Product details
Overview
SMCJ160A-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 160 V standoff voltage, 178–197 V breakdown range at 1 mA, and 259 V clamping voltage at 5.8 A peak pulse current. It delivers 1500 W peak pulse power handling under 10/1000 μs waveform and operates across -55 °C to +150 °C junction temperature for automotive and industrial power rail protection.
For engineers reviewing the SMCJ160A-M3/57T datasheet, SMCJ160A-M3/57T pinout, SMCJ160A-M3/57T application, or SMCJ160A-M3/57T equivalent, this part supports robust overvoltage protection on DC power inputs, motor drive control lines, and sensor supply rails where fast response (<1 ns), low clamping ratio, and AEC-Q101-compliant reliability are required.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for low incremental surge resistance and stable clamping behavior under repetitive transients. Its unidirectional polarity features a cathode band marking and exhibits 1.0 μA maximum reverse leakage at 160 V standoff, enabling minimal standby power loss in always-on systems.
The device meets J-STD-020 MSL Level 1 moisture sensitivity and withstands 200 A non-repetitive forward surge (8.3 ms half-sine), making it suitable for protecting MOSFET gates, IGBT drivers, and DC-DC converter inputs against load dump and inductive switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VWM) | 160 V - Maximum continuous reverse operating voltage before significant conduction begins; sets upper limit for protected circuit DC bias. |
| Breakdown Voltage (VBR) | 178–197 V at 1 mA - Confirmed voltage range where device transitions from high-impedance to low-impedance clamping state. |
| Clamping Voltage (VC) | 259 V at 5.8 A IPPM - Peak voltage seen by downstream circuit during 1500 W transient; defines worst-case stress on protected ICs. |
| Peak Pulse Power (PPPM) | 1500 W (10/1000 μs) - Energy-handling capability for standardized surge waveforms; validates suitability for ISO 7637-2 Pulse 5a/b load dump events. |
| Junction Temperature Range | -55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor controls, and outdoor power electronics without derating. |
| Package | SMC (DO-214AB) - Surface-mount outline with 8.0 mm × 8.0 mm copper pad thermal footprint; supports automated placement and 260 °C reflow. |
Pinout & Package
SMCJ160A-M3/57T is housed in an SMC (DO-214AB) package with two terminals: anode and cathode. The cathode is marked by a visible band on the body. No internal leads or additional terminals exist.
| Pin/Terminal | Circuit Role | Design Meaning |

| Low incremental surge resistance | Enables tighter clamping voltage tolerance and reduced overshoot during fast-rising transients (e.g., ESD or lightning-induced surges). |
| Halogen-free, RoHS-compliant construction (M3 suffix) | Meets environmental compliance requirements for automotive and industrial OEMs without compromising surge performance. |
| 1500 W peak pulse power rating | Supports protection against severe load-dump transients per ISO 7637-2 in 12 V and 24 V vehicle electrical systems. |
| Fast response time (<1 ns) | Clamps before sensitive downstream components (e.g., microcontrollers or gate drivers) experience damaging overvoltage stress. |
| AEC-Q101 qualification available | Variant SMCJ160AHM3_X meets automotive-grade reliability testing for mission-critical power rail protection. |
Applications
| Automotive Load Dump Protection | Industrial DC Power Input Protection |
|---|---|
Use Scenario: Protecting engine control unit (ECU) 12 V supply against alternator load dump transients up to 120 V for 400 ms. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp surge energy before LDO or DC-DC regulator. Use Value: Limits peak voltage to 259 V during 1500 W transient, preventing latch-up or permanent damage to 36 V-rated input stages. |
Use Scenario: Safeguarding programmable logic controller (PLC) 24 V DC input module from inductive kickback caused by solenoid switching. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected across input terminals to shunt surge current away from signal conditioning circuitry. Use Value: Clamps within nanoseconds to hold voltage below 260 V, preserving integrity of optocoupler isolation barriers and analog front-end ADCs. |
| MOSFET Gate Driver Protection | Sensor Signal Line Protection |
Use Scenario: Shielding high-side N-channel MOSFET gate driver ICs from voltage spikes induced by fast-switching in half-bridge motor drives. IC Role / Device Role / Timing Role: TVS placed between gate and source to suppress dv/dt-induced coupling and Miller-effect overshoot. Use Value: 1.0 μA leakage at 160 V ensures no impact on gate charge/discharge timing; 259 V VC prevents gate oxide breakdown. |
Use Scenario: Securing automotive ambient temperature sensor output (0–5 V analog) against coupled transients from nearby ignition coils or fuel injectors. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS installed at connector interface to absorb EFT and surge energy before signal conditioning amplifier. Use Value: Maintains signal fidelity with sub-pF junction capacitance; clamps transients before they distort 12-bit ADC readings or trigger false fault flags. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160A | Same 160 V VWM, 1500 W PPPM, but SMC package with slightly higher clamping voltage (265 V at 5.7 A) and 2.0 μA ID at VWM. | Valid for general-purpose industrial protection; less suited for low-leakage automotive sensor interfaces due to higher ID. | Select when cost sensitivity outweighs marginal leakage or clamping performance trade-offs in non-automotive designs. |
| ON Semiconductor 1.5SMC160A | Identical VWM (160 V), same SMC package, but lower PPPM (1500 W), higher VC (270 V at 5.6 A), and wider VBR range (178–212 V). | Acceptable for non-critical AC/DC adapter inputs where tighter clamping is not required; not recommended for AEC-Q101 environments. | Choose only if legacy BOM alignment or distributor stock availability drives selection-verify thermal derating curves differ from Vishay's. |
Compared with SMCJ160A-M3/57T, SMAJ160A offers marginally higher leakage and looser clamping, while 1.5SMC160A trades clamping precision and automotive qualification for broader second-source availability-making SMCJ160A-M3/57T optimal for high-reliability 12–24 V power rail protection where leakage, clamping consistency, and thermal stability are critical.

FAQ
What is the maximum clamping voltage of SMCJ160A-M3/57T under standard test conditions?
The SMCJ160A-M3/57T has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current of 5.8 A using a 10/1000 μs waveform. This value is measured per JEDEC standards and reflects worst-case voltage stress imposed on protected circuitry during surge events-critical for validating compatibility with downstream 300 V-rated components.
Does SMCJ160A-M3/57T meet automotive qualification standards?
The base SMCJ160A-M3/57T is commercial-grade and halogen-free/RoHS-compliant, but not AEC-Q101 qualified. However, Vishay offers the automotive variant SMCJ160AHM3_X (with "_X" denoting revision code), which undergoes full AEC-Q101 stress testing and is approved for under-hood automotive applications including engine control and body electronics.
How does the M3 suffix affect the material composition of SMCJ160A-M3/57T?
The M3 suffix on SMCJ160A-M3/57T indicates halogen-free, RoHS-compliant construction meeting IEC 61249-2-21 requirements. Unlike E3-suffix parts, M3 devices eliminate brominated flame retardants and chlorine-based compounds in the molding compound while maintaining identical electrical specs, thermal performance, and UL 94 V-0 flammability rating.
What is the thermal resistance from junction to ambient for SMCJ160A-M3/57T?
The typical thermal resistance from junction to ambient (RθJA) for SMCJ160A-M3/57T is 75 °C/W when mounted on the minimum recommended 8.0 mm × 8.0 mm copper pad layout per JEDEC standards. This value assumes no external heatsinking and guides derating calculations for continuous power dissipation in high-temperature environments.
Can SMCJ160A-M3/57T be used in bidirectional protection circuits?
No-SMCJ160A-M3/57T is strictly unidirectional, indicated by its "A" suffix and cathode band marking. For bidirectional operation, Vishay specifies the SMCJ160CA variant (with "CA" suffix), which provides symmetrical clamping in both polarities and no polarity marking. Using SMCJ160A-M3/57T in AC or reversible DC paths risks catastrophic failure due to forward conduction during negative transients.
