Product details
Overview
TPC36CAHM3/I from Vishay General Semiconductor is a bidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, featuring breakdown voltage of 34.2–37.8 V, clamping voltage of 49.9 V at 30.1 A, and AEC-Q101 qualification for automotive-grade reliability. It protects sensitive ICs and MOSFETs against inductive load switching transients in engine control units and sensor interfaces.
For engineers reviewing the TPC36CAHM3/I datasheet, TPC36CAHM3/I pinout, TPC36CAHM3/I application, or TPC36CAHM3/I equivalent, key selection criteria include its 30.8 V stand-off voltage, 185 °C junction temperature rating, bidirectional polarity, low-profile 1.1 mm height, and J-STD-020 MSL Level 1 compliance for reflow soldering.
Technical Context
The TPC36CAHM3/I implements a junction-passivated PAR® structure optimized for fast response to transient overvoltages, with clamping action triggered within picoseconds of surge onset. Its bidirectional design enables symmetric protection on AC-coupled or floating signal lines without polarity constraints.
Rated for 1500 W peak pulse power under 10/1000 μs waveform, it sustains repetitive surges up to TJ = 185 °C and meets automotive reliability requirements per AEC-Q101. The device operates with ≤1.0 μA reverse leakage at 30.8 V and exhibits stable clamping performance across -65 °C to +185 °C junction temperature range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/57T | Unidirectional; 33 V VWM; 500 W PPPM; SMA package (higher profile, lower power) | Limited to DC-biased lines; unsuitable for AC or floating signals without external biasing | Select when cost sensitivity outweighs power handling and bidirectionality needs |
| TPC33CAHM3/I | Lower VWM (28.2 V); lower clamping (45.7 V @ 32.8 A); same package and AEC-Q101 rating | Better suited for 24 V systems requiring tighter voltage margin before clamping onset | Choose for 24 V nominal systems where 30.8 V VWM would risk premature conduction |
Compared with SMAJ33A-E3/57T, the TPC36CAHM3/I delivers 3× higher surge power and true bidirectional protection in a lower-profile package; versus TPC33CAHM3/I, it offers higher voltage standoff for 36 V system compatibility but requires verification of clamping headroom in downstream circuits.

FAQ
What is the maximum clamping voltage of the TPC36CAHM3/I under surge conditions?
The TPC36CAHM3/I has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current of 30.1 A under the standard 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events. The TPC36CAHM3/I maintains this clamping performance across its full operating temperature range and is validated per ANSI/IEEE C62.35 standards.
Is the TPC36CAHM3/I suitable for automotive applications?
Yes, the TPC36CAHM3/I is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, camera modules, and body electronics. Its 185 °C maximum junction temperature, MSL Level 1 reflow compatibility, halogen-free construction, and bidirectional architecture meet stringent automotive reliability and manufacturing requirements. The TPC36CAHM3/I is listed in Vishay's automotive-grade product portfolio with full qualification documentation available upon request.
What does the "HM3" suffix indicate in TPC36CAHM3/I?
The "HM3" suffix in TPC36CAHM3/I denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101-qualified variant in the SMPC (TO-277A) package. The "H" indicates tape-and-reel packaging (13-inch reel), and "M3" specifies the material and qualification level - including JESD 201 Class 2 whisker resistance and compliance with UL 94 V-0 flammability. The TPC36CAHM3/I is not a generic variant but a fully specified automotive-grade part with documented process and reliability validation.
How does the bidirectional nature of the TPC36CAHM3/I affect its circuit placement?
The bidirectional design of the TPC36CAHM3/I eliminates polarity concerns during PCB layout - either terminal may connect to line or return without functional impact. This simplifies routing on AC-coupled, differential, or floating signal paths such as CAN bus, LIN, or sensor bridges. Unlike unidirectional TVS diodes, the TPC36CAHM3/I requires no external biasing or orientation checks, reducing assembly errors and enabling symmetric protection schemes in the TPC36CAHM3/I application.
What is the thermal derating behavior of the TPC36CAHM3/I above 25 °C ambient?
The TPC36CAHM3/I follows standard JEDEC thermal derating curves: peak pulse power decreases linearly above 25 °C ambient, reaching ~50 % of rated 1500 W at +125 °C case temperature. Derating is based on junction temperature limits (TJ ≤ 185 °C), and actual performance depends on PCB copper area, airflow, and mounting configuration. Vishay provides derating graphs in Figure 2 of document 87649; users must validate thermal design using the TPC36CAHM3/I's specific RθJA and expected surge duty cycle.
