Product details
Overview
TPSMB10HE3/52T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive and lightning-induced transients on power and signal lines. It features 10 V breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 14.5 A peak pulse current (IPPM), and 41.4 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the TPSMB10HE3/52T datasheet, TPSMB10HE3/52T pinout, TPSMB10HE3/52T application, or TPSMB10HE3/52T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction rating, low clamping ratio (VC/VBR ≈ 4.1), and MSL Level 1 reflow compatibility - critical for high-reliability board-level surge protection design.
Technical Context
The TPSMB10HE3/52T employs passivated anisotropic rectifier technology optimized for stable breakdown behavior under thermal stress. Its 10/1000 µs waveform response delivers consistent 600 W surge handling with <1 ns intrinsic response time and low incremental surge resistance - enabling effective suppression of fast-rising ESD and switching transients.
Rated for operation from –65 °C to +185 °C, it supports automotive under-hood environments and industrial power supplies where thermal derating must be minimized. The device is RoHS-compliant, halogen-free optional (HM3 suffix), and qualified to AEC-Q101 - confirming suitability for automotive electronics without additional qualification effort.
Key Specifications

FAQ
What is the breakdown voltage tolerance of the TPSMB10HE3/52T?
The TPSMB10HE3/52T has a specified breakdown voltage range of 9.5 V to 10.5 V at 1 mA test current, representing a ±5 % tolerance around the nominal 10 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting sensitive 12 V rail components. The TPSMB10HE3/52T maintains this specification under full AEC-Q101 stress testing conditions.
Is the TPSMB10HE3/52T suitable for automotive applications?
Yes, the TPSMB10HE3/52T is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix HE3. It operates reliably from –65 °C to +185 °C, meets MSL Level 1 reflow requirements, and is manufactured in Vishay's certified automotive production lines. The TPSMB10HE3/52T is deployed in engine control modules, body electronics, and ADAS subsystems where transient immunity and long-term stability are mandatory.
What is the maximum clamping voltage of the TPSMB10HE3/52T during a 10/1000 µs surge?
The TPSMB10HE3/52T exhibits a maximum clamping voltage (VC) of 41.4 V when subjected to its rated 14.5 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The TPSMB10HE3/52T achieves this with minimal overshoot due to its low dynamic impedance.
Does the TPSMB10HE3/52T have bidirectional capability?
No, the TPSMB10HE3/52T is strictly unidirectional - it clamps only reverse-biased transients (cathode positive relative to anode). It cannot suppress positive transients on grounded lines or bipolar surges without external circuitry. For bidirectional protection, a separate device such as the TPSMB10CA would be required. The TPSMB10HE3/52T polarity is marked by a cathode band and must be oriented accordingly in PCB layout.
What is the surge current rating of the TPSMB10HE3/52T at elevated temperatures?
The TPSMB10HE3/52T retains 100 % of its 14.5 A peak pulse current (IPPM) rating up to 25 °C ambient, with linear derating beginning above that point per Figure 2 in the datasheet. At 125 °C ambient, the IPPM capability remains ≥10.5 A, and at 150 °C, it sustains ≥8.2 A - enabled by its 185 °C maximum junction temperature rating. This thermal resilience is confirmed in the TPSMB10HE3/52T AEC-Q101 qualification report.
