Product details
Overview
TPC13CAHM3/I from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for automotive-grade circuit protection. It features a standoff voltage of 11.1 V, breakdown voltage range 12.4–13.7 V at 1 mA, clamping voltage of 18.2 V at 82.4 A, and operates from −65 °C to +185 °C. It protects MOSFETs and sensor signal lines against inductive switching transients.
For engineers reviewing the TPC13CAHM3/I datasheet, TPC13CAHM3/I pinout, TPC13CAHM3/I application, or TPC13CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 185 °C junction rating, low-profile 1.1 mm height, and compatibility with automated SMT placement on automotive PCBs.
Technical Context
The TPC13CAHM3/I implements a junction-passivated PAR® structure optimized for fast response (<1 ns) and stable clamping under repetitive surge conditions. Its bidirectional architecture enables symmetrical protection without polarity concerns, and its 1500 W peak pulse power rating (10/1000 μs waveform) supports robust immunity to load-dump and ISO 7637-2 pulses.
Designed for high-reliability automotive environments, the device meets MSL Level 1 per J-STD-020, withstands 260 °C lead-free reflow, and passes JESD201 Class 2 whisker testing. The SMPC package provides low thermal resistance and mechanical stability under thermal cycling typical of engine bay and ADAS module deployments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-E3/57T | Unidirectional; 12 V VWM; SMA package; 400 W PPPM | Limited to DC-biased lines; lower surge rating; less suitable for automotive load-dump | Select only for cost-sensitive non-automotive designs where unidirectional protection suffices |
| TPC12CAHM3/I | 10.2 V VWM; 11.4–12.6 V VBR; same SMPC package and AEC-Q101 qualification | Better suited for 9–10 V nominal systems; slightly lower clamping (16.7 V) | Choose when tighter VWM margin is required below 11.1 V, with identical layout and qualification |
Compared with SMAJ12A-E3/57T, the TPC13CAHM3/I delivers 275% higher surge power and automotive qualification; compared with TPC12CAHM3/I, it offers higher VWM headroom for 12 V systems while maintaining identical footprint and thermal performance.

FAQ
What is the clamping voltage of the TPC13CAHM3/I and how is it measured?
The TPC13CAHM3/I has a maximum clamping voltage (VC) of 18.2 V, measured at a peak pulse current (IPPM) of 82.4 A using a 10/1000 μs waveform. This value reflects the voltage across the device during worst-case surge conditions and is critical for ensuring downstream components remain within safe operating limits. The TPC13CAHM3/I achieves this clamping performance while maintaining low leakage and high temperature resilience.
Is the TPC13CAHM3/I suitable for automotive applications?
Yes, the TPC13CAHM3/I is AEC-Q101 qualified, rated for junction temperatures up to +185 °C, and meets MSL Level 1 and JESD201 Class 2 whisker requirements. Its SMPC package and bidirectional architecture make it ideal for protecting 12 V automotive subsystems such as body control modules, ADAS sensors, and infotainment interfaces. The TPC13CAHM3/I is explicitly designated for automotive use via its HM3 suffix.
What does the "HM3" suffix mean in TPC13CAHM3/I?
"HM3" denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101-qualified variant in the TPCxxCA series. It specifies matte tin-plated terminals, JESD201 Class 2 whisker resistance, and compliance with automotive material standards. The "I" indicates 13-inch tape-and-reel packaging (6500 units per reel), distinguishing it from the "H" (7-inch reel) variant. The TPC13CAHM3/I fully retains all electrical and thermal specifications of the base TPC13CA.
How does the TPC13CAHM3/I compare to unidirectional TVS diodes like SMAJ12A?
The TPC13CAHM3/I is bidirectional with symmetric clamping, making it suitable for AC-coupled or floating signal lines, whereas SMAJ12A is unidirectional and requires correct polarity orientation. The TPC13CAHM3/I also delivers 1500 W peak power versus 400 W for SMAJ12A, and is AEC-Q101 qualified-features absent in the SMAJ series. For automotive signal protection, the TPC13CAHM3/I provides superior robustness and design flexibility.
What is the thermal resistance and mounting guidance for the TPC13CAHM3/I?
The TPC13CAHM3/I uses the SMPC (TO-277A) package with JEDEC-compliant pad layout dimensions provided in Vishay document 87649. While specific RθJA is not published, its 1.1 mm profile and copper strap construction enable effective heat dissipation into PCB copper. Recommended mounting follows J-STD-020 reflow profiles with peak temperature ≤260 °C. Thermal performance is validated across −65 °C to +185 °C, and the TPC13CAHM3/I requires no derating up to +125 °C ambient in typical automotive layouts.
