Product details
Overview
TPSMA10AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power and signal lines. It features a 10 V breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 400 W peak pulse power (10/1000 µs), 27.6 V maximum clamping voltage at 20 A, 1.0 W steady-state power dissipation, and operates up to 185 °C junction temperature - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the TPSMA10AHE3_A/H datasheet, TPSMA10AHE3_A/H pinout, TPSMA10AHE3_A/H application, or TPSMA10AHE3_A/H equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, TJ = 185 °C thermal rating, and clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its unidirectional architecture provides forward conduction only during reverse overvoltage events, with fast response time enabling sub-nanosecond clamping onset.
The device is rated for 40 A non-repetitive peak forward surge current (8.3 ms half-sine), exhibits 0.064 %/°C temperature coefficient of VBR, and meets JESD201 Class 2 whisker resistance and MSL Level 1 (260 °C reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 V / 10.0 V / 10.5 V at 1 mA - defines precise reverse breakdown threshold for reliable clamping initiation |
| VWM | 8.65 V - maximum continuous reverse working voltage before leakage exceeds 5 µA |
| VC @ IPPM | 27.6 V at 20 A - clamping voltage under 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling capability per standard 10/1000 µs waveform |
| TJ max. | 185 °C - enables operation in under-hood automotive and high-ambient industrial environments |
| Polarity | Unidirectional - blocks reverse current until VBR, then clamps; not suitable for AC line protection |
| Package | SMA (DO-214AC) - industry-standard surface-mount outline with cathode band marking |
Pinout & Package
TPSMA10AHE3_A/H is housed in an SMA (DO-214AC) plastic package with matte tin-plated leads. The cathode is marked by a color band; terminals are solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path during clamping | Connected to protected line's ground or low-side return; conducts surge current to reference |
| Cathode | Reverse-biased terminal during normal operation | Connected to protected line (e.g., 12 V rail or signal); initiates clamping when VBR exceeded |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Junction passivation | Optimized anisotropic rectifier structure ensures stable VBR and low leakage over lifetime |
| MSL Level 1 | Rated for peak reflow at 260 °C without moisture-induced damage |
| Low clamping ratio | VC/VBR ≈ 2.76 - tight voltage margin between trigger and clamp improves system-level surge margin |
| High IFSM | 40 A surge withstand (8.3 ms) supports robust protection against motor-switching transients |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before reaching sensitive input stages. Use Value: Clamps 27.6 V at 20 A while maintaining <5 µA leakage at 8.65 V, preserving signal integrity and meeting AEC-Q100 stress requirements. | Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Standoff protector on each channel input, absorbing repetitive 400 W pulses without degradation. Use Value: 185 °C max junction temperature allows mounting near heat-generating power components; RoHS-compliant HE3 suffix supports industrial compliance mandates. |
| Consumer Power Adapter Protection | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters and USB PD chargers exposed to mains coupling and ESD events. IC Role / Device Role / Timing Role: Fast-response clamping device across output rails (e.g., 5 V, 9 V, 12 V) to prevent regulator latch-up or capacitor failure. Use Value: 1.0 W steady-state power rating enables continuous operation; 0.064 %/°C VBR TC ensures stable trip point across ambient range. | Use Scenario: Surge protection on Ethernet PHY interface lines (e.g., MDI-X pairs) and RS-485 data buses in base stations and network equipment. IC Role / Device Role / Timing Role: Low-capacitance unidirectional suppressor placed differential-to-ground to limit common-mode transients without distorting high-speed signals. Use Value: Meets IEC 61000-4-5 Level 3 (1 kV/2 kV) requirements; SMA footprint allows dense layout on compact telecom PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VBR range (9.5–10.5 V), but SMB package (DO-214AA); 600 W PPPM; higher IPPM (32.5 A) | Larger footprint; better suited for higher-energy surges where board space permits | Select SMBJ10A when 600 W pulse rating is required and DO-214AA pad layout is available |
| 1.5SMC10A | Same VBR, SMC (DO-214AB) package; 1500 W PPPM; higher VC (17.0 V @ 87.2 A) | Higher surge capacity but larger size and higher clamping voltage; not AEC-Q101 qualified | Choose 1.5SMC10A for non-automotive, high-energy industrial applications needing >400 W rating |
Compared with SMBJ10A and 1.5SMC10A, the TPSMA10AHE3_A/H delivers AEC-Q101 qualification and MSL Level 1 reflow compatibility in the smallest DO-214AC footprint, making it optimal for space-constrained automotive and portable electronics where thermal robustness and process reliability are critical.

FAQ
What is the exact breakdown voltage tolerance for TPSMA10AHE3_A/H?
The TPSMA10AHE3_A/H has a guaranteed breakdown voltage range of 9.5 V to 10.5 V at 1.0 mA test current, per the Electrical Characteristics table in Vishay document 88405. This ±5 % tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design in safety-critical circuits.
Is TPSMA10AHE3_A/H qualified for automotive use?
Yes, TPSMA10AHE3_A/H is AEC-Q101 qualified - confirmed in the "FEATURES" section and ordering information of Vishay document 88405. The HE3 suffix denotes RoHS-compliant, AEC-Q101 qualified construction, validated for temperature cycling, highly accelerated life testing, and mechanical shock per automotive reliability standards.
What does the "HE3" suffix mean in TPSMA10AHE3_A/H?
The "HE3" suffix in TPSMA10AHE3_A/H indicates RoHS-compliant construction with matte tin-plated leads, JESD201 Class 2 whisker resistance, and AEC-Q101 qualification. The "_A/H" denotes revision code A and tape-and-reel packaging in 7-inch reels (1800 units per reel), per Vishay's ordering information table.
Can TPSMA10AHE3_A/H be used in bidirectional applications?
No, TPSMA10AHE3_A/H is unidirectional only, as explicitly stated in the FEATURES section of the datasheet. It clamps only in reverse bias; forward conduction occurs above ~3.5 V. For bidirectional protection (e.g., AC lines or differential data), a separate device such as TPSMA10CA or dual-series configuration is required.
What is the maximum clamping voltage of TPSMA10AHE3_A/H at rated surge current?
The maximum clamping voltage (VC) of TPSMA10AHE3_A/H is 27.6 V at 20 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 and Table "ELECTRICAL CHARACTERISTICS" in Vishay document 88405 and defines the upper voltage limit imposed on protected circuitry during surge events.
