Product details
Overview
TPC36HM3/86A from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in TO-277A (SMPC) package, designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 32.4 V to 39.6 V breakdown voltage range, 29.1 V stand-off voltage, 52.0 V maximum clamping voltage at 28.8 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TPC36HM3/86A datasheet, TPC36HM3/86A pinout, TPC36HM3/86A application, or TPC36HM3/86A equivalent, key selection criteria include unidirectional clamping capability, 185 °C junction temperature rating, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement in high-reliability power rail protection circuits.
Technical Context
The TPC36HM3/86A employs passivated anisotropic rectifier technology optimized for fast response and low incremental surge resistance. Its unidirectional architecture provides forward conduction path during overvoltage events while maintaining low leakage (<1 μA at 29.1 V, 25 °C) under normal operation.
Designed for automotive and industrial environments, it delivers stable clamping performance across -65 °C to +185 °C operating junction temperature, with thermal derating per JEDEC J-STD-020 and compliance to AEC-Q101 stress test requirements including temperature cycling, HTRB, and ESD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 32.4 V / 39.6 V - defines reliable avalanche initiation threshold across production lot and temperature range |
| VWM | 29.1 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 52.0 V at 28.8 A - clamping voltage limiting downstream component stress during 10/1000 µs surge |
| PPPM | 1500 W - peak pulse power handling capacity for transient suppression without failure |
| TJ max | +185 °C - enables operation in under-hood automotive and high-temperature industrial enclosures |
| Package | TO-277A (SMPC) - surface-mount, 3-terminal, 1.1 mm profile, compatible with standard reflow profiles |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTGB, H3TRB, and TCT |
Pinout & Package
TO-277A (SMPC) is a 3-terminal surface-mount package with cathode-anode-cathode configuration. Its low-profile construction (1.1 mm typical height), matte tin-plated leads, and UL 94 V-0 molding compound support high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Reverse-biased terminal | Connected to protected line; conducts when voltage exceeds VBR to shunt surge energy to ground |
| 2 (Anode) | Reference/ground node | Typically tied to system ground or low-impedance return path; establishes clamping reference potential |
| 3 (Cathode) | Reverse-biased terminal | Electrically identical to Pin 1; dual-cathode layout improves current sharing and thermal distribution |
Key Features
| Feature | Design Value |
|---|---|
| Passivated anisotropic rectifier technology | Enables precise VBR control and stable clamping over lifetime and temperature |
| 185 °C junction temperature rating | Supports deployment in engine control units, ADAS modules, and industrial motor drives without derating |
| 1.1 mm profile | Reduces board space and enables use in ultra-thin consumer and automotive ECUs |
| MSL Level 1 | Eliminates bake-out requirement prior to reflow, reducing manufacturing cost and cycle time |
| Halogen-free, RoHS-compliant | Meets global environmental compliance mandates including EU RoHS Directive 2011/65/EU |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/5A (Vishay) | Lower PPPM (400 W), SMA package, 33 V VWM, 53.3 V VC @ 7.5 A | Targeted for lower-energy consumer electronics; not AEC-Q101 qualified | Choose for cost-sensitive non-automotive designs where 1500 W surge immunity is unnecessary |
| TPC33AHM3/86A (Vishay) | Lower VBR (29.7–36.3 V), 47.7 V VC @ 31.4 A, same package and qualification | Better suited for 24 V nominal systems requiring tighter clamping margin below 50 V | Prefer when protecting 3.3 V/5 V logic powered from regulated 24 V rails with stricter VC ceiling |
Compared with SMAJ33A-E3/5A, TPC36HM3/86A delivers >260 % higher surge power handling and automotive qualification; versus TPC33AHM3/86A, it offers higher VWM and VBR for 36 V nominal systems, trading slightly higher clamping voltage for improved system margin against false triggering.

FAQ
What is the maximum clamping voltage of the TPC36HM3/86A under standard 10/1000 µs surge conditions?
The TPC36HM3/86A has a maximum clamping voltage (VC) of 52.0 V at 28.8 A peak pulse current (IPPM) under standardized 10/1000 µs waveform testing. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream components in automotive and industrial applications.
Is the TPC36HM3/86A suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the TPC36HM3/86A is explicitly AEC-Q101 qualified per the Vishay datasheet (Document Number: 89056, Revision: 15-Aug-16). It meets all required stress tests including high-temperature reverse bias, temperature cycling, and humidity testing, making it appropriate for under-hood and safety-critical automotive subsystems.
What does the "HM3/86A" suffix indicate in the TPC36HM3/86A part number?
The "HM3" denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance, while "86A" specifies the preferred packaging: 7-inch plastic tape and reel with 1500 units per reel. This packaging format supports automated SMT placement and complies with industry-standard handling requirements.
Does the TPC36HM3/86A have bidirectional or unidirectional polarity?
The TPC36HM3/86A is strictly unidirectional, as confirmed by its electrical characteristics table and feature list. It functions as a single-polarity avalanche diode, conducting only when reverse voltage exceeds its breakdown range (32.4–39.6 V); it does not provide symmetrical clamping for AC or bipolar transients.
What is the thermal performance limit for continuous operation of the TPC36HM3/86A?
The TPC36HM3/86A supports continuous operation from -65 °C to +185 °C junction temperature. Its thermal impedance curve (Fig. 5) shows RthJA ≈ 40 °C/W when mounted on a 2 oz. copper PCB per JEDEC TO-277A recommendations, enabling reliable performance in high-ambient environments without active cooling.
