Product details
Overview
TPC11CAHM3/H from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in the SMPC (TO-277A) package, featuring a standoff voltage of 9.4 V, breakdown voltage of 10.5–11.6 V at 1 mA, clamping voltage of 15.6 V at 96.2 A, and AEC-Q101 qualification for automotive-grade reliability. It protects sensitive ICs and MOSFETs against inductive switching transients in engine control units and sensor signal lines.
For engineers reviewing the TPC11CAHM3/H datasheet, TPC11CAHM3/H pinout, TPC11CAHM3/H application, or TPC11CAHM3/H equivalent, key selection criteria include its 1500 W peak pulse power rating, bidirectional polarity, 185 °C junction temperature capability, low-profile 1.1 mm height, and halogen-free RoHS-compliant construction with JESD201 Class 2 whisker resistance.
Technical Context
The TPC11CAHM3/H implements a junction-passivated PAR® design optimized for fast response to transient overvoltages, with clamping performance defined under standardized 10/1000 μs surge waveforms. Its bidirectional structure enables symmetric protection without polarity sensitivity, and it operates across -65 °C to +185 °C junction temperature range.
Designed for surface-mount automated placement, the device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak, and its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability standards. The SMPC package provides mechanical robustness while maintaining minimal PCB footprint and thermal resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/5AT | Unidirectional; 10 V VWM; 1500 W PPPM; DO-214AC package; 2.3 mm height | Requires correct polarity orientation; less suitable for AC-coupled or floating signal lines | Select when unidirectional clamping suffices and board height allows larger package |
| TPC12CAHM3/H | Higher VWM (10.2 V); higher VBR (11.4–12.6 V); same package, AEC-Q101, and 1500 W rating | Better suited for systems with higher nominal rail voltage or tighter margin above 10 V | Choose for 12 V nominal systems where 9.4 V VWM may risk false triggering during ripple |
Compared with SMAJ10A-E3/5AT and TPC12CAHM3/H, the TPC11CAHM3/H offers the lowest VWM in the TPCxxCA family while retaining identical AEC-Q101 qualification, SMPC packaging, and 1500 W surge capability-making it optimal for 9–10 V rail protection where minimal clamping threshold is critical.

FAQ
What is the maximum clamping voltage of the TPC11CAHM3/H under a 10/1000 μs surge?
The TPC11CAHM3/H has a maximum clamping voltage (VC) of 15.6 V when subjected to its rated peak pulse current of 96.2 A under the standardized 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The TPC11CAHM3/H maintains this clamping performance across its full operating temperature range, with derating applied only above 25 °C ambient per the published derating curve.
Is the TPC11CAHM3/H suitable for automotive applications?
Yes, the TPC11CAHM3/H is AEC-Q101 qualified and explicitly designed for automotive use, with features including 185 °C maximum junction temperature, halogen-free and RoHS-compliant construction, JESD201 Class 2 whisker resistance, and MSL Level 1 moisture sensitivity rating. Its bidirectional architecture and low-profile SMPC package make the TPC11CAHM3/H ideal for engine control units, body electronics, and sensor interfaces where space and reliability are critical.
What does the "HM3" suffix indicate in TPC11CAHM3/H?
The "HM3" suffix in TPC11CAHM3/H denotes Vishay's automotive-grade ordering code: "H" specifies the halogen-free, RoHS-compliant molding compound, "M3" indicates the tape-and-reel packaging format (7-inch reel, 1500 units), and the trailing "/H" confirms compliance with JESD201 Class 2 whisker testing. This suffix distinguishes the TPC11CAHM3/H from commercial variants and confirms its suitability for automotive production environments.
How does the TPC11CAHM3/H differ from the TPC11CAHM3/I variant?
The TPC11CAHM3/H and TPC11CAHM3/I share identical electrical specifications and SMPC packaging but differ only in packaging configuration: TPC11CAHM3/H ships on 7-inch plastic tape-and-reel (1500 units/reel), while TPC11CAHM3/I uses 13-inch tape-and-reel (6500 units/reel). Both versions carry the same HM3 automotive qualification and are functionally interchangeable in design; the choice depends solely on production volume and SMT line feed requirements for the TPC11CAHM3/H or TPC11CAHM3/I.
Does the TPC11CAHM3/H require polarity-aware PCB layout?
No, the TPC11CAHM3/H is a bidirectional TVS device with no polarity marking on the SMPC package, meaning either terminal can be connected to the line or ground side of the protected circuit. Its symmetrical breakdown and clamping characteristics eliminate the need for orientation-specific placement, simplifying layout and reducing assembly errors-particularly valuable in differential or AC-coupled signal paths where the TPC11CAHM3/H is commonly deployed.
