Product details
Overview
TPC7.5HM3/86A 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 breakdown voltage of 7.13–7.88 V at 10 mA, clamping voltage of 11.3 V at 133 A peak pulse current, and operates up to 185 °C junction temperature.
For engineers reviewing the TPC7.5HM3/86A datasheet, TPC7.5HM3/86A pinout, TPC7.5HM3/86A application, or TPC7.5HM3/86A equivalent, key selection criteria include unidirectional clamping performance, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on sensor signal lines and MOSFET gate drivers.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time under 10/1000 μs transients. Its junction passivation enables stable operation at TJ = 185 °C, meeting automotive-grade reliability requirements per AEC-Q101.
The device is rated for 1500 W peak pulse power, with clamping voltage tightly controlled at 11.3 V under 133 A IPPM. Its SMPC (TO-277A) package supports high-density PCB layouts with 1.1 mm typical height and matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.13 / 7.50 / 7.88 V at 10 mA - ensures precise breakdown threshold for overvoltage triggering |
| VWM | 6.40 V - maximum continuous reverse working voltage before leakage exceeds 500 μA |
| VC @ IPPM | 11.3 V at 133 A - clamping voltage limits downstream IC stress during 10/1000 μs surge |
| PPPM | 1500 W - peak pulse power handling capability per single non-repetitive event |
| TJ max. | +185 °C - enables use in under-hood automotive environments without derating |
| Polarity | Unidirectional - protects only against positive-going transients on anode-to-cathode path |
| MSL Level | Level 1 per J-STD-020 - allows unlimited floor life and reflow without baking |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal configuration with cathode band marking. Dimensions conform to JEDEC TO-277A standard: 4.80 × 3.70 × 1.10 mm (L × W × H), 2.13 mm nominal standoff height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Terminal 3) | Surge current entry point | Connected to protected line; conducts during forward-biased transient events |
| Cathode 1 (Terminal 1) | Common cathode connection | Internally tied to Cathode 2; provides low-inductance return path to ground |
| Cathode 2 (Terminal 2) | Common cathode connection | Electrically identical to Terminal 1; dual-cathode layout reduces thermal resistance |
Key Features

Applications
| Automotive Sensor Protection | Industrial Motor Drive Gate Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and Hall-effect position sensors from load-dump and inductive switching transients in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output line and ground to clamp positive surges before they reach IC input pins. Use Value: Clamps 133 A surge to ≤11.3 V, preventing damage to 5 V tolerant sensor interface circuitry while maintaining signal integrity. | Use Scenario: Safeguarding IGBT gate drivers in variable-frequency drives exposed to Miller-induced voltage spikes during high dv/dt switching. IC Role / Device Role / Timing Role: TVS connected between gate and emitter to suppress transient overshoot exceeding ±20 V absolute maximum rating. Use Value: Limits gate voltage excursion within safe operating area using 11.3 V clamping, avoiding unintended turn-on or oxide degradation. |
| Telecom Power Input Protection | Consumer USB-C ESD/Surge Combo |
Use Scenario: Front-end protection of 48 V PoE-powered switches against lightning-induced surges on Ethernet data lines. IC Role / Device Role / Timing Role: Unidirectional TVS installed on each differential pair to absorb common-mode transients before reaching PHY ICs. Use Value: Withstands 1500 W peak power and maintains <500 μA leakage at 6.4 V, preserving low-noise signal integrity. | Use Scenario: Secondary-level surge suppression on VBUS line of USB-C receptacles in portable docking stations. IC Role / Device Role / Timing Role: TVS placed after primary ESD array to handle higher-energy surges that bypass initial protection. Use Value: Provides robust 133 A surge handling with 11.3 V clamping, complementing low-capacitance ESD diodes without compromising data rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Lower PPPM (400 W), SMA package (higher thermal resistance), VC = 12.0 V at 32.4 A | Not AEC-Q101 qualified; limited to commercial/industrial use, not automotive | Select when cost-sensitive, lower-energy transients (<400 W) and non-automotive qualification suffice |
| TPC7.5HM3_A | Same electrical specs and SMPC package; differs only in tape-and-reel packaging code (A vs. 86A) | No functional difference; identical performance and reliability in circuit | Choose based on preferred reel size (1500 vs. 6500 units) and logistics compatibility |
Compared with SMAJ7.5A, TPC7.5HM3/86A delivers 3.75× higher surge power handling and automotive qualification; compared with TPC7.5HM3_A, it offers identical protection performance but with different packaging configuration for volume production planning.

FAQ
What is the breakdown voltage tolerance of TPC7.5HM3/86A?
The TPC7.5HM3/86A has a specified breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, corresponding to ±5 % around the nominal 7.50 V value. This tolerance is confirmed in the Electrical Characteristics table of Vishay document 89056 and applies across the full operating temperature range when adjusted using the published temperature coefficient of 0.052 %/°C.
Is TPC7.5HM3/86A suitable for bidirectional transient protection?
No, TPC7.5HM3/86A is strictly unidirectional and only protects against positive-going voltage transients on the anode-to-cathode path. For bidirectional protection, Vishay offers separate part numbers such as the TPSM7.5A series. Using TPC7.5HM3/86A in reverse-biased configurations may result in premature failure due to lack of reverse breakdown specification.
Does TPC7.5HM3/86A require derating at elevated ambient temperatures?
Yes, TPC7.5HM3/86A must be derated above TA = 25 °C per Figure 2 in Vishay document 89056. At 100 °C ambient, its peak pulse power drops to approximately 65 % of the rated 1500 W, and at 150 °C, it falls to ~35 %. Derating ensures safe operation within the 185 °C maximum junction temperature limit.
What is the mounting pad layout recommendation for TPC7.5HM3/86A?
Vishay specifies a recommended copper pad layout for TPC7.5HM3/86A in Document 89056: minimum pad dimensions of 4.72 mm × 6.80 mm (L × W), with 1.27 mm minimum solder mask opening and 1.04 mm minimum stencil aperture. Thermal relief vias are advised beneath the cathode pads to enhance heat dissipation during surge events.
How does the HM3/86A suffix affect the electrical performance of TPC7.5HM3/86A?
The HM3/86A suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It does not alter the electrical characteristics of TPC7.5HM3/86A - all parameters including VBR, VC, and PPPM remain identical to other TPC7.5A variants sharing the same base part number and revision code.
