Product details
Overview
TPSMB8.2HE3/5BT 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 a 8.2 V breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 49.6 V clamping voltage at 49.6 A peak surge current, and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB8.2HE3/5BT datasheet, TPSMB8.2HE3/5BT pinout, TPSMB8.2HE3/5BT application, or TPSMB8.2HE3/5BT equivalent, this page delivers verified electrical parameters, SMB (DO-214AA) package details, AEC-Q101 qualification status, clamping performance under 10/1000 µs surge, and direct alternatives for overvoltage protection design-in.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and excellent clamping linearity during fast transients. Its unidirectional polarity and 10 mA test current ensure stable VBR measurement per ANSI/IEEE C62.35, with ±5% tolerance (7.79–8.61 V) and +0.056 %/°C temperature coefficient.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine), 3.5 V max forward voltage at 50 A, and meets MSL Level 1 reflow compatibility (260 °C peak). Its cathode-band-marked SMB package supports automated placement and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.79 / 8.20 / 8.61 V at 10 mA - defines precise clamping onset threshold for reliable overvoltage detection |
| VWM | 7.02 V - maximum continuous reverse working voltage before leakage exceeds 100 μA |
| VC @ IPPM | 49.6 V at 49.6 A - clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 600 W - peak pulse power handling capability under standard 10/1000 µs waveform |
| TJ max | +185 °C - enables operation in high-temperature environments including engine control units |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct orientation in circuit |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 0.220" × 0.130" footprint and matte tin leads |
Pinout & Package
SMB (DO-214AA) package: molded plastic case with cathode band marking; terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode of internal PN junction | Connected to protected line; conducts during positive transient to clamp voltage to VC |
| Anode | Cathode of internal PN junction | Typically tied to ground or lower-potential rail; completes clamping path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR drift < ±5% over lifetime and temperature |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and HAST testing per stress conditions |
| MSL Level 1 | Zero moisture sensitivity - supports lead-free reflow up to 260 °C without popcorn effect or delamination |
| Low clamping ratio | VC/VBR ≈ 6.05 - tight clamping margin preserves margin between VWM and VC for robust system design |
| Fast response time | < 1.0 ps intrinsic junction response - clamps transients before propagation to sensitive downstream logic |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | VBR = 8.0–8.89 V (min/typ/max); VC = 12.7 V @ 47.2 A; same SMB package | Lower clamping voltage but 400 W rating - suitable where lower VC is prioritized over surge energy handling | Select when system-level surge testing requires tighter clamping than 49.6 V, and 400 W pulse power suffices. |
| SMCJ8.0A | VBR = 8.0–8.89 V; VC = 12.7 V @ 78.6 A; SMC (DO-214AB) package - 30% larger footprint | Higher 1500 W pulse rating and lower thermal resistance - used where higher single-event energy absorption is required | Choose when protecting high-current bus lines (e.g., CAN FD power domains) needing >600 W dissipation capability. |
Compared with SMBJ8.0A and SMCJ8.0A, the TPSMB8.2HE3/5BT offers balanced 600 W surge handling in the smallest SMB footprint with AEC-Q101 qualification - making it optimal for space-constrained automotive modules where both reliability and board area matter.

FAQ
What is the exact breakdown voltage range for TPSMB8.2HE3/5BT?
The TPSMB8.2HE3/5BT has a guaranteed breakdown voltage range of 7.79 V (minimum) to 8.61 V (maximum) at 10 mA test current, with a nominal value of 8.20 V. This specification is measured per ANSI/IEEE C62.35 and confirmed in Vishay's official datasheet revision 23-Jan-2024 (Document Number: 88406). The TPSMB8.2HE3/5BT maintains this tolerance across its qualified operating temperature range.
Is TPSMB8.2HE3/5BT AEC-Q101 qualified?
Yes, the TPSMB8.2HE3/5BT is AEC-Q101 qualified - explicitly stated in the Vishay datasheet under "FEATURES" and "ORDERING INFORMATION", where HE3 suffix denotes RoHS-compliant and AEC-Q101 qualified construction. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing.
What is the clamping voltage of TPSMB8.2HE3/5BT at its rated surge current?
The TPSMB8.2HE3/5BT clamps to a maximum of 49.6 V at its peak pulse current (IPPM) of 49.6 A under the standard 10/1000 µs waveform. This value is specified in the Electrical Characteristics table and reflects worst-case clamping performance at TA = 25 °C. The TPSMB8.2HE3/5BT maintains this clamping behavior with minimal derating up to +125 °C ambient.
Does TPSMB8.2HE3/5BT support lead-free reflow soldering?
Yes, the TPSMB8.2HE3/5BT meets MSL Level 1 per J-STD-020 and supports lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and the HE3 suffix confirms full compliance with JEDEC moisture sensitivity and whisker resistance (JESD 201 Class 2).
What package type does TPSMB8.2HE3/5BT use, and what are its key mechanical dimensions?
The TPSMB8.2HE3/5BT uses the SMB (DO-214AA) package: overall dimensions are 4.57 mm × 3.94 mm × 2.29 mm (L × W × H), with a 5.59 mm × 3.30 mm mounting pad layout. The cathode is marked by a visible band, and the case complies with UL 94 V-0 flammability rating - all confirmed in the Vishay mechanical drawings (Document Number: 88406, Page 4).
