Product details
Overview
TPC36AHM3_A/H from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMPC (TO-277A) package, designed for high-reliability automotive and industrial surge protection. It features a 36.0 V nominal breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), clamping voltage of 49.9 V at 30.1 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPC36AHM3_A/H datasheet, TPC36AHM3_A/H pinout, TPC36AHM3_A/H application, or TPC36AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 1.1 mm height, MSL Level 1 rating, and suitability for protecting MOSFETs, sensor signal lines, and ICs against inductive switching transients in automotive ECUs and power electronics.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time under 10/1000 µs surge conditions. Its unidirectional architecture enables robust forward conduction during clamping while maintaining tight VBR tolerance (±5.3% at 25 °C) and stable temperature coefficient (0.090 %/°C).
The device is rated for non-repetitive 1500 W peak pulse power per JEDEC-standard 10/1000 µs waveform and supports 200 A peak forward surge current (IFSM) with 3.5 V max forward voltage at 100 A - critical for minimizing conduction loss during high-current transients in DC bus and motor drive protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nom) | 36.0 V - precise breakdown threshold ensures reliable triggering before downstream component damage |
| VWM | 30.8 V - maximum continuous reverse voltage without significant leakage, enabling safe operation across 24 V automotive systems |
| VC @ IPPM | 49.9 V - clamping voltage at 30.1 A defines worst-case overvoltage seen by protected circuitry |
| PPPM | 1500 W - peak pulse power handling capability for standardized 10/1000 µs surges per IEC 61000-4-5 |
| TJ max | +185 °C - extended junction temperature rating supports under-hood automotive placement without derating |
| Package | SMPC (TO-277A) - surface-mount, low-profile (1.1 mm typical height), AEC-Q101 qualified, halogen-free and RoHS-compliant |
Pinout & Package
TPC36AHM3_A/H is housed in a 3-terminal SMPC (TO-277A) package with cathode band marking on terminal 1. The package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards, and meets JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Anode-side reference node | Marked cathode band identifies polarity; connects to protected line (e.g., 24 V rail or signal input) |
| 2 (Cathode) | Second cathode connection | Dual-cathode configuration lowers dynamic impedance and improves current sharing during high-energy transients |
| 3 (Anode) | Common ground return | Low-inductance anode path to system ground minimizes clamping overshoot in fast-rising ESD/surge events |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Enables stable VBR performance and long-term reliability under thermal cycling and humidity stress |
| AEC-Q101 qualification | Validated for automotive-grade production use including temperature cycling, HTRB, and ESD testing per stress test plan |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility without dry-pack requirements or baking |
| Very low profile (1.1 mm typical height) | Reduces board-level mechanical interference and enables compact layout in space-constrained modules like ADAS sensors |
| Low incremental surge resistance | Minimizes clamping voltage rise under high di/dt conditions, improving protection margin for sensitive gate drivers |
Applications
| Automotive Power Distribution | Industrial Motor Drive Protection |
|---|---|
Use Scenario: Protecting 24 V supply rails in body control modules and junction boxes from load-dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery input and DC/DC converter input stage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57T (Vishay) | Same VBR (36 V), but lower PPPM = 400 W; DO-214AC package; higher profile (2.3 mm) | Limited to lower-energy transients; unsuitable for load-dump or high-current inductive switching | Select only for cost-sensitive consumer applications where 1500 W rating is unnecessary |
| TPC36AHM3_A/I (Vishay) | Identical electrical specs and package; differs only in tape-and-reel packaging (6500 pcs vs. 1500 pcs per reel) | No functional difference; choice depends solely on production volume and SMT line feed requirements | Choose TPC36AHM3_A/I for high-volume automated assembly requiring larger reels |
Compared with SMAJ36A-E3/57T and TPC36AHM3_A/I, the TPC36AHM3_A/H delivers full 1500 W surge capability in a low-profile automotive-qualified package, whereas SMAJ36A-E3/57T trades power for cost and TPC36AHM3_A/I offers identical performance in alternate packaging - making TPC36AHM3_A/H optimal for space-constrained, high-reliability 24 V systems.

FAQ
What is the clamping voltage of the TPC36AHM3_A/H at its rated peak pulse current?
The TPC36AHM3_A/H has a maximum clamping voltage (VC) of 49.9 V at 30.1 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events and is measured per ANSI/IEEE C62.35. The TPC36AHM3_A/H maintains this clamping performance across its full operating temperature range, supporting robust protection in under-hood automotive applications.
Is the TPC36AHM3_A/H qualified for automotive use?
Yes, the TPC36AHM3_A/H is AEC-Q101 qualified and explicitly rated for automotive-grade applications. It meets all stress tests defined in the AEC-Q101 standard, including temperature cycling, highly accelerated stress testing (HAST), and ESD. Its +185 °C maximum junction temperature, MSL Level 1 rating, and halogen-free, RoHS-compliant construction further validate its suitability for engine control units, body electronics, and ADAS modules where long-term reliability under thermal and mechanical stress is required.
What does the "HM3_A/H" suffix indicate in TPC36AHM3_A/H?
The "HM3_A/H" suffix in TPC36AHM3_A/H specifies the packaging and revision: "HM3" denotes the halogen-free, RoHS-compliant, AEC-Q101-qualified base variant in SMPC (TO-277A) package; "A" is the revision code; and "H" indicates the preferred package code for 7-inch plastic tape-and-reel delivery with 1500 units per reel. This suffix distinguishes it from alternate packaging variants such as TPC36AHM3_A/I (13-inch reel, 6500 units).
How does the dual-cathode configuration of the TPC36AHM3_A/H improve surge handling?
The TPC36AHM3_A/H uses a dual-cathode (Terminals 1 and 2) and single-anode (Terminal 3) configuration to reduce effective dynamic impedance during high-current transients. This parallel cathode structure lowers total surge resistance, resulting in tighter clamping voltage control and improved current sharing under 10/1000 µs pulses. In practice, this enhances protection margin for sensitive components like MOSFET gates and microcontroller I/O pins compared to single-cathode TVS devices with identical VBR and PPPM ratings.
Can the TPC36AHM3_A/H be used in bidirectional protection circuits?
No, the TPC36AHM3_A/H is strictly unidirectional and not suitable for bidirectional transient suppression. Its internal structure supports conduction only from anode to cathode during overvoltage events, making it appropriate for DC power rail and signal-line protection where polarity is fixed. For AC or bidirectional signal paths (e.g., USB, RS-485), a dedicated bidirectional TVS such as SMBJ36CA must be selected - the TPC36AHM3_A/H will not clamp negative-going transients and may fail catastrophically if reverse-biased beyond its VWM.
