Product details
Overview
1.5SMC160AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the 1.5SMC160AHM3_A/I datasheet, 1.5SMC160AHM3_A/I pinout, 1.5SMC160AHM3_A/I application, or 1.5SMC160AHM3_A/I equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, SMC (DO-214AB) package thermal resistance, and unidirectional polarity marking for correct PCB orientation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (179–189 V), it avalanches to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low leakage (<1 μA at 136 V), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device delivers 1500 W peak pulse power handling with <1 ns response time and low incremental surge resistance - critical for suppressing lightning-induced surges (IEC 61000-4-5) and inductive switching transients in 12 V/24 V automotive and industrial systems. Thermal resistance (RθJA = 75 °C/W) is specified on 8.0 mm × 8.0 mm copper pads per terminal.
Key Specifications

|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC/AC operating margin. |
| VBR (Breakdown Voltage) | 179–189 V at 1 mA - Confirmed avalanche initiation range; ensures reliable triggering above system nominal voltage. |
| VC (Clamping Voltage) | 219 V at IPPM = 6.8 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream ICs/MOSFETs. |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for standardized 10/1000 μs waveform; validates compliance with IEC 61000-4-5 Level 4. |

| AEC-Q101 Qualified | Yes - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; suffix HM3 denotes halogen-free RoHS-compliant version. |
| Operating Temperature | −65 °C to +150 °C - Full junction temperature range enables use in under-hood and industrial environments without derating. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; cathode indicated by band on one end; polarity-critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential side of protected line; must be routed to ground or return path in clamping configuration. |
| Cathode | Current exit point during reverse avalanche | Banded terminal; connects to protected line (e.g., 12 V rail or CAN_H); defines directionality and clamping reference. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables single-device protection against severe transients like ISO 7637-2 Pulse 5a without cascaded TVS stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 | Lower PPPM (600 W), SMB package (smaller thermal mass), higher RθJA (110 °C/W) | Not rated for AEC-Q101; suitable only for commercial-grade consumer/industrial use | Select when space-constrained layouts preclude SMC footprint and surge energy is ≤600 W. |
| 1.5KE160A | Through-hole DO-201 package, same VWM/VC specs, but no AEC-Q101 or MSL Level 1 rating | Limited to non-automotive, non-reflow production; incompatible with automated SMT lines | Choose for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ160A-E3/52 and 1.5KE160A, the 1.5SMC160AHM3_A/I uniquely combines AEC-Q101 qualification, 1500 W surge capability in SMC form factor, and halogen-free RoHS compliance - making it the only option qualified for volume automotive SMT production with full IEC 61000-4-5 Level 4 coverage.

FAQ
What is the clamping voltage of the 1.5SMC160AHM3_A/I under a 10/1000 μs surge?
The 1.5SMC160AHM3_A/I has a maximum clamping voltage (VC) of 219 V at a peak pulse current (IPPM) of 6.8 A with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC160AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC160AHM3_A/I qualified for automotive applications?
Yes, the 1.5SMC160AHM3_A/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 1.5SMC Series datasheet (Document Number: 88303). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD - validating suitability for engine control units, body electronics, and ADAS power domains. The 1.5SMC160AHM3_A/I is explicitly listed among AEC-Q101 variants in the ordering table.
What does the "HM3" suffix indicate in 1.5SMC160AHM3_A/I?
The "HM3" suffix in 1.5SMC160AHM3_A/I denotes a halogen-free, RoHS-compliant, and AEC-Q101-qualified version with matte tin-plated leads. Per Vishay's ordering information, HM3 devices meet JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability standards. The "_A/I" further specifies packaging in 13-inch tape-and-reel (3500 units) with revision code A. The 1.5SMC160AHM3_A/I is not a commercial-grade variant - it is fully automotive-qualified.
How does the 1.5SMC160AHM3_A/I compare to bidirectional TVS diodes?
The 1.5SMC160AHM3_A/I is unidirectional and intended for DC line protection where polarity is fixed - such as 12 V battery inputs or regulated power rails. Unlike bidirectional types (e.g., 1.5SMC160CA), it conducts only in reverse avalanche and blocks forward current up to 3.5 V at 100 A. Its cathode band provides clear PCB orientation guidance, and it offers tighter VBR tolerance and lower leakage than equivalent bidirectional parts. For AC or differential-signal protection, a bidirectional variant would be required instead of the 1.5SMC160AHM3_A/I.
What is the thermal resistance of the 1.5SMC160AHM3_A/I, and how does it affect layout?
The 1.5SMC160AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. This value assumes standard JEDEC test conditions and directly impacts power derating: at 100 °C ambient, its 6.5 W steady-state dissipation drops to ~3.3 W. Layout must replicate the specified pad area and avoid thermal isolation - undersized pads or lack of internal ground planes will raise actual RθJA and risk thermal runaway during repetitive surges. The 1.5SMC160AHM3_A/I datasheet provides exact pad dimensions in inches/mm for verification.
