Product details
Overview
TPSMB7.5HE3/52T from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 7.5 V nominal breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 11.3 V maximum clamping voltage at 53.1 A, and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB7.5HE3/52T datasheet, TPSMB7.5HE3/52T pinout, TPSMB7.5HE3/52T application, or TPSMB7.5HE3/52T equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, TJ = 185 °C thermal rating, and clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable breakdown behavior across temperature and high reliability under repetitive surge stress. Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow soldering at 260 °C peak and extended operation in under-hood automotive environments.
The device exhibits low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of fast-rising transients before downstream ICs or MOSFETs are damaged. Clamping occurs at 11.3 V when subjected to its rated 53.1 A peak pulse current (10/1000 µs waveform), with <500 µA reverse leakage at VWM = 6.4 V and 25 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Lower PPPM (400 W), same SMB package, VBR = 7.22–7.98 V, no AEC-Q101 qualification | Rated for commercial/industrial use only; not validated for automotive temperature cycling or humidity testing | Select SMAJ7.5A only for cost-sensitive non-automotive designs where 400 W surge margin suffices |
| TPSMB7.5AHM3/52T | Identical electrical specs; halogen-free molding compound and JESD201 Class 2 whisker resistance - same AEC-Q101 qualification | Required where RoHS + halogen-free compliance is mandated (e.g., EU automotive Tier 1 BOMs) | Choose TPSMB7.5AHM3/52T when material compliance documentation (e.g., IEC 61249-2-21) is contractually required |
Compared with SMAJ7.5A and TPSMB7.5AHM3/52T, the TPSMB7.5HE3/52T provides AEC-Q101 qualification and RoHS compliance in a 600 W platform, making it the default choice for automotive power rail protection where both reliability and regulatory alignment are mandatory.

FAQ
What is the maximum clamping voltage of the TPSMB7.5HE3/52T under rated surge conditions?
The TPSMB7.5HE3/52T clamps to a maximum of 11.3 V when subjected to its rated 53.1 A peak pulse current (10/1000 µs waveform). This value is measured at the device terminals under standardized test conditions and defines the highest voltage the protected circuit will experience during a full-power transient event. The TPSMB7.5HE3/52T maintains this clamping performance across its full operating temperature range, supporting robust design margins in automotive and industrial systems.
Is the TPSMB7.5HE3/52T qualified for automotive applications?
Yes, the TPSMB7.5HE3/52T is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3". This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TCT), and unbiased highly accelerated stress test (UHAST). The TPSMB7.5HE3/52T is approved for use in automotive subsystems such as body electronics, infotainment power supplies, and sensor interfaces where reliability under thermal and electrical stress is mandatory.
What does the "HE3" suffix indicate in TPSMB7.5HE3/52T?
The "HE3" suffix in TPSMB7.5HE3/52T denotes RoHS-compliant construction and AEC-Q101 qualification. It specifies that the device uses lead-free matte tin plating, meets JESD201 Class 2 whisker resistance, and is manufactured under Vishay's automotive-grade process controls. The "52T" denotes tape-and-reel packaging in 7" diameter reels (750 units per reel), per Vishay's preferred ordering format. This suffix distinguishes it from non-automotive variants like TPSMB7.5A and halogen-free alternatives such as TPSMB7.5AHM3/52T.
Can the TPSMB7.5HE3/52T replace the TPSMB7.5A in existing designs?
Yes, the TPSMB7.5HE3/52T is a direct replacement for TPSMB7.5A in terms of electrical characteristics, package dimensions, and pinout - both use SMB (DO-214AA) and share identical VBR, VWM, VC, and PPPM. However, the TPSMB7.5HE3/52T adds AEC-Q101 qualification and RoHS compliance, making it suitable for automotive upgrades. No PCB changes are required, but designers should verify that the higher thermal rating (185 °C vs. standard 150 °C) aligns with system-level thermal modeling.
What is the reverse leakage current of the TPSMB7.5HE3/52T at its stand-off voltage?
At VWM = 6.4 V and TA = 25 °C, the TPSMB7.5HE3/52T exhibits a maximum reverse leakage current (IR) of 250 µA. At elevated temperature (TJ = 150 °C), leakage increases to a maximum of 500 µA under the same voltage. These values are specified in Vishay's Electrical Characteristics table and confirm minimal standby power loss and negligible impact on high-impedance signal paths - critical for precision sensor front-ends and battery-powered systems.
