Product details
Overview
TPSMB13HE3/52T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and lightning-induced surges on power and signal lines. It features 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 18.2 V maximum clamping voltage at 33 A peak pulse current, and operates up to +185 °C junction temperature - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMB13HE3/52T datasheet, TPSMB13HE3/52T pinout, TPSMB13HE3/52T application, or TPSMB13HE3/52T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 75 A non-repetitive surge current rating, and compatibility with high-reliability PCB layouts requiring robust ESD/EFT immunity per IEC 61000-4-2/4-4.
Technical Context
The TPSMB13HE3/52T employs passivated anisotropic rectifier technology optimized for stable breakdown behavior across temperature extremes. Its 185 °C maximum junction temperature enables operation in under-hood automotive environments and high-power industrial converters where thermal derating of conventional TVS devices limits reliability.
It delivers precise clamping performance with 0.072 %/°C temperature coefficient of VBR, low incremental surge resistance, and fast response time (<1 ns), ensuring consistent overvoltage protection during repetitive 10/1000 µs transients at ≤0.01 % duty cycle - critical for safeguarding MOSFET gate drivers and microcontroller I/O pins against coupled noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines minimum voltage at which device enters avalanche conduction; ensures reliable triggering above system operating voltage. |
| VWM | 11.1 V - maximum continuous reverse working voltage; must exceed normal circuit operating voltage to prevent leakage-induced power loss. |
| VC @ IPPM | 18.2 V at 33 A - clamped voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM | 600 W - peak pulse power handling capability; defines energy absorption capacity for transient suppression without failure. |
| IFSM | 75 A - non-repetitive forward surge current rating (8.3 ms half-sine); supports high-energy inductive kickback events. |
| TJ max. | +185 °C - enables use in high-temperature zones such as engine control units and motor drive inverters without thermal shutdown. |
| Polarity | Unidirectional - provides reverse-biased clamping only; requires correct orientation relative to DC bias in power rail applications. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with cathode band marking; compatible with automated SMT assembly and reflow profiles up to 260 °C peak. |
Pinout & Package
TPSMB13HE3/52T uses the SMB (DO-214AA) package: a two-terminal, surface-mount plastic case with molded cathode band indicating terminal polarity. Dimensions are 4.57 mm × 3.94 mm × 2.20 mm (L × W × H), with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | High-side connection point for reverse-biased clamping | Connected to protected line (e.g., 12 V rail); conducts avalanche current when line voltage exceeds VBR. |
| Anode | Low-side reference node | Typically tied to ground or low-impedance return path; completes clamping loop during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - required for under-hood ECUs and ADAS sensors. |
| Junction passivation | Reduces surface leakage and improves long-term stability under high-humidity and high-temperature operating conditions. |
| MSL Level 1 | Zero floor life limitation before reflow; eliminates baking requirements and simplifies manufacturing logistics for high-volume production. |
| Low clamping ratio (VC/VBR) | 1.40 - indicates efficient voltage limiting; minimizes overvoltage margin needed for protected ICs' absolute maximum ratings. |
| 0.072 %/°C αT | Ensures predictable VBR shift over temperature; simplifies design margining for systems operating from -40 °C to +150 °C ambient. |

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 SMB package, 13 V VBR, but rated for 400 W PPPM and not AEC-Q101 qualified; higher VC (21.5 V). | Limited to commercial-grade consumer and industrial equipment without automotive qualification requirements. | Select SMAJ13A only if AEC-Q101 compliance and 600 W surge capacity are not required; verify layout thermal relief for lower power rating. |
| SMCJ13A | Higher-power 1500 W variant in larger SMC (DO-214AB) package; identical VBR and VC, but incompatible footprint and higher cost. | Suitable for high-energy surge environments (e.g., outdoor telecom cabinets) where PCB space allows larger package. | Choose SMCJ13A when system-level surge testing exceeds IEC 61000-4-5 Level 4; avoid if board area or height constraints mandate SMB form factor. |
Compared with SMAJ13A and SMCJ13A, the TPSMB13HE3/52T uniquely balances AEC-Q101 qualification, 600 W surge capability, and SMB footprint - making it optimal for space-constrained automotive modules needing validated reliability without sacrificing clamping performance.

FAQ
What is the exact breakdown voltage range for TPSMB13HE3/52T?
The TPSMB13HE3/52T has a guaranteed breakdown voltage (VBR) range of 12.4 V (minimum) to 13.7 V (maximum) at 1 mA test current, with 13.0 V nominal. This specification is measured per ANSI/IEEE C62.35 and confirmed in Vishay's official datasheet revision 23-Jan-2024 (Document Number: 88406). The TPSMB13HE3/52T maintains this tolerance across its full operating temperature range.
Is TPSMB13HE3/52T AEC-Q101 qualified and what does that cover?
Yes, TPSMB13HE3/52T is AEC-Q101 qualified - verified per the full stress test suite including HTGB, HTRB, TCT, UHAST, and mechanical shock. The HE3 suffix explicitly denotes RoHS-compliant, halogen-free, and AEC-Q101-qualified construction. This qualification confirms suitability for automotive applications such as body control modules and ADAS sensor interfaces where reliability under thermal and vibration stress is critical. The TPSMB13HE3/52T meets these requirements without derating.
What is the maximum clamping voltage of TPSMB13HE3/52T and at what current is it specified?
The maximum clamping voltage (VC) of TPSMB13HE3/52T is 18.2 V, measured at 33 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is guaranteed per datasheet Table "ELECTRICAL CHARACTERISTICS" and reflects worst-case clamping performance under surge conditions. Designers use this parameter to verify that downstream components remain within their absolute maximum voltage ratings during transient events. The TPSMB13HE3/52T achieves this with low incremental resistance and stable thermal response.
Can TPSMB13HE3/52T be used in bidirectional configurations?
No, TPSMB13HE3/52T is unidirectional only - it clamps only in reverse bias and conducts forward current like a standard diode. For bidirectional transient suppression (e.g., AC line or differential data lines), a separate bidirectional TVS such as TPSMB13CA or paired unidirectional devices would be required. The TPSMB13HE3/52T datasheet explicitly states "Available in unidirectional polarity only", and its internal structure lacks symmetrical avalanche characteristics.
What is the moisture sensitivity level (MSL) rating for TPSMB13HE3/52T and how does it affect assembly?
TPSMB13HE3/52T is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60 % RH and requires no dry pack or baking prior to reflow soldering. Its molding compound meets UL 94 V-0, and peak reflow temperature is rated to 260 °C. This eliminates moisture-related popcorning risk and simplifies SMT line logistics - especially important for high-throughput automotive electronics manufacturing where the TPSMB13HE3/52T is commonly deployed.
