Product details
Overview
TPSMA16AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping fast voltage transients on power and signal lines. It features a 16.0 V nominal breakdown voltage (VBR), 13.6 V maximum stand-off voltage (VWM), 22.0 V maximum clamping voltage (VC) at 17.8 A peak pulse current, 400 W peak pulse power (10/1000 μs), and operates up to +185 °C junction temperature - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the TPSMA16AHE3_B/I datasheet, TPSMA16AHE3_B/I pinout, TPSMA16AHE3_B/I application, or TPSMA16AHE3_B/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, clamping performance under repetitive surges, and RoHS-compliant packaging details specific to the HE3_B/I variant.
Technical Context
The TPSMA16AHE3_B/I employs passivated anisotropic rectifier technology with optimized junction passivation for stable leakage and clamping across temperature. Its unidirectional architecture provides low incremental surge resistance and sub-nanosecond response time to ESD and lightning-induced transients.
Rated for 400 W peak pulse power (10/1000 μs waveform, 0.01% duty cycle), it supports repetitive surge events when mounted on 5.0 mm × 5.0 mm copper pads and is qualified to AEC-Q101 for automotive use - with TJ max = +185 °C and MSL Level 1 (260 °C reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 V / 16.0 V / 16.8 V - ensures reliable conduction onset above system operating voltage while avoiding false triggering |
| VWM | 13.6 V - maximum continuous reverse voltage before significant leakage; compatible with 12 V automotive rails |
| VC @ IPPM | 22.0 V - clamps transient energy to safe levels for downstream 24 V-rated ICs and MOSFETs |
| IPPM | 17.8 A - peak surge current capability under standardized 10/1000 μs waveform |
| PPPM | 400 W - robust transient energy absorption without thermal runaway under short-duration surges |
| TJ max | +185 °C - enables operation in high-temperature engine bay or industrial control enclosures |
| Leakage @ VWM, TJ = 150 °C | 1.0 μA - ultra-low standby leakage preserves battery life in always-on automotive modules |

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 | Same VBR (16.0 V), but SMB package (DO-214AA); 600 W PPPM; higher thermal mass but larger footprint | Better suited for higher-energy surges where board space allows larger package | Select SMBJ16A only if PCB layout accommodates 4.58 mm × 3.94 mm footprint and requires >400 W rating |
| 1.5SMC16A | Same VBR, but SMC (DO-214AB) package; 1500 W PPPM; higher IPPM (83.3 A); larger size and higher cost | Targeted at heavy-duty industrial equipment requiring MIL-STD-1275 compliance | Choose 1.5SMC16A only when system-level surge tests exceed IEC 61000-4-5 Level 4 (4 kV/2 Ω) |
Compared with SMBJ16A and 1.5SMC16A, the TPSMA16AHE3_B/I delivers optimal balance of AEC-Q101 qualification, compact SMA footprint, and precise 400 W clamping for space-constrained automotive and industrial edge nodes - without over-specifying package size or cost.

FAQ
What is the AEC-Q101 qualification status of the TPSMA16AHE3_B/I?
The TPSMA16AHE3_B/I is AEC-Q101 qualified - confirmed by Vishay's official documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101-qualified variants. This qualification covers temperature cycling, high-temperature operating life, and ESD testing required for automotive under-hood and cabin applications. The TPSMA16AHE3_B/I meets all stress test conditions defined in AEC-Q101 Rev D.
Does the TPSMA16AHE3_B/I support bidirectional transient suppression?
No, the TPSMA16AHE3_B/I is unidirectional only - its electrical characteristics, including VBR, VWM, and clamping behavior, are specified for reverse-biased operation only. Bidirectional protection requires a separate device such as the TPSMA16CA or dual-diode configurations. The datasheet explicitly states "Available in uni-directional polarity only" for the entire TPSMA6.8A–TPSMA43A family.
What is the maximum clamping voltage of the TPSMA16AHE3_B/I at rated peak pulse current?
The TPSMA16AHE3_B/I has a maximum clamping voltage (VC) of 22.0 V at its rated peak pulse current (IPPM) of 17.8 A, measured using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and is critical for ensuring downstream 24 V logic devices remain within absolute maximum ratings during surge events.
How does the TPSMA16AHE3_B/I perform at elevated junction temperatures?
The TPSMA16AHE3_B/I maintains stable clamping performance up to +185 °C junction temperature. Its VBR exhibits a positive temperature coefficient of +0.078 %/°C, meaning breakdown voltage increases linearly with temperature - a key design factor for high-ambient applications like engine control units. Derating curves in Figure 2 confirm usable pulse power down to ~65 % of rated 400 W at +150 °C.
What packaging format does the TPSMA16AHE3_B/I ship in?
The TPSMA16AHE3_B/I ships in 13-inch diameter plastic tape-and-reel format with a base quantity of 7500 units per reel (ordering code suffix "_I"). The tape complies with EIA-481-D standards, and the device is packed per MSL Level 1 requirements - enabling direct placement without baking or dry-pack handling.
