Product details
Overview
TPSMC16AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 66.7 A peak pulse current (IPPM), and clamps to 22.5 V at rated surge. It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power systems.
For engineers reviewing the TPSMC16AHE3_B/I datasheet, TPSMC16AHE3_B/I pinout, TPSMC16AHE3_B/I application, or TPSMC16AHE3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C maximum junction temperature, unidirectional polarity, low clamping ratio (VC/VBR = 1.41), and RoHS-compliant matte tin-plated terminals solderable per J-STD-002.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and fast response to transient events. Its junction passivation enables reliable operation up to TJ = 185 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
The device operates exclusively in unidirectional mode with cathode-band polarity marking, delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions, and exhibits low incremental surge resistance for effective clamping during ESD and load-switching transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Lower peak pulse power (600 W), same VBR range and SMC-compatible SMB (DO-214AA) package | Not AEC-Q101 qualified; limited to commercial/industrial use below 150 °C | Select when cost sensitivity outweighs automotive qualification and 1500 W surge headroom |
| TPSMC16AHE3_B/H | Identical electrical specs and qualification; differs only in tape-and-reel packaging (7″ vs. 13″ reel, 850 vs. 3500 units) | No functional or application difference; identical performance and mounting | Select for smaller batch prototyping or space-constrained SMT feeders |
Compared with SMBJ16A and TPSMC16AHE3_B/H, the TPSMC16AHE3_B/I offers full AEC-Q101 compliance and 2.5× higher pulse power than SMBJ16A, while sharing identical protection characteristics with TPSMC16AHE3_B/H-making it optimal for high-volume automotive production requiring 13″ reel logistics.

FAQ
What is the breakdown voltage tolerance for TPSMC16AHE3_B/I?
The TPSMC16AHE3_B/I has a specified breakdown voltage (VBR) range of 15.2 V (min) to 16.8 V (max) at 1 mA test current, with 16.0 V nominal. This ±5% tolerance ensures predictable clamping onset while accommodating process variation and temperature drift, making it suitable for designs requiring tight overvoltage margins without overspecifying downstream components.
Is TPSMC16AHE3_B/I compatible with lead-free reflow processes?
Yes, TPSMC16AHE3_B/I meets J-STD-020 MSL Level 1 and supports peak reflow temperatures up to 260 °C, fully compliant with standard lead-free soldering profiles. Its matte tin-plated terminals are solderable per J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing-ensuring robust interconnect reliability in high-volume SMT assembly.
Does TPSMC16AHE3_B/I have automotive qualification?
Yes, TPSMC16AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation (Document Number 88407). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for under-hood and safety-critical automotive subsystems.
What is the maximum clamping voltage of TPSMC16AHE3_B/I at rated surge current?
The maximum clamping voltage (VC) of TPSMC16AHE3_B/I is 22.5 V at its rated peak pulse current (IPPM) of 66.7 A, measured under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during worst-case transient events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the thermal performance of TPSMC16AHE3_B/I compare to standard TVS diodes?
TPSMC16AHE3_B/I supports a maximum junction temperature of +185 °C-significantly higher than typical TVS diodes rated to +150 °C. This extended range enables operation in high-ambient environments such as engine compartments or sealed industrial enclosures, and improves long-term reliability under sustained power dissipation or repeated surge events without thermal runaway.
