Low incremental surge resistance | Enables tighter clamping and lower let-through voltage during fast transients |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility up to 260 °C peak temperature |
| Glass passivated junction | Provides stable, repeatable breakdown characteristics over temperature and lifetime |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160AHE3_A/I | Lower PPPM (400 W), smaller SMA package, same VWM and VC | Not suitable for high-energy surges; limited to low-power signal lines | Select only where space constraints outweigh surge energy requirements |
| SMCJ160AHE3_A/I | Same electrical specs but non-halogen-free; lacks HM3 suffix compliance | Acceptable for commercial-grade designs without halogen-free mandates | Choose when cost sensitivity overrides environmental compliance needs |
Compared with SMCJ160AHM3_A/I, SMAJ160AHE3_A/I offers reduced surge capacity in a smaller footprint, while SMCJ160AHE3_A/I matches performance but omits halogen-free certification-making the HM3 variant optimal for automotive and green-industrial deployments requiring full regulatory alignment.

FAQ
What is the clamping voltage of the SMCJ160AHM3_A/I under a 10/1000 µs surge?
The SMCJ160AHM3_A/I clamps to a maximum of 259 V when subjected to its rated 5.8 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the SMCJ160AHM3_A/I AEC-Q101 qualified?
Yes, the SMCJ160AHM3_A/I carries AEC-Q101 qualification, confirmed by Vishay's ordering code suffix "HM3" and documentation in the SMCJ5.0A–SMCJ188CA datasheet (Document Number 88394, Revision 09-Jan-2024). This validates its suitability for automotive electronic control units and powertrain modules.
What does the "HM3" suffix indicate in SMCJ160AHM3_A/I?
The "HM3" suffix in SMCJ160AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade "M3" or "E3" versions and confirms compliance with automotive environmental and reliability standards.
Can SMCJ160AHM3_A/I be used in bidirectional configurations?
No, SMCJ160AHM3_A/I is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix and cathode band marking. For bidirectional operation, Vishay specifies part numbers ending in "CA", such as SMCJ160CA, which have symmetrical breakdown in both directions.
What is the thermal resistance of SMCJ160AHM3_A/I, and how does it affect layout?
The SMCJ160AHM3_A/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 safe junction temperatures under repeated surges, PCB layout must provide adequate copper area and avoid thermal bottlenecks near the device.
