Product details
Overview
TPSMC10HE3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 10 V nominal breakdown voltage (VBR), 8.55 V maximum stand-off voltage (VWM), 14.5 V clamping voltage at 103 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - ideal for automotive power rail protection.
For engineers reviewing the TPSMC10HE3/57T datasheet, TPSMC10HE3/57T pinout, TPSMC10HE3/57T application, or TPSMC10HE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 10/1000 µs waveform clamping performance, thermal derating above 25 °C, and compatibility with automated SMT assembly under J-STD-020 MSL level 1.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress and high-temperature operation. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments where thermal cycling and long-term reliability are critical.
The device exhibits low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, load dump, and inductive switching transients. Its 10/1000 µs waveform rating (1500 W) and 200 A non-repetitive forward surge capability (8.3 ms half-sine) support robust front-end protection in 12 V and 24 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 V / 10.0 V / 10.5 V - ensures reliable conduction onset above system operating voltage while avoiding false triggering |
| VWM | 8.55 V - maximum continuous reverse voltage before leakage exceeds 20 µA, compatible with 5–8 V logic and 12 V supply rails |
| VC @ IPPM | 14.5 V - clamping voltage at 103 A peak pulse, limiting downstream IC stress during 1500 W transients |
| PPPM | 1500 W - peak pulse power handling per 10/1000 µs waveform, sufficient for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges |
| TJ max. | +185 °C - enables placement near heat sources (e.g., power MOSFETs, DC/DC converters) without derating loss |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation toward protected line |
| Package | SMC (DO-214AB) - industry-standard 2-pin surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement for thermal dissipation |
Pinout & Package
TPSMC10HE3/57T is housed in an SMC (DO-214AB) plastic package with matte tin-plated leads. The cathode is marked by a color band on the body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path | Connected to ground or low-impedance reference; completes clamping loop during overvoltage events |
| Cathode | Protected line connection | Connected to the line being safeguarded (e.g., battery feed, sensor VCC); conducts when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards |
| Junction passivation | Reduces surface leakage and improves long-term stability under high-humidity and high-bias conditions |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or dry-pack requirements |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD, relay bounce), improving clamping fidelity |
| 1500 W 10/1000 µs rating | Supports sustained suppression of high-energy transients common in 12 V/24 V vehicle electrical systems |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppresses load dump pulses (ISO 7637-2 Pulse 5a) on 12 V battery-fed ECUs and body control modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same 10 V VBR, but lower PPPM = 400 W; SMA package (smaller thermal mass) | Limited to low-energy transients (e.g., ESD-only); unsuitable for load dump or lightning surge | Select when space-constrained and surge energy is <400 W; verify thermal design with smaller pad area |
| TPSMC10AHM3 | Identical electrical specs; halogen-free molding compound and whisker-tested leads (JESD201 Class 2) | Required for RoHS+halogen-free compliance programs; same AEC-Q101 qualification | Choose for green manufacturing mandates; no layout or performance trade-offs vs. TPSMC10HE3/57T |
Compared with SMAJ10A and TPSMC10AHM3, TPSMC10HE3/57T offers the highest surge energy handling (1500 W) in its footprint and meets automotive qualification without halogen-free constraints - making it optimal for cost-sensitive, thermally demanding 12 V systems where full AEC-Q101 compliance is required but halogen-free is optional.

FAQ
What is the maximum clamping voltage of the TPSMC10HE3/57T under rated surge conditions?
The TPSMC10HE3/57T has a maximum clamping voltage (VC) of 14.5 V at 103 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during a 1500 W transient event. Engineers must ensure downstream components tolerate this clamped voltage under worst-case surge timing.
Is the TPSMC10HE3/57T qualified for automotive applications?
Yes, the TPSMC10HE3/57T is AEC-Q101 qualified, confirming compliance with stress tests for automotive-grade reliability including temperature cycling, high-temperature operating life, and mechanical shock. Its 185 °C maximum junction temperature and RoHS-compliant construction meet Tier-1 supplier requirements for engine control units, body electronics, and ADAS power domains.
What does the "HE3" suffix indicate in TPSMC10HE3/57T?
The "HE3" suffix denotes Vishay's standard RoHS-compliant, AEC-Q101-qualified variant with matte tin-plated leads and JESD201 Class 2 whisker resistance. The "/57T" indicates tape-and-reel packaging in 13-inch reels (3500 units per reel), per Vishay's preferred ordering code format for automated SMT placement.
Can TPSMC10HE3/57T be used in bidirectional protection circuits?
No, TPSMC10HE3/57T is unidirectional only - it clamps positive transients relative to ground and blocks reverse voltage. For bidirectional protection (e.g., AC lines or data buses), a separate bidirectional TVS like SMBJ10CA or a back-to-back configuration would be required. Using TPSMC10HE3/57T in reverse-biased mode risks permanent breakdown.
What is the recommended PCB pad layout for thermal performance of TPSMC10HE3/57T?
Vishay specifies mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal to achieve rated 1500 W pulse power. Minimum pad dimensions are 0.126" (3.20 mm) wide and 0.185" (4.69 mm) long per side, with thermal vias recommended beneath pads for enhanced heat dissipation in high-duty-cycle applications.
