Product details
Overview
SMPC60ANHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMPC (TO-277A) package, designed for high-energy surge protection with 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) at 10/1000 μs. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the SMPC60ANHM3/H datasheet, SMPC60ANHM3/H pinout, SMPC60ANHM3/H application, or SMPC60ANHM3/H equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge, polarity marking convention, and AEC-Q101 qualification status - all critical for robust overvoltage protection design in safety-critical embedded systems.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging silicon p-n junction breakdown to clamp transient overvoltages above its VWM of 60 V while maintaining low leakage (<1.0 μA). Its 96.8 V maximum clamping voltage (VC) at 15.5 A IPPM ensures downstream components remain within safe operating limits during standardized 10/1000 μs surges.
Thermally, it features RθJA ≤ 100 °C/W on FR4 PCB (2 oz copper), enabling reliable operation up to TJ = 150 °C. The cathode band marking and dual-anode/dual-cathode SMPC package configuration support high-current surge paths with low incremental surge resistance - confirmed by its fast response time and MSL Level 1 moisture sensitivity rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines system-level DC rail protection threshold. |

Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed microcontroller power rails in engine control units against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VCC and GND, clamping transients exceeding 60 V before they reach LDO inputs or MCU VDD pins. Use Value: Withstands 1500 W surges and maintains <1.0 μA leakage at 60 V, ensuring no impact on quiescent current or brownout detection thresholds. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in PLC modules exposed to relay coil switching noise. IC Role / Device Role / Timing Role: Connected across sensor output and ground to shunt inductive kickback from nearby solenoid drivers. Use Value: 96.8 V clamping voltage ensures downstream op-amp inputs stay below absolute maximum ratings even during 15.5 A surge events. |
| MOSFET Gate Driver Protection | Telecom Line Card Surge Suppression |
Use Scenario: Shielding high-side N-channel MOSFET gates in half-bridge motor drivers from Miller-induced voltage spikes during switching transitions. IC Role / Device Role / Timing Role: Mounted directly at gate-source terminals to clamp dv/dt-induced overshoot before gate oxide breakdown occurs. Use Value: Sub-nanosecond response and low dynamic impedance limit gate-source voltage excursion to ≤96.8 V, preserving long-term gate reliability. | Use Scenario: Front-end protection of Ethernet PHY interfaces or RS-485 transceivers in outdoor telecom cabinets subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Placed on differential signal pairs (e.g., A/B lines) referenced to local ground to absorb common-mode transients. Use Value: Dual-anode configuration allows symmetrical layout with matched trace lengths, minimizing skew during high-speed transient suppression. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60A-HF | Same VWM (60 V), lower PPPM (400 W), SMA package (higher RθJA ≈ 150 °C/W), non-AEC-Q101. | Limited to consumer/industrial boards where automotive qualification and 1500 W surge headroom are not required. | Select when cost or board space is prioritized over automotive compliance and high-energy surge margin. |
| SMCJ60A | Same VWM (60 V), identical PPPM (1500 W), larger SMC package (2.6 mm height), AEC-Q101 available only in HM3 suffix variants. | Requires more PCB area and may not fit in ultra-thin modules; thermal performance similar but mounting footprint differs. | Choose when existing SMC footprint is standardized and height constraint is relaxed. |
Compared with SMAJ60A-HF and SMCJ60A, SMPC60ANHM3/H uniquely combines AEC-Q101 qualification, 1.1 mm profile, and 1500 W capability in a single compact SMPC package - making it optimal for next-generation automotive ECUs where space, reliability, and surge robustness are co-constrained.

FAQ
What is the clamping voltage of SMPC60ANHM3/H at its rated peak pulse current?
The SMPC60ANHM3/H has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 15.5 A under a 10/1000 μs waveform. This value is measured with the cathode mounted on heatsink per the datasheet test condition and defines the upper voltage limit imposed on protected circuitry during surge events. The SMPC60ANHM3/H maintains this clamping performance across its specified operating temperature range.
Is SMPC60ANHM3/H suitable for automotive applications?
Yes, SMPC60ANHM3/H is AEC-Q101 qualified and explicitly designated for automotive use, as indicated by the "HM3" suffix in its part number. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing. The SMPC60ANHM3/H is commonly deployed in engine control units, body electronics, and ADAS subsystems where transient immunity and long-term reliability are mandatory.
How does the SMPC60ANHM3/H package differ from standard SMA or SMC packages?
The SMPC60ANHM3/H uses the SMPC (TO-277A) package - a three-terminal, dual-anode configuration with 1.1 mm typical height, versus the two-terminal SMA (2.7 mm) and SMC (2.6 mm) packages. Its low profile enables placement in tight spaces, and the dual-anode structure reduces effective dynamic resistance during high-current surges. Unlike SMA/SMC, SMPC60ANHM3/H requires correct orientation of the cathode band and leverages both anode terminals for optimized current sharing.
What is the maximum junction temperature rating for SMPC60ANHM3/H?
The SMPC60ANHM3/H has a maximum junction temperature (TJ max) rating of +150 °C, allowing operation in high-ambient environments such as under-hood automotive locations or enclosed industrial enclosures. This rating is supported by its thermal resistance characteristics: RθJA ≤ 100 °C/W on FR4 with 2 oz copper, and RθJM ≤ 3 °C/W when mounted to a heatsink. Derating curves in the SMPC60ANHM3/H datasheet define safe power dissipation limits above 25 °C ambient.
Does SMPC60ANHM3/H have a defined moisture sensitivity level (MSL)?
Yes, SMPC60ANHM3/H meets MSL Level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This means the device can be stored indefinitely at ambient conditions without baking prior to assembly and withstands standard lead-free reflow profiles without popcorn or delamination risk. The SMPC60ANHM3/H's molding compound also complies with UL 94 V-0 flammability requirements.
