Overview
TPSMC10AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 10 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 14.5 V maximum clamping voltage at 103 A surge current, and operates up to +185 °C junction temperature - ideal for automotive power rail protection.
For engineers reviewing the TPSMC10AHE3_B/I datasheet, TPSMC10AHE3_B/I pinout, TPSMC10AHE3_B/I application, or TPSMC10AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 10/1000 µs waveform capability, and compatibility with high-reliability automotive PCB layouts requiring RoHS-compliant, matte tin-plated leads.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress. Its 185 °C maximum junction temperature and low incremental surge resistance support operation in engine bay and powertrain control modules where thermal derating is critical.
The device responds in sub-nanosecond time to transients induced by inductive load switching, with clamping performance validated per ANSI/IEEE C62.35. It is rated for non-repetitive 10/1000 µs pulses up to 1500 W when mounted on 8.0 mm × 8.0 mm copper pads - matching standard automotive PCB thermal pad practices.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), same VBR range, SMA package (smaller thermal mass) | Not AEC-Q101 qualified; limited to consumer/industrial use below 150 °C ambient | Select when cost and board space are prioritized over automotive reliability and high-energy surge handling |
| TPSMC10AHM3_B/I | Identical electrical specs; HM3 suffix denotes halogen-free construction (vs. HE3's RoHS-only) | Required for OEMs enforcing halogen-free material declarations (e.g., VW TL 81315, GMW 3172) | Choose HM3 version if chemical compliance mandates exceed standard RoHS requirements |
Compared with SMAJ10A and TPSMC10AHM3_B/I, the TPSMC10AHE3_B/I provides the optimal balance of automotive qualification, 1500 W surge capacity, and SMC package thermal robustness - making it the preferred choice for safety-critical 12 V power rail protection where both reliability and energy handling are non-negotiable.

FAQ
What is the clamping voltage of TPSMC10AHE3_B/I at its rated peak pulse current?
The TPSMC10AHE3_B/I has a maximum clamping voltage (VC) of 14.5 V when subjected to its peak pulse current (IPPM) of 103 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with specified PCB mounting conditions (0.31" × 0.31" copper pads). The clamping performance remains stable across its full operating temperature range due to low temperature coefficient (0.064 %/°C).
Is TPSMC10AHE3_B/I qualified for automotive applications?
Yes, TPSMC10AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified variants. It meets automotive reliability requirements including high-temperature operation up to +185 °C junction temperature, humidity testing, and mechanical shock/vibration standards required for powertrain and body electronics.
What does the "HE3" and "B/I" suffix mean in TPSMC10AHE3_B/I?
In TPSMC10AHE3_B/I, "HE3" indicates RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads; "B" is the revision code; and "I" specifies packaging in 13" diameter plastic tape and reel with a base quantity of 3500 units. This differs from "H"-coded reels (7", 850 units) and "HM3" variants (halogen-free + RoHS + AEC-Q101).
Can TPSMC10AHE3_B/I be used in bidirectional transient protection circuits?
No, TPSMC10AHE3_B/I is unidirectional only, as explicitly stated in the Vishay datasheet. It protects against positive-going transients on the cathode side relative to anode. For bidirectional protection, two devices in series opposition or a dedicated bidirectional TVS (e.g., TPSMC10CA) must be used - the TPSMC10AHE3_B/I alone cannot clamp negative excursions.
What is the maximum leakage current of TPSMC10AHE3_B/I at its stand-off voltage?
At its stand-off voltage (VWM) of 8.55 V and TA = 25 °C, the TPSMC10AHE3_B/I exhibits a maximum reverse leakage current (IR) of 20 µA. At elevated temperature (TJ = 150 °C), leakage increases to 200 µA - a design consideration for low-power always-on circuits where cumulative leakage across multiple TVS devices could affect quiescent current budgets.
