Product details
Overview
TPSMB13HE3/5BT 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), 18.2 V maximum clamping voltage at 33 A, and operates up to +185 °C junction temperature - suitable for automotive power supply protection in engine control units and body electronics.
For engineers reviewing the TPSMB13HE3/5BT datasheet, TPSMB13HE3/5BT pinout, TPSMB13HE3/5BT application, or TPSMB13HE3/5BT equivalent, key selection criteria include its unidirectional polarity, SMB (DO-214AA) package compatibility with high-reliability PCB layouts, AEC-Q101 qualification status, and verified clamping performance under repetitive 0.01% duty cycle surge conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable breakdown characteristics across -65 °C to +185 °C operating range. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD and inductive kickback events before sensitive downstream ICs are damaged.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits only 2 µA maximum reverse leakage at VWM, ensuring minimal standby power loss in always-on automotive modules. Its MSL Level 1 rating supports lead-free reflow without popcorn cracking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - ensures reliable conduction onset above normal rail voltage while avoiding false triggering during load dump or cold-crank dips |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 2 µA, compatible with 12 V automotive systems |
| VC @ IPPM | 18.2 V - clamps 33 A surge to safe level for 5 V or 3.3 V logic interfaces downstream of LDOs or DC-DC converters |
| PPPM | 600 W - sustains 10/1000 µs transients common in ISO 7637-2 Pulse 1 & 2a testing without degradation |
| TJ max. | +185 °C - enables placement near hot components (e.g., power MOSFETs, motor drivers) without derating |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation toward protected rail |
| Package | SMB (DO-214AA) - industry-standard footprint with 5.0 mm × 5.0 mm copper pad requirement for thermal dissipation |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, cathode indicated by band. Compliant with J-STD-002 solderability and JESD 22-B102 whisker testing (Class 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode of internal PN junction | Connected to protected line (e.g., 12 V rail); conducts when transient exceeds VBR, shunting current to ground |
| Anode | Cathode of internal PN junction | Connected to system ground; provides low-impedance return path for surge current during clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTOL, TC, HTRB, and ESD - eliminates need for additional qualification by Tier 1 suppliers |
| Junction passivation | Stabilizes VBR over temperature and lifetime; αT = 0.072 %/°C enables accurate clamping prediction across full operating range |
| MSL Level 1 | Supports single-pass lead-free reflow at 260 °C peak without moisture-induced failure - reduces manufacturing yield risk |
| Low clamping ratio (VC/VBR) | 1.40 - minimizes overvoltage stress on downstream components compared to higher-ratio TVS devices |
| 75 A IFSM | Withstands repeated cranking surges and load-dump events without bond wire fusing or junction degradation |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 3a/b (line impedance transients). IC Role / Device Role / Timing Role: Primary clamping element placed between power input and bulk capacitor, conducting within <1 ns to limit voltage excursion.

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 smaller SMA package (DO-214AC); TJ max = +150 °C | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 1 in automotive; not AEC-Q101 qualified | Select when cost or board space is critical and surge energy remains below 400 W capability. |
| SMCJ13A | Higher PPPM = 1500 W, same SMB package, but larger die; VC = 21.2 V at 71.5 A; TJ max = +175 °C | Better for high-energy lightning surges (IEC 61000-4-5), but higher clamping voltage may stress downstream 12 V-rated ICs | Choose when protecting against direct lightning coupling or long-line induced surges where 21.2 V clamping is acceptable. |
Compared with SMAJ13A and SMCJ13A, the TPSMB13HE3/5BT delivers optimal balance of AEC-Q101 compliance, 600 W surge capacity, 18.2 V clamping, and +185 °C operation - making it the preferred choice for space-constrained, high-temperature automotive and industrial power rail protection where reliability and thermal margin are critical.

FAQ
What is the AEC-Q101 qualification status of the TPSMB13HE3/5BT?
The TPSMB13HE3/5BT carries full AEC-Q101 qualification per the Vishay datasheet (Document Number: 88406, Revision: 23-Jan-2024). This includes stress testing for high-temperature operating life, temperature cycling, highly accelerated stress testing, and ESD. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, confirming suitability for automotive powertrain and chassis applications without further qualification by the end user.
Does the TPSMB13HE3/5BT support lead-free reflow soldering?
Yes, the TPSMB13HE3/5BT meets MSL Level 1 per J-STD-020 and is rated for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 Class 2 whisker testing, ensuring reliable solder joint formation and long-term interconnect integrity in automated assembly processes.
What is the maximum clamping voltage of the TPSMB13HE3/5BT at rated surge current?
The TPSMB13HE3/5BT has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPPM) of 33 A, measured using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream IC overvoltage margin analysis in designs such as automotive body control modules.
How does the TPSMB13HE3/5BT differ from the TPSMB13A base part number?
The TPSMB13HE3/5BT is the AEC-Q101 qualified, RoHS-compliant, and halogen-free variant of the TPSMB13A. The "HE3" suffix indicates compliance with automotive reliability standards and environmental regulations, while "/5BT" denotes packaging in 7" tape-and-reel (500 pcs/reel). Electrically and thermally, the TPSMB13HE3/5BT matches the TPSMB13A specifications - including VBR, VC, and PPPM - but adds validated automotive-grade process controls and traceability.
Can the TPSMB13HE3/5BT be used in bidirectional protection configurations?
No, the TPSMB13HE3/5BT is unidirectional only, as confirmed in the Vishay datasheet under FEATURES and ELECTRICAL CHARACTERISTICS. It conducts only for positive transients relative to ground. For bidirectional protection (e.g., AC lines or data buses), a separate bidirectional TVS such as the SMBJ13CA must be selected - the TPSMB13HE3/5BT cannot be substituted without circuit redesign and polarity verification.
