Product details
Overview
TPSMB13AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 18.2 V maximum 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.
For engineers reviewing the TPSMB13AHE3_A/H datasheet, TPSMB13AHE3_A/H pinout, TPSMB13AHE3_A/H application, or TPSMB13AHE3_A/H equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, SMB package mechanical data, and real-world clamping performance under repetitive surge conditions.
Technical Context
The TPSMB13AHE3_A/H uses passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its unidirectional polarity enables robust forward conduction during overvoltage events while maintaining tight VBR tolerance (12.4–13.7 V at 1 mA) and low leakage (<2 µA at VWM = 11.1 V, TA = 25 °C).
Designed for automotive-grade reliability, it meets AEC-Q101 qualification, MSL Level 1 (260 °C reflow), and JESD201 Class 2 whisker resistance. The device sustains 75 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a +0.072 %/°C temperature coefficient of VBR, enabling predictable clamping across -65 °C to +185 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 / 13.0 / 13.7 V at 1 mA - ensures reliable turn-on before downstream IC damage threshold |
| VWM | 11.1 V - maximum continuous reverse voltage without significant leakage |
| VC @ IPPM | 18.2 V at 33 A (10/1000 µs) - defines worst-case clamped voltage seen by protected circuit |
| PPPM | 600 W - supports high-energy transients like load dump or inductive switching |
| TJ max. | +185 °C - enables placement near hot components (e.g., power MOSFETs, engine control units) |
| IR @ VWM | <2 µA at 25 °C - minimizes standby power loss in battery-critical systems |

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontrollers and CAN transceivers from load dump and jump-start surges in vehicle body control modules. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between power rail and chassis ground to clamp transients above 13.7 V. Use Value: Limits voltage to ≤18.2 V during 33 A surges, preventing latch-up or gate oxide rupture in 20 V-rated automotive MCUs. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) from ESD and field-induced transients in factory automation sensors. IC Role / Device Role / Timing Role: Low-leakage TVS mounted across signal and return paths to absorb ±8 kV contact ESD per IEC 61000-4-2. Use Value: Sub-2 µA leakage at 11.1 V preserves loop accuracy; fast response time prevents sensor ADC saturation during fast-rising transients. |
| Telecom DC Power Input Protection | Computer Peripheral USB VBUS Line Protection |
Use Scenario: Securing 48 V PoE-powered switches and base station radios against lightning-induced surges on DC input terminals. IC Role / Device Role / Timing Role: Primary clamping device in series with upstream fuse, rated for 600 W 10/1000 µs waveform per IEEE 802.3bt. Use Value: Withstands 1000 V open-circuit surge tests when paired with appropriate impedance; TJ = 185 °C rating supports sealed outdoor enclosures. | Use Scenario: Adding secondary overvoltage protection on USB 2.0/3.0 host ports where VBUS may experience hot-plug overshoot or adapter fault conditions. IC Role / Device Role / Timing Role: Fast-response TVS placed between VBUS and GND to clamp excursions beyond 5.5 V without affecting normal 5 V operation. Use Value: 11.1 V VWM avoids false triggering during 5 V tolerance margins; SMB footprint allows compact placement near USB connector. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | 400 W PPPM, same VBR range but lower clamping (18.2 V → 21.2 V at 23.3 A), SMA package (smaller thermal mass) | Limited to lower-energy transients; not AEC-Q101 qualified | Select for cost-sensitive consumer designs where automotive qualification and 600 W capability are unnecessary |
| SMCJ13A | 1500 W PPPM, same VBR, higher IPPM (102 A), larger SMC package (DO-214AB) | Required for ISO 16750-2 long-duration surges; adds PCB area and thermal inertia | Choose when system-level testing demands >1000 W surge handling or extended thermal dissipation is needed |
Compared with SMAJ13A and SMCJ13A, the TPSMB13AHE3_A/H delivers optimal balance of AEC-Q101 compliance, 600 W surge capacity, SMB footprint density, and +185 °C operation - making it the preferred choice for space-constrained automotive and industrial power rail protection where reliability and thermal resilience are critical.

FAQ
What is the maximum clamping voltage of the TPSMB13AHE3_A/H under standard test conditions?
The TPSMB13AHE3_A/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 33 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C with specified mounting conditions (0.2" × 0.2" copper pads), and represents the upper limit of voltage imposed on the protected circuit during transient events.
Is the TPSMB13AHE3_A/H qualified for automotive applications?
Yes, the TPSMB13AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101-qualified construction. It undergoes rigorous stress testing including high-temperature operating life, temperature cycling, and humidity bias for use in automotive powertrain, body, and infotainment systems.
What does the "HE3" suffix indicate in TPSMB13AHE3_A/H?
The "HE3" suffix in TPSMB13AHE3_A/H identifies a RoHS-compliant, AEC-Q101-qualified version with matte tin-plated leads, JESD201 Class 2 whisker resistance, and MSL Level 1 rating. The "_A/H" denotes revision A in 7" tape-and-reel packaging (750 units per reel), per Vishay's official ordering information table.
How does the TPSMB13AHE3_A/H perform at elevated temperatures?
The TPSMB13AHE3_A/H maintains full functionality up to +185 °C junction temperature. Its VBR shifts predictably with temperature (+0.072 %/°C), and pulse power derates linearly above 25 °C per Figure 2 in the datasheet - enabling accurate thermal design for under-hood or enclosed industrial environments where ambient exceeds 125 °C.
Can the TPSMB13AHE3_A/H replace older SMB-format TVS diodes like P6SMB13A?
The TPSMB13AHE3_A/H is not a direct drop-in replacement for P6SMB13A due to differences in thermal design, surge lifetime, and qualification status. While both share SMB package and similar VBR, the TPSMB13AHE3_A/H offers superior 185 °C rating, AEC-Q101 qualification, and tighter VBR tolerance - requiring validation of board-level thermal performance and system-level surge testing before substitution.
