Product details
Overview
TPSMB13AHE3/52T from Vishay General Semiconductor is a unidirectional surface-mount 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), 600 W peak pulse power (10/1000 µs), 33 A peak pulse current (IPPM), and 18.2 V maximum clamping voltage (VC) at IPPM, enabling robust protection of MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the TPSMB13AHE3/52T datasheet, TPSMB13AHE3/52T pinout, TPSMB13AHE3/52T application, or TPSMB13AHE3/52T equivalent, key selection criteria include its AEC-Q101 qualification, TJ = 185 °C operation, SMB (DO-214AA) package compatibility, unidirectional polarity, and verified clamping performance under repetitive 0.01% duty-cycle surge conditions.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR = 12.4–13.7 V (min–max at IT = 1 mA). Its low incremental surge resistance and fast response time ensure effective suppression of sub-microsecond transients without latch-up or thermal runaway.
Designed for high-reliability environments, it supports continuous operation from –65 °C to +185 °C junction temperature, meets MSL Level 1 per J-STD-020 (260 °C reflow peak), and uses passivated anisotropic rectifier technology to maintain stable VBR drift (αT = 0.072 %/°C) across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 12.4 V – 13.7 V at IT = 1 mA: defines precise avalanche onset window for predictable clamping threshold |
| VWM | 11.1 V max: ensures no conduction during normal 12 V rail operation, minimizing leakage (<2 µA) |
| VC @ IPPM | 18.2 V max at 33 A: limits worst-case voltage seen by downstream ICs during 600 W transient events |
| PPPM | 600 W (10/1000 µs): sustains standardized surge energy without degradation under 0.01% duty cycle |
| IFSM | 75 A (8.3 ms half-sine): withstands non-repetitive inrush or fault currents in power supply inputs |
| TJ max | +185 °C: enables placement near hot components (e.g., power MOSFETs, DC-DC inductors) without derating |
| AEC-Q101 | Qualified: validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: SMB (DO-214AA) - surface-mount, molded plastic case with matte tin-plated leads, UL 94 V-0 rated, 0.220" × 0.130" footprint, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line (e.g., 12 V rail); conducts avalanche current to ground during overvoltage |
| Anode | Reference/return path | Connected to system ground; completes clamping path with minimal inductance for fast response |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage over lifetime and temperature |
| High-temperature capability | TJ = 185 °C rating allows direct placement on engine-control PCBs or near high-power converters |
| Clamping efficiency | VC/VBR ratio ≤ 1.40 confirms low dynamic impedance for tight voltage limiting during fast transients |
| Reflow compatibility | MSL Level 1 (260 °C peak) supports standard SMT assembly without preconditioning or special handling |
| AEC-Q101 qualification | Validated for automotive applications including powertrain, body electronics, and ADAS sensor interfaces |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface 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 |
|---|---|---|---|
| SMAJ13A | Same VBR range (12.4–13.7 V), but lower PPPM = 400 W and higher VC = 21.2 V; SMA package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for automotive load-dump where 600 W is required | Select TPSMB13AHE3/52T when 600 W surge handling and AEC-Q101 qualification are mandatory |
| SMCJ13A | Higher PPPM = 1500 W, same VBR, but larger SMC (DO-214AB) package; VC = 21.2 V | Better for extreme surges but requires more PCB area and has slower thermal response than SMB | Choose TPSMB13AHE3/52T for space-constrained automotive modules needing optimal power density and proven AEC-Q101 validation |
Compared with SMAJ13A and SMCJ13A, the TPSMB13AHE3/52T delivers superior power density (600 W in SMB), tighter clamping (18.2 V vs. ≥21.2 V), and automotive-qualified reliability-making it the preferred choice for compact, high-temperature, and safety-critical 12 V system protection.

FAQ
What is the exact breakdown voltage range for TPSMB13AHE3/52T?
The TPSMB13AHE3/52T has a guaranteed breakdown voltage (VBR) range of 12.4 V to 13.7 V at test current IT = 1 mA, measured per ANSI/IEEE C62.35. This range ensures reliable avalanche initiation across manufacturing lots and temperature extremes, and is explicitly confirmed in the Vishay datasheet revision 23-Jan-2024 (Document Number: 88406).
Is TPSMB13AHE3/52T qualified for automotive use?
Yes, TPSMB13AHE3/52T is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in the Vishay datasheet. It undergoes full stress testing-including temperature cycling, high-temperature reverse bias (HTRB), and ESD-to meet automotive reliability requirements for powertrain, body, and ADAS systems.
What is the maximum clamping voltage of TPSMB13AHE3/52T during a surge event?
The TPSMB13AHE3/52T exhibits a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPPM) of 33 A, tested with a 10/1000 µs waveform. This value is measured and guaranteed per the datasheet, ensuring downstream components see no more than 18.2 V during standardized surge events.
Does TPSMB13AHE3/52T have unidirectional or bidirectional polarity?
TPSMB13AHE3/52T is unidirectional only, as stated in the Vishay datasheet under FEATURES. Its cathode is marked by a color band, and it conducts only during reverse-biased overvoltage events-making it suitable for DC rail protection where polarity is fixed and forward conduction must be avoided.
What package type does TPSMB13AHE3/52T use, and what are its mounting requirements?
TPSMB13AHE3/52T uses the SMB (DO-214AA) package, with dimensions of 0.220" × 0.130", matte tin-plated leads, and MSL Level 1 rating. It requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for optimal thermal dissipation and surge current handling, per Figure 2 in the Vishay datasheet.
