Product details
Overview
TPSMB16A-1BHE3/5BT from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching transients and lightning-induced surges on power rails and signal lines. It features a 16.0 V nominal breakdown voltage (VBR), 13.6 V maximum stand-off voltage (VWM), 22.5 V clamping voltage at 26.7 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB16A-1BHE3/5BT datasheet, TPSMB16A-1BHE3/5BT pinout, TPSMB16A-1BHE3/5BT application, or TPSMB16A-1BHE3/5BT equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, TJ = 185 °C thermal rating, and clamping performance under repetitive 10/1000 µs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable breakdown characteristics across temperature and high reliability under automotive-grade thermal cycling. Its unidirectional configuration enables forward-biased conduction only during reverse overvoltage events, with low incremental surge resistance ensuring minimal voltage overshoot during fast transients.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 0.078 %/°C temperature coefficient of VBR, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - confirming suitability for automated SMT assembly in high-volume automotive and industrial PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable triggering above system operating voltage while maintaining margin against false clamping |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1 µA, compatible with 12 V nominal automotive systems |
| VC @ IPPM | 22.5 V - clamping voltage at 26.7 A peak pulse current, limiting downstream IC stress during ISO 7637-2 pulse 1/2a events |
| PPPM | 600 W - peak pulse power handling capability with 10/1000 µs waveform, supporting robust protection in engine control units |
| TJ max. | +185 °C - extended junction temperature rating enabling placement near high-power components without derating |
| Polarity | Unidirectional - provides reverse-biased surge suppression only; requires correct orientation relative to protected rail |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.220" x 0.130" footprint and matte tin-plated leads |
Pinout & Package
TPSMB16A-1BHE3/5BT is housed in an SMB (DO-214AA) plastic package with cathode indicated by a color band. The device has two terminals: anode and cathode - no internal circuitry or additional pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current return path | Connected to protected line; conducts during overvoltage to shunt energy to ground or lower-potential rail |
| Anode | Reference terminal | Typically tied to ground or common return; completes clamping path when cathode voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain and body electronics per stress test requirements |
| Junction passivation | Stable VBR drift < ±5 % over lifetime under 150 °C bias temperature and humidity exposure |
| MSL Level 1 | Zero floor life limitation; supports unlimited storage and standard reflow without baking preconditioning |
| Low clamping ratio (VC/VBR) | 1.41 - tight ratio minimizes overvoltage margin required for downstream component withstand ratings |
| Halogen-free option available | HM3 suffix variant meets IEC 61249-2-21; HE3 suffix is RoHS-compliant but not halogen-free |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Use Scenario: Adding secondary surge immunity to USB VBUS lines in portable speakers and smart home hubs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBUS and GND to suppress positive transients from hot-plug or adapter faults. Use Value: 600 W pulse rating handles multiple 10/1000 µs surges without degradation, extending field life beyond 100,000 connect/disconnect cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VBR range (15.2–16.8 V), but lower PPPM = 400 W and smaller SMA package (DO-214AC); TJ max. = 150 °C | Limited to non-automotive industrial use due to lack of AEC-Q101 qualification and reduced thermal margin | Select when board space is constrained and surge energy is ≤400 W; verify layout thermal relief for sustained 125 °C ambient |
| TPSMB16CA | Bi-directional variant with identical VBR, VC, and PPPM; adds symmetric clamping for AC-coupled or bidirectional signal lines | Required for RS-485, CAN, or audio lines where both polarities must be suppressed | Choose only if bidirectional protection is needed; otherwise, TPSMB16A-1BHE3/5BT offers lower capacitance and tighter VC for DC rails |
Compared with SMAJ16A and TPSMB16CA, the TPSMB16A-1BHE3/5BT delivers higher thermal resilience (185 °C vs. 150 °C), automotive qualification, and superior surge handling (600 W), making it optimal for under-hood and high-reliability power rail protection where long-term stability is critical.

FAQ
What is the AEC-Q101 qualification status of the TPSMB16A-1BHE3/5BT?
The TPSMB16A-1BHE3/5BT carries full AEC-Q101 qualification, confirmed by Vishay's documentation for the HE3 suffix variant. This includes stress testing for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating its use in automotive powertrain and chassis modules where reliability is mission-critical. The TPSMB16A-1BHE3/5BT meets all requirements without derating.
Does the TPSMB16A-1BHE3/5BT have a bidirectional version?
Yes - the bidirectional counterpart is the TPSMB16CA, which shares identical electrical ratings (VBR, VC, PPPM) but clamps surges of either polarity. The TPSMB16A-1BHE3/5BT is strictly unidirectional and must be oriented with cathode toward the protected line. Using the unidirectional TPSMB16A-1BHE3/5BT in place of TPSMB16CA will fail to suppress negative transients.
What is the maximum clamping voltage of the TPSMB16A-1BHE3/5BT at rated peak pulse current?
The TPSMB16A-1BHE3/5BT has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A, measured using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Can the TPSMB16A-1BHE3/5BT be used in DC power supply designs with 24 V nominal input?
No - the TPSMB16A-1BHE3/5BT has a maximum stand-off voltage (VWM) of 13.6 V, making it unsuitable for direct use on 24 V rails. For 24 V systems, select TPSMB27A (VWM = 23.1 V) or TPSMB30A (VWM = 25.6 V). Using TPSMB16A-1BHE3/5BT on 24 V would cause excessive leakage and premature conduction.
What is the thermal resistance (RθJA) of the TPSMB16A-1BHE3/5BT in standard PCB layout?
Vishay does not publish a specific RθJA value for the TPSMB16A-1BHE3/5BT in the datasheet. Thermal performance depends entirely on PCB copper pad area and layout - the datasheet specifies ratings assume 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads at each terminal. Derating curves in Figure 2 must be applied for ambient temperatures above 25 °C when using this layout.
