Product details
Overview
TPSMB13AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive load switching transients and lightning-induced surges on signal lines and power rails. It features 13.0 V nominal breakdown voltage (VBR), 11.1 V 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, with AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMB13AHE3_A/I datasheet, TPSMB13AHE3_A/I pinout, TPSMB13AHE3_A/I application, or TPSMB13AHE3_A/I equivalent, this page delivers verified electrical parameters, thermal limits (TJ = –65 °C to +185 °C), mechanical package data, real-world clamping behavior, and qualified automotive alternatives - all confirmed against Vishay Document #88406 (Rev. 23-Jan-2024).
Technical Context
The TPSMB13AHE3_A/I operates as a unidirectional avalanche diode, leveraging passivated anisotropic rectifier technology to achieve stable breakdown under fast-rising transients. Its 10/1000 µs waveform response ensures reliable clamping of inductive kickback and ESD events while maintaining low incremental surge resistance and sub-nanosecond response time.
Rated for TJ max. = 185 °C and MSL Level 1 (260 °C reflow), it supports high-reliability automotive and industrial environments. The device exhibits a positive temperature coefficient of VBR (αT = 0.072 %/°C), enabling predictable voltage drift across operating temperature ranges without derating ambiguity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines precise avalanche initiation threshold at 1 mA test current, critical for margin-based overvoltage protection design |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 2 µA, sets safe operating ceiling for normal-mode signals |
| VC @ IPPM | 18.2 V - clamped voltage during 33 A 10/1000 µs surge, directly determines protected IC's voltage stress limit |
| PPPM | 600 W - peak pulse power handling capability under standardized waveform, defines transient energy absorption capacity |
| IFSM | 75 A - 8.3 ms half-sine surge current rating, validates robustness against repetitive motor-switching events |
| TJ range | –65 °C to +185 °C - extended junction temperature window enables under-hood automotive deployment without derating penalties |
| αT | 0.072 %/°C - temperature coefficient of VBR, allows accurate VBR recalculations across ambient conditions using documented formula |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified. Cathode indicated by color band. Dimensions per Vishay outline drawing: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H), with 5.0 mm × 5.0 mm copper pad requirement per terminal for thermal derating compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during forward conduction; reference node for reverse-biased clamping | Connected to protected circuit ground or low-side return path; establishes reference for VWM and VC measurements |
| Cathode | Transient voltage sensing node; avalanche initiation point | Connected to line under protection (e.g., CAN_H, LIN, sensor supply); absorbs surge energy into ground via anode |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables asymmetric protection on DC-biased lines (e.g., 12 V power rails, CAN bus), eliminating need for series blocking components |
| AEC-Q101 qualification | Validates reliability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| 185 °C junction rating | Supports operation in high-temperature zones (e.g., near powertrain modules) without thermal shutdown or parameter drift |
| MSL Level 1 (260 °C) | Permits standard lead-free reflow assembly without moisture sensitivity concerns or baking requirements |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during surge events, reducing risk of downstream IC latch-up or gate oxide damage |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same SMB package, identical VBR (12.4–13.7 V), but not AEC-Q101 qualified; lower TJ max. (150 °C) | Limited to commercial/industrial use; unsuitable for under-hood automotive deployments requiring 185 °C operation | Select SMBJ13A only when automotive qualification and extended temperature range are not required - reduces cost where reliability margins allow. |
| TPSMB13AHM3_A/I | Halogen-free variant of same base device; identical electrical specs, VBR, VC, PPPM, and AEC-Q101 qualification | No functional difference; selected solely to meet halogen-free material compliance (e.g., IPC-1752A Tier 2 reporting) | Choose TPSMB13AHM3_A/I when RoHS + halogen-free certification is mandated by OEM or regulatory program - electrically interchangeable. |
Compared with SMBJ13A and TPSMB13AHM3_A/I, the TPSMB13AHE3_A/I provides guaranteed AEC-Q101 qualification and 185 °C operation in a RoHS-compliant, non-halogen-free form - making it the default choice for automotive Tier-1 suppliers requiring traceable qualification evidence and high-temperature resilience without halogen reporting overhead.

FAQ
What is the maximum clamping voltage of the TPSMB13AHE3_A/I at its rated peak pulse current?
The TPSMB13AHE3_A/I has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 33 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document #88406 and defines the upper voltage limit imposed on protected circuitry during surge events. The TPSMB13AHE3_A/I maintains this clamping performance across its full operating temperature range.
Is the TPSMB13AHE3_A/I suitable for automotive applications?
Yes, the TPSMB13AHE3_A/I is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and chassis-mounted automotive applications including engine control units, body control modules, and ADAS sensor interfaces. Its qualification is explicitly stated in the Vishay datasheet (Document #88406, Rev. 23-Jan-2024) and confirmed by the HE3 suffix designation.
What does the "HE3" suffix indicate in TPSMB13AHE3_A/I?
Within the TPSMB series, the "HE3" suffix denotes a RoHS-compliant, AEC-Q101-qualified version with matte tin-plated leads and JESD201 Class 2 whisker resistance. The "A/I" portion specifies packaging: 13-inch tape-and-reel, 3200 units per reel. This distinguishes it from HM3 (halogen-free) and non-qualified variants, confirming its suitability for automotive production.
How does the TPSMB13AHE3_A/I compare to bidirectional TVS diodes in surge protection?
The TPSMB13AHE3_A/I is unidirectional and optimized for DC-biased lines like 12 V power rails or CAN bus, offering tighter VWM/VBR ratios and lower leakage than bidirectional equivalents. Unlike bidirectional TVS devices, it does not protect against reverse-polarity faults - its design assumes fixed polarity, which improves clamping precision and reduces capacitance on signal lines. The TPSMB13AHE3_A/I is not intended for AC line protection.
What is the thermal derating behavior of the TPSMB13AHE3_A/I above 25 °C ambient?
The TPSMB13AHE3_A/I follows the derating curve in Figure 2 of Vishay Document #88406: peak pulse power decreases linearly from 600 W at 25 °C to zero at 185 °C junction temperature. At 125 °C case temperature, it retains approximately 65 % of rated PPPM (≈390 W). Derating is based on junction temperature, not ambient, and requires proper PCB copper pad design (0.2" × 0.2" per terminal) to maintain thermal performance. The TPSMB13AHE3_A/I datasheet provides exact derating multipliers.
