Product details
Overview
TPSMB16AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode designed for clamping inductive switching transients and lightning-induced surges on power rails and signal lines. It features a 16.0 V nominal breakdown voltage (VBR), 13.6 V maximum working voltage (VWM), 22.5 V clamping voltage at 26.7 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - enabling robust protection in automotive power electronics and industrial sensor interfaces.
For engineers reviewing the TPSMB16AHE3_A/H datasheet, TPSMB16AHE3_A/H pinout, TPSMB16AHE3_A/H application, or TPSMB16AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package compatibility, unidirectional polarity with cathode band marking, low incremental surge resistance, and verified clamping performance under repetitive 0.01% duty cycle stress.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and fast response (<1 ns), delivering precise voltage clamping during ESD and surge events. Its junction design supports 185 °C continuous operation and meets JESD201 Class 2 whisker resistance requirements.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits 0.078 %/°C temperature coefficient of VBR, ensuring predictable breakdown shift across automotive thermal profiles. It is specified for mounting on 5.0 mm × 5.0 mm copper pads per terminal per JEDEC standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VBR (16.0 V typ), but lower PPPM = 400 W and higher VC = 26.0 V at 17.6 A | Limited to lower-energy transients; not AEC-Q101 qualified | Select SMAJ16A only for cost-sensitive consumer applications where 600 W rating and automotive qualification are unnecessary. |
| SMCJ16A | Higher PPPM = 1500 W, same VBR/VC, but larger SMC (DO-214AB) package (0.285" x 0.235") | Requires PCB layout change; better suited for primary-level surge protection in power supplies | Choose SMCJ16A when system-level surge tests (e.g., IEC 61000-4-5) demand >1 kV/2 Ω coupling; not drop-in compatible with SMB footprint. |
Compared with SMAJ16A and SMCJ16A, the TPSMB16AHE3_A/H uniquely balances 600 W surge capacity, AEC-Q101 compliance, and SMB footprint - making it optimal for space-constrained automotive modules requiring validated reliability without board redesign.

FAQ
What is the maximum clamping voltage of the TPSMB16AHE3_A/H under standard test conditions?
The TPSMB16AHE3_A/H has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 26.7 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical overvoltage thresholds during surge events. The TPSMB16AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPSMB16AHE3_A/H qualified for automotive applications?
Yes, the TPSMB16AHE3_A/H is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS compliance and automotive-grade reliability. It undergoes rigorous stress testing including high-temperature reverse bias, temperature cycling, and ESD per the AEC-Q101 standard. The TPSMB16AHE3_A/H is explicitly intended for use in automotive power distribution, body control modules, and ADAS sensor interfaces.
What does the "HE3" suffix mean in TPSMB16AHE3_A/H?
The "HE3" suffix in TPSMB16AHE3_A/H denotes a RoHS-compliant, AEC-Q101 qualified version with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements. The "_A/H" indicates packaging in 7" diameter plastic tape and reel with 750 units per reel. The TPSMB16AHE3_A/H is distinct from HM3 variants, which add halogen-free molding compound.
Can the TPSMB16AHE3_A/H be used in bidirectional configurations?
No, the TPSMB16AHE3_A/H is unidirectional only, as confirmed in the Vishay datasheet. It conducts surge current from cathode to anode when reverse-biased beyond VBR. For bidirectional protection, two TPSMB16AHE3_A/H devices must be connected in series opposing configuration, or a dedicated bidirectional TVS such as the TPSMB16CA should be selected instead of the TPSMB16AHE3_A/H.
What is the thermal derating behavior of the TPSMB16AHE3_A/H above 25 °C ambient?
The TPSMB16AHE3_A/H follows the derating curve in Figure 2 of its datasheet: peak pulse power decreases linearly from 600 W at 25 °C to approximately 300 W at 125 °C ambient. This derating applies to both single-pulse and repetitive 0.01% duty cycle operation. The TPSMB16AHE3_A/H retains full functionality up to +185 °C junction temperature, but sustained high-power surges require thermal management per the 5.0 mm × 5.0 mm pad layout specification.
