Product details
Overview
SMPC60ANHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) in the TRANSZORB® family, designed for high-energy surge protection on power and signal lines. It features a 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), 96.8 V clamping voltage (VC) at 15.5 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces and MOSFET gate protection.
For engineers reviewing the SMPC60ANHM3/I datasheet, SMPC60ANHM3/I pinout, SMPC60ANHM3/I application, or SMPC60ANHM3/I equivalent, key selection criteria include AEC-Q101 qualification, TO-277A (SMPC) package compatibility, unidirectional clamping behavior, thermal resistance (RθJA ≤ 100 °C/W), and 1.1 mm profile for space-constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging avalanche breakdown to limit transient overvoltages before they damage downstream ICs or discrete components. Its low incremental surge resistance and fast response time ensure effective suppression of ESD, load dump, and inductive switching spikes.
The SMPC60ANHM3/I is qualified to AEC-Q101 and built in the SMPC (TO-277A) package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It supports mounting on FR4 PCB with 2 oz copper, delivering 1.25 W steady-state power dissipation at 25 °C ambient and junction temperature operation up to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 66.7 V / 73.7 V at 1 mA - guaranteed avalanche onset range under standardized test conditions |
| VC @ IPPM | 96.8 V at 15.5 A - clamped voltage during 10/1000 μs surge, defining worst-case stress on protected circuit |
| PPPM | 1500 W - peak transient power handling capability, critical for ISO 7637-2 pulse 5a/b compliance |
| TJ max | +150 °C - enables use in under-hood automotive environments without derating penalties |
| RθJA | ≤100 °C/W - thermal resistance to ambient on standard FR4, informs heatsinking requirements |
| Polarity | Unidirectional - cathode-banded configuration requires correct orientation in series with positive rail |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal configuration with cathode band marking; height ≤1.1 mm; meets UL 94 V-0; AEC-Q101 qualified; RoHS/halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Anode 2 | Secondary anode connection | Second anode terminal - identical polarity to Anode 1; both required for rated PPPM performance |
| Cathode | Clamping output node | Banded terminal; connects to protected line (e.g., 12 V rail); conducts during overvoltage to shunt energy to ground |
Key Features
| Feature | Design Value |
|---|---|

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-E3/5A | DO-214AC package; 600 W PPPM; 100 V VC @ 6.5 A; non-AEC-Q101 | Limited to industrial/commercial use; lower surge rating reduces margin in automotive load dump testing | Select when cost sensitivity outweighs AEC-Q101 requirement and PCB space allows larger footprint |
| 1.5KE60A | DO-201AD axial lead; 1500 W PPPM; 96.8 V VC @ 15.5 A; no AEC-Q101 or MSL-1 rating | Requires through-hole assembly; unsuitable for automated SMT lines or high-vibration environments | Choose only for legacy repair or prototyping where reflow compatibility and vibration resistance are not required |
Compared with SMAJ60A-E3/5A and 1.5KE60A, the SMPC60ANHM3/I delivers identical clamping performance in a smaller, automotive-qualified, surface-mount package - enabling higher reliability in production automotive electronics without layout redesign.

FAQ
What is the clamping voltage of SMPC60ANHM3/I and how is it measured?
The SMPC60ANHM3/I has a maximum clamping voltage (VC) of 96.8 V, measured at 15.5 A peak pulse current (IPPM) using a 10/1000 μs double-exponential waveform per Figure 1 in Vishay document 89116. This value defines the upper voltage limit imposed on the protected circuit during surge events and is validated under standardized JEDEC test conditions.
Is SMPC60ANHM3/I suitable for automotive applications?
Yes, SMPC60ANHM3/I is AEC-Q101 qualified and explicitly listed in Vishay's automotive ordering code (suffix HM3). It meets requirements for under-hood and cabin electronics, including temperature cycling, mechanical shock, and humidity exposure - confirmed in the "MECHANICAL DATA" and "ORDERING INFORMATION" sections of document 89116.
What does the "I" suffix mean in SMPC60ANHM3/I?
The "I" suffix in SMPC60ANHM3/I denotes the preferred package code for 13-inch diameter plastic tape and reel delivery, containing 6500 units per reel. This format supports high-volume SMT assembly lines and is specified in Vishay's ordering information table on page 3 of document 89116.
How does the dual-anode configuration of SMPC60ANHM3/I affect PCB layout?
The SMPC60ANHM3/I uses two anode terminals (Anode 1 and Anode 2) that must be connected together externally - either via shared copper pour or short trace - to achieve full 1500 W PPPM rating. Separating them reduces surge current sharing and degrades clamping performance, as confirmed in the "Note" under "FEATURES" and "MECHANICAL DATA".
Does SMPC60ANHM3/I require heatsinking for 1.25 W steady-state dissipation?
No additional heatsink is required for SMPC60ANHM3/I at its rated 1.25 W steady-state power dissipation (PD) when mounted on a standard FR4 PCB with 2 oz copper and the recommended pad layout. Its RθJA ≤ 100 °C/W ensures junction temperature remains within the 150 °C limit at 25 °C ambient, per thermal characteristics in document 89116.
