Product details
Overview
TPC13CAHM3/H from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in the SMPC (TO-277A) package, designed for high-reliability automotive and industrial electronics protection. It features a standoff voltage of 11.1 V, breakdown voltage range of 12.4–13.7 V at 1 mA, clamping voltage of 18.2 V at 82.4 A, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC13CAHM3/H datasheet, TPC13CAHM3/H pinout, TPC13CAHM3/H application, or TPC13CAHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, MSL Level 1 rating, halogen-free RoHS-compliant construction, and suitability for inductive load switching transients on sensor signal lines and MOSFET gate drivers.
Technical Context
The TPC13CAHM3/H implements a junction-passivated PAR® structure optimized for fast response to 10/1000 μs surge waveforms while maintaining low leakage (<2 μA at 11.1 V). Its bidirectional symmetry enables protection of AC-coupled or differential signal paths without polarity constraints.
Rated for 1500 W peak pulse power and 82.4 A peak pulse current, it delivers stable clamping performance across -65 °C to +185 °C operating range, with derating applied above 25 °C ambient per Fig. 2. The device meets JESD201 Class 2 whisker resistance and J-STD-020 reflow compatibility up to 260 °C peak.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12CA | Lower PPPM (400 W), higher VWM (12 V), same SMAs package (larger footprint, lower thermal mass) | Not AEC-Q101 qualified; limited to commercial/industrial use below 150 °C | Select when cost sensitivity outweighs automotive qualification and surge energy requirements are ≤400 W |
| TPC12CAHM3/H | Lower VWM (10.2 V), lower VC (16.7 V), same package and AEC-Q101 qualification | Better suited for 9–10 V nominal rail protection where tighter clamping margin is required | Choose for 9 V systems needing lower turn-on threshold while retaining identical mounting and qualification |
Compared with SMAJ12CA and TPC12CAHM3/H, the TPC13CAHM3/H offers balanced clamping (18.2 V) and standoff (11.1 V) for 12 V automotive subsystems, with superior 1500 W surge capacity and full AEC-Q101 compliance-making it optimal for engine control, ADAS sensor hubs, and body electronics requiring high-reliability transient immunity.

FAQ
What is the maximum clamping voltage of the TPC13CAHM3/H under rated surge conditions?
The TPC13CAHM3/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 82.4 A using a 10/1000 μs waveform. This value is measured at the device terminals and ensures downstream components remain within safe voltage limits during transient events. The clamping performance is guaranteed across the full operating temperature range up to +185 °C junction temperature.
Is the TPC13CAHM3/H qualified for automotive applications?
Yes, the TPC13CAHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating compliance with automotive reliability standards, including high-temperature operating life, humidity bias, and mechanical shock testing. It is explicitly intended for use in automotive subsystems such as body control modules, ADAS sensors, and powertrain electronics where robustness against electrical transients is critical.
What does the "HM3" suffix indicate in TPC13CAHM3/H?
The "HM3" suffix in TPC13CAHM3/H denotes halogen-free, RoHS-compliant construction, AEC-Q101 qualification, and compliance with JESD201 Class 2 whisker resistance. It also specifies packaging in 7-inch plastic tape and reel (1500 units per reel), with matte tin-plated leads solderable per J-STD-002 and JESD22-B102 standards.
Can the TPC13CAHM3/H be used in bidirectional signal line protection?
Yes, the TPC13CAHM3/H is inherently bidirectional and requires no polarity marking or orientation during placement. Its symmetrical breakdown characteristics (12.4–13.7 V in both directions) make it ideal for protecting AC-coupled data lines, differential buses like CAN or RS-485, and other bidirectional interfaces where transient polarity cannot be predicted or controlled.
What is the thermal derating behavior of the TPC13CAHM3/H above 25 °C ambient?
The TPC13CAHM3/H follows standard derating curves per Figure 2 in its datasheet: peak pulse power decreases linearly from 100% at 25 °C to approximately 50% at +125 °C ambient. At +150 °C, derating reaches ~30%, and operation remains valid up to +185 °C junction temperature. Designers must calculate actual junction temperature using thermal resistance and power dissipation to ensure safe margins.
