Product details
Overview
TPSMC10AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500 W peak pulse power (10/1000 μs), 14.5 V clamping voltage at 103 A surge current, and 9.5–10.5 V breakdown voltage at 1 mA test current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients.
For engineers reviewing the TPSMC10AHE3_A/H datasheet, TPSMC10AHE3_A/H pinout, TPSMC10AHE3_A/H application, or TPSMC10AHE3_A/H equivalent, key selection criteria include unidirectional polarity, 185 °C junction temperature rating, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.45), and compatibility with high-reliability PCB assembly per J-STD-002 and JESD 22-B102.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve stable clamping under repetitive surge stress. Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow soldering up to 260 °C and long-term operation in under-hood automotive environments.
The device operates exclusively in unidirectional mode with cathode band marking, and its 10/1000 μs waveform response delivers sub-nanosecond turn-on for effective suppression of ESD and load-dump transients. Clamping performance is validated at 103 A IPPM with VC = 14.5 V, ensuring robust protection margin over 12 V system rails.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower PPPM (400 W), same DO-214AC (SMA) package, VBR = 11.1–12.3 V, VC = 16.7 V at 24.7 A | Not suitable for automotive load-dump; limited to consumer-grade surge immunity (IEC 61000-4-5 Level 2) | Select when cost sensitivity outweighs energy handling; verify layout clearance for lower surge current density |
| 1.5KE10A | Through-hole TO-218 package, higher PPPM (1500 W), VBR = 8.55–9.45 V, VC = 14.5 V at 103 A, but no AEC-Q101 qualification | Lacks automotive qualification and MSL Level 1; unsuitable for SMT production or under-hood use | Choose only for legacy through-hole designs where rework tolerance and manual assembly are acceptable |
Compared with SMAJ10A and 1.5KE10A, TPSMC10AHE3_A/H uniquely combines AEC-Q101 qualification, 185 °C junction rating, and SMC package thermal performance-enabling direct integration into high-density automotive PCBs without derating or secondary protection stages.

FAQ
What is the clamping voltage of the TPSMC10AHE3_A/H at its rated peak pulse current?
The TPSMC10AHE3_A/H has a maximum clamping voltage (VC) of 14.5 V at 103 A peak pulse current (IPPM), measured using a 10/1000 μs waveform. This value ensures that protected circuits remain within safe operating limits during high-energy transients. The clamping ratio (VC/VBR) is approximately 1.45, confirming tight voltage control. This specification is verified per ANSI/IEEE C62.35 and is critical for safeguarding 16 V-rated components downstream of the TPSMC10AHE3_A/H.
Is the TPSMC10AHE3_A/H suitable for automotive applications?
Yes, the TPSMC10AHE3_A/H is AEC-Q101 qualified and rated for operation up to 185 °C junction temperature, making it suitable for under-hood automotive applications such as engine control units and body control modules. Its DO-214AB (SMC) package meets MSL Level 1 and supports lead-free reflow up to 260 °C. The TPSMC10AHE3_A/H is explicitly listed in Vishay's AEC-Q101 qualified product matrix and validated for load-dump and ESD immunity per ISO 7637-2 and ISO 10605.
What does the "HE3_A/H" suffix indicate in TPSMC10AHE3_A/H?
The "HE3" suffix denotes Vishay's RoHS-compliant, AEC-Q101 qualified construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards; "A" indicates ±5 % tolerance on VBR; "H" specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This full suffix confirms compliance with automotive supply chain requirements including whisker resistance (JESD 201 Class 2) and material declaration (Vishay Doc. #99912).
How does the TPSMC10AHE3_A/H compare to bidirectional TVS diodes?
The TPSMC10AHE3_A/H is unidirectional only, meaning it conducts transient current in one direction-from cathode to anode-making it ideal for DC power rail and signal line protection where polarity is fixed. Unlike bidirectional variants, it offers lower leakage at VWM (20 μA max at 8.55 V) and tighter VBR tolerance. Bidirectional equivalents would require higher stand-off voltage ratings to avoid false triggering, increasing clamping voltage and reducing protection margin-so the TPSMC10AHE3_A/H is preferred for 12 V automotive and industrial DC systems.
What is the maximum reverse leakage current of the TPSMC10AHE3_A/H at operating temperature?
The TPSMC10AHE3_A/H exhibits a maximum reverse leakage current (IR) of 20 μA at its stand-off voltage (VWM = 8.55 V) and 25 °C ambient. At elevated junction temperature (TJ = 150 °C), leakage rises to 200 μA-still well within safe limits for most 12 V systems. This controlled leakage ensures minimal power loss in always-on circuits and avoids false triggering of downstream monitoring circuitry. All values are measured per ANSI/IEEE C62.35 and confirmed in Vishay Document #88407.
