Product details
Overview
TPSMB10AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching and lightning-induced transients on power rails and signal lines. It features 10.0 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 14.5 V maximum clamping voltage at 41.4 A peak current, and operates up to +185 °C junction temperature. It is used in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the TPSMB10AHE3_A/H datasheet, TPSMB10AHE3_A/H pinout, TPSMB10AHE3_A/H application, or TPSMB10AHE3_A/H equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, 10.0 V VBR tolerance band, and 14.5 V clamping performance under 41.4 A surge.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation. Its 10/1000 µs waveform rating of 600 W and 41.4 A peak pulse current (IPPM) enables robust protection against repetitive transients in automotive and industrial environments.
The device exhibits low incremental surge resistance and fast response time (<1 ns), delivering precise clamping at 14.5 V when subjected to its rated surge current. Its TJ = –65 °C to +185 °C operating range and MSL Level 1 moisture sensitivity rating support reflow-compatible assembly and extended reliability in harsh thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 / 10.0 / 10.5 V - Ensures reliable turn-on above 9.5 V while maintaining margin below 10.5 V under production variation. |
| VWM | 8.55 V - Maximum continuous reverse voltage before leakage exceeds 5 µA; defines safe operating window for 9–10 V supply rails. |
| VC @ IPPM | 14.5 V - Clamping voltage at 41.4 A surge; limits downstream IC stress during 600 W transient events. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; supports EN 61000-4-5 Level 4 compliance in properly designed layouts. |
| TJ max. | +185 °C - Enables use in under-hood automotive modules and high-ambient industrial enclosures without derating. |
| IFSM | 75 A - 8.3 ms half-sine surge capability; withstands motor startup currents and relay coil flyback energy. |
| Leakage @ VWM | 5 µA - Low standby power loss in battery-powered systems; verified at TA = 25 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, 10 V VBR, but lower PPPM = 400 W and VC = 16.0 V at 25.6 A; not AEC-Q101 qualified. | Acceptable for commercial-grade consumer electronics with lower surge severity; unsuitable for automotive under-hood use. | Select SMAJ10A only if cost sensitivity outweighs automotive qualification and higher clamping margin is acceptable. |
| TPSMB10AHM3_A/H | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 vs. HE3). | Required for halogen-free compliance mandates (e.g., JEDEC J-STD-709); otherwise functionally interchangeable in all designs. | Choose TPSMB10AHM3_A/H when environmental compliance (halogen-free) is specified; otherwise TPSMB10AHE3_A/H is preferred for general AEC-Q101 use. |
Compared with SMAJ10A, TPSMB10AHE3_A/H delivers 50 % higher surge power handling and tighter clamping, enabling robust automotive deployment; versus TPSMB10AHM3_A/H, it offers identical protection performance with standard RoHS-compliant (non-halogen-free) packaging.

FAQ
What is the breakdown voltage tolerance for TPSMB10AHE3_A/H?
The TPSMB10AHE3_A/H has a guaranteed breakdown voltage range of 9.5 V (minimum) to 10.5 V (maximum) at 1 mA test current, with 10.0 V as the nominal value. This ±5 % tolerance ensures predictable turn-on behavior across production lots and temperature extremes, critical for protecting 9–10 V logic rails and analog sensors without false triggering.
Is TPSMB10AHE3_A/H suitable for automotive under-hood applications?
Yes, TPSMB10AHE3_A/H is AEC-Q101 qualified and rated for TJ = –65 °C to +185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and body electronics. Its 185 °C junction rating and validated reliability testing ensure stable operation in high-ambient thermal environments where conventional TVS diodes fail.
What does the "HE3" suffix indicate in TPSMB10AHE3_A/H?
The "HE3" suffix in TPSMB10AHE3_A/H denotes RoHS-compliant construction and full AEC-Q101 qualification. It distinguishes this variant from non-automotive versions and confirms compliance with automotive reliability standards including temperature cycling, highly accelerated life testing (HALT), and electrostatic discharge (ESD) per AEC-Q101. The "_A/H" further specifies packaging in 7″ tape-and-reel format.
How does the clamping voltage of TPSMB10AHE3_A/H compare to its breakdown voltage?
The TPSMB10AHE3_A/H clamps at 14.5 V when subjected to its rated 41.4 A peak pulse current (IPPM), yielding a clamping ratio (VC/VBR) of approximately 1.45. This tight ratio-enabled by low incremental surge resistance-ensures downstream components experience minimal overvoltage stress, especially critical for protecting 3.3 V and 5 V microcontroller I/O pins and MOSFET gate oxides.
Can TPSMB10AHE3_A/H be used in bidirectional configurations?
No, TPSMB10AHE3_A/H is unidirectional only, as explicitly stated in the Vishay datasheet. Its internal structure and polarity marking (cathode band) support clamping only in the reverse direction. For bidirectional transient suppression, a separate device such as the SMBJ10CA or dual-series configuration would be required-TPSMB10AHE3_A/H must not be substituted in bidirectional applications without circuit redesign.
