Product details
Overview
TPSMB13A-1BHE3/5BT from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V maximum stand-off voltage (VWM), 18.2 V clamping voltage at 33 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - ideal for automotive power rail protection in engine control units and body electronics.
For engineers reviewing the TPSMB13A-1BHE3/5BT datasheet, TPSMB13A-1BHE3/5BT pinout, TPSMB13A-1BHE3/5BT application, or TPSMB13A-1BHE3/5BT equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, TJ = 185 °C capability, and clamping performance under repetitive 10/1000 µs surge conditions.
Technical Context
The TPSMB13A-1BHE3/5BT employs passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation. Its unidirectional architecture provides low clamping voltage (18.2 V at IPPM) and fast response time to protect downstream ICs and MOSFETs from transient overvoltage events.
Rated for 600 W peak pulse power per 10/1000 µs waveform and 75 A non-repetitive forward surge current (8.3 ms half-sine), it meets MSL Level 1 moisture sensitivity and supports reflow soldering up to 260 °C peak temperature - confirming suitability for automated SMT assembly in automotive-grade production.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same SMB package and 13 V VBR, but rated for 600 W with lower clamping voltage (17.0 V at 34.4 A); not AEC-Q101 qualified | Preferred for cost-sensitive industrial designs where automotive qualification is unnecessary | Select SMBJ13A if AEC-Q101 is not required and tighter clamping is prioritized over high-temperature reliability |
| SMCJ13A | Larger SMC (DO-214AB) package; same 13 V VBR and 600 W rating but higher IPPM (43.3 A) and lower VC (21.5 V); AEC-Q101 available only in HM3 variant | Suitable where board space allows larger footprint and higher surge margin is needed | Choose SMCJ13A when PCB layout permits larger package and higher single-pulse robustness is critical |
Compared with SMBJ13A and SMCJ13A, the TPSMB13A-1BHE3/5BT uniquely combines AEC-Q101 qualification, +185 °C operation, and SMB footprint - making it the optimal choice for space-constrained automotive modules requiring long-term reliability under thermal stress.

FAQ
What is the exact breakdown voltage range for TPSMB13A-1BHE3/5BT?
The TPSMB13A-1BHE3/5BT has a specified breakdown voltage (VBR) range of 12.4 V (minimum) to 13.7 V (maximum) at 1 mA test current, with a nominal value of 13.0 V. This range is measured per ANSI/IEEE C62.35 standards and confirmed in Vishay's official datasheet revision 23-Jan-2024 (Document Number: 88406). The TPSMB13A-1BHE3/5BT maintains this specification across its full operating temperature range.
Is TPSMB13A-1BHE3/5BT AEC-Q101 qualified?
Yes, the TPSMB13A-1BHE3/5BT is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "FEATURES" and confirmed in the ordering information section. The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, validated for automotive applications including under-hood and body electronics. This qualification applies directly to the TPSMB13A-1BHE3/5BT part number.
What is the clamping voltage of TPSMB13A-1BHE3/5BT at its rated peak pulse current?
The TPSMB13A-1BHE3/5BT exhibits a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPPM) of 33 A, tested using the standard 10/1000 µs waveform. This value is published in the Electrical Characteristics table of the Vishay datasheet and reflects worst-case clamping performance under surge conditions - a critical parameter for ensuring downstream ICs remain within safe operating voltage limits.
Does TPSMB13A-1BHE3/5BT support lead-free reflow soldering?
Yes, the TPSMB13A-1BHE3/5BT supports lead-free reflow soldering with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL Level 1 requirements. Its matte tin-plated terminals are solderable per J-STD-002 and JESD 22-B102, and the device passes JESD 201 Class 2 whisker testing - all confirmed in the Mechanical Data section of the Vishay datasheet for TPSMB13A-1BHE3/5BT.
What is the maximum operating junction temperature for TPSMB13A-1BHE3/5BT?
The TPSMB13A-1BHE3/5BT has a maximum operating junction temperature (TJ) of +185 °C, enabling reliable operation in high-temperature automotive and industrial environments. This rating is specified in both the Maximum Ratings and Primary Characteristics tables of the Vishay datasheet and is integral to the device's AEC-Q101 qualification - a key differentiator versus standard SMB-format TVS diodes.
