Product details
Overview
1.5SMC160A-M3/57T 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 1500 W peak pulse power (10/1000 μs), 136 V standoff voltage (VWM), and 219 V clamping voltage (VC) at 6.8 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against lightning-induced transients and inductive switching spikes in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC160A-M3/57T datasheet, 1.5SMC160A-M3/57T pinout, 1.5SMC160A-M3/57T application, or 1.5SMC160A-M3/57T equivalent, this page delivers verified electrical parameters, thermal resistance (RθJA = 75 °C/W), AEC-Q101 qualification status, halogen-free RoHS compliance, and real-world clamping behavior under repetitive 0.01% duty cycle surges.
Technical Context
The 1.5SMC160A-M3/57T operates as a unidirectional avalanche diode with glass-passivated junction, enabling fast response time (<1 ns) and low incremental surge resistance. Its breakdown voltage (VBR) is specified at 152–168 V (IT = 1.0 mA), and it maintains stable clamping performance up to TJ = 150 °C with derating per Figure 2.
Mounted on 8.0 mm × 8.0 mm copper pads, it achieves 1500 W peak pulse power per 10/1000 μs waveform and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). Polarity is marked by cathode band; terminals are matte tin-plated and compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown) | 152–168 V @ 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events |
| VC (Clamping) | 219 V @ IPPM = 6.8 A - Peak voltage seen by protected circuit during full-rated 1500 W transient |
| PPPM | 1500 W - Sustains 10/1000 μs surge pulses at 0.01% duty cycle without degradation |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8 mm × 8 mm pads; informs heatsinking requirements |
| IFSM | 200 A - Withstands single 8.3 ms half-sine surge, critical for motor drive and relay coil suppression |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to system ground or low-side reference | Provides return path during surge conduction; must be routed with low-inductance trace to minimize VL overshoot |
| Cathode | Current exit terminal in forward bias; marked by band; connects to protected line | Defines polarity-sensitive placement-reverse connection disables protection; ties directly to I/O or power rail needing clamping |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Handles high-energy transients (e.g., ISO 7637-2 Pulse 5a) without failure in automotive ECUs and industrial PLCs |
| Glass passivated chip junction | Ensures long-term reliability and stable VBR drift < ±5% over lifetime under thermal cycling |
| AEC-Q101 qualified (M3 suffix) | Validated for automotive applications including engine control, ADAS sensors, and body electronics |
| Low incremental surge resistance | Minimizes VC rise under high di/dt events-critical for protecting fast-switching SiC/GaN gate drivers |
| Matte tin-plated leads | Guarantees robust solder joint integrity per J-STD-002; eliminates whisker risk per JESD 201 Class 2 |
Applications

|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed microcontroller power rails from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND, conducting only during negative-going transients.

| MOSFET Gate Driver Protection | Telecom DC Power Input Stage |
|
Use Scenario: Safeguarding high-side N-channel MOSFET gates in motor inverters against Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Fast-response TVS tied between gate and source, triggered by dV/dt exceeding VBR. Use Value: Sub-1 ns response prevents gate oxide rupture; 219 V clamping avoids exceeding VGS(max) of 25 V–30 V devices. |
Use Scenario: Front-end surge suppression on -48 V telecom rectifier outputs exposed to lightning-induced surges on long feeder lines. IC Role / Device Role / Timing Role: Primary unidirectional clamp on DC bus, coordinated with upstream MOVs and fuses. Use Value: Delivers 1500 W dissipation without thermal runaway; RθJA = 75 °C/W allows natural convection cooling in dense chassis layouts. |
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 footprint), higher VC (259 V @ 2.3 A) | Suitable for space-constrained consumer electronics; insufficient for automotive load dump per ISO 7637-2 | Select when board area is critical and surge energy ≤600 W; verify clamping margin against protected device VDS(max) |
| 1.5KE160A-T | Through-hole DO-201 package, identical VBR/VC, but lower thermal mass and no AEC-Q101 qualification | Used in legacy industrial power supplies where reworkability and manual assembly are prioritized | Choose for prototyping or low-volume production where automated SMT is unavailable; avoid in automotive or high-reliability deployments |
Compared with SMBJ160A-E3/52 and 1.5KE160A-T, the 1.5SMC160A-M3/57T uniquely combines AEC-Q101 qualification, 1500 W rating, and SMC surface-mount compatibility-enabling direct integration into automotive-grade PCBs without layout compromise or derating penalties.

FAQ
What is the maximum clamping voltage of the 1.5SMC160A-M3/57T under rated surge conditions?
The 1.5SMC160A-M3/57T exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 6.8 A (10/1000 μs waveform). This value is measured per Figure 1 in Vishay document 88303 and defines the upper voltage limit imposed on the protected circuit during worst-case transient events. The 1.5SMC160A-M3/57T maintains this clamping performance across its operational temperature range and after repeated surge exposure.
Is the 1.5SMC160A-M3/57T qualified for automotive applications?
Yes, the 1.5SMC160A-M3/57T carries the M3 suffix, indicating halogen-free, RoHS-compliant construction and AEC-Q101 qualification per Vishay's ordering matrix. It is validated for use in automotive subsystems including body control modules, infotainment power supplies, and ADAS sensor interfaces where compliance with load dump (ISO 7637-2) and ESD (ISO 10605) standards is mandatory. The 1.5SMC160A-M3/57T meets these requirements without derating.
What is the standoff voltage (VWM) of the 1.5SMC160A-M3/57T, and how does it relate to system operating voltage?
The 1.5SMC160A-M3/57T has a standoff voltage (VWM) of 136 V, meaning it remains non-conductive up to this reverse DC or peak AC voltage. For reliable operation, system nominal voltage (e.g., 24 V or 48 V DC bus) must remain well below 136 V-typically with ≥20% margin-to prevent leakage current increase or premature conduction. The 1.5SMC160A-M3/57T is therefore suited for 100 V-class systems such as telecom rectifiers or industrial 24 V/48 V supplies.
Does the 1.5SMC160A-M3/57T require a heatsink in typical applications?
No external heatsink is required for the 1.5SMC160A-M3/57T under normal surge conditions, as its thermal design relies on PCB copper pad area (minimum 8.0 mm × 8.0 mm per terminal) to dissipate energy. With RθJA = 75 °C/W and PD = 6.5 W at TA = 50 °C, it operates safely in still air when mounted per Vishay's recommended pad layout. The 1.5SMC160A-M3/57T's SMC package inherently provides sufficient thermal coupling to the board without added mechanical complexity.
How does the 1.5SMC160A-M3/57T differ from bidirectional variants like 1.5SMC160CA-M3/57T?
The 1.5SMC160A-M3/57T is unidirectional and features a cathode band for polarity-specific placement, conducting only during reverse-biased overvoltage events. In contrast, the 1.5SMC160CA-M3/57T is bidirectional with symmetrical clamping in both directions and no polarity marking. The 1.5SMC160A-M3/57T offers lower leakage and tighter VBR tolerance for DC-coupled protection, whereas the CA variant suits AC signal lines or floating buses where polarity is undefined.
