Product details
Overview
TPSMC39A001HE3_A/I 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), 37.1–41.0 V breakdown voltage, and 53.9 V clamping voltage at 27.8 A peak surge current. It delivers high-temperature operation up to +185 °C and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the TPSMC39A001HE3_A/I datasheet, TPSMC39A001HE3_A/I pinout, TPSMC39A001HE3_A/I application, or TPSMC39A001HE3_A/I equivalent, key selection criteria include unidirectional polarity, 33.3 V stand-off voltage, low incremental surge resistance, fast response time, and compliance with J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker testing.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for junction stability under repetitive surge stress. Its 185 °C maximum junction temperature and AEC-Q101 qualification support deployment in under-hood automotive modules and industrial motor drives where thermal derating and reliability are critical.
The device operates exclusively in unidirectional mode with a color-band cathode marking, and achieves clamping within nanoseconds of transient onset. Its 1500 W peak pulse power rating is validated on 8.0 mm × 8.0 mm copper pads per terminal, per JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 37.1 V min. to 41.0 V max. at 1 mA - defines precise voltage threshold for avalanche conduction during overvoltage events |
| Stand-off Voltage (VWM) | 33.3 V - maximum continuous reverse working voltage before leakage exceeds 1 μA, ensuring no false triggering in normal operation |
| Clamping Voltage (VC) | 53.9 V at 27.8 A IPPM - limits downstream IC voltage during 10/1000 μs transients, protecting 3.3 V/5 V/12 V logic and power rails |
| Peak Pulse Power (PPPM) | 1500 W (10/1000 μs waveform) - sustains high-energy surges from inductive switching or ESD without failure |
| Operating Temperature (TJ) | -65 °C to +185 °C - enables use in extreme environments including engine control units and industrial inverters |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability per stress test requirements including HTGB, HTRB, and temperature cycling |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, RoHS-compliant, UL 94 V-0 molding compound. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to system ground or low-side reference | Provides low-impedance path to ground during reverse-transient clamping; must be routed with minimal inductance |
| Cathode | Current exit point in forward bias; connected to protected line (e.g., CAN_H, LIN, 12 V rail) | Marked by color band; carries full surge current during clamping; requires direct connection to protected node |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Reduces leakage drift and improves long-term stability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay coil decay or load dump without degradation |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free SMT assembly without preconditioning or special handling |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under mechanical stress and temperature gradients, critical for automotive longevity |
| Uni-directional polarity only | Simplifies layout and eliminates ambiguity in cathode orientation; avoids misapplication in DC-biased lines |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | Lower PPPM = 400 W; VBR = 40–44.4 V; DO-214AC (SMA) package; 150 °C TJ max | Not AEC-Q101 qualified; unsuitable for automotive under-hood use; limited to consumer/industrial board-level protection | Select when cost sensitivity outweighs surge energy requirement and automotive qualification is unnecessary |
| SMCJ36A | Same PPPM = 1500 W; VBR = 40–44.4 V; DO-214AB (SMC) package; AEC-Q101 qualified; TJ = 175 °C | Marginally lower max junction temperature (175 °C vs. 185 °C); identical footprint and polarity | Acceptable drop-in alternative where 10 °C thermal margin reduction is acceptable in thermal-limited designs |

FAQ
What is the exact breakdown voltage range for TPSMC39A001HE3_A/I?
The TPSMC39A001HE3_A/I has a guaranteed breakdown voltage (VBR) range of 37.1 V minimum to 41.0 V maximum at 1 mA test current, as specified in the Vishay datasheet document 88407, page 2. This ±5 % tolerance is confirmed by the 'A' suffix in the part number and applies under standard test conditions at TA = 25 °C. The TPSMC39A001HE3_A/I maintains this specification across its full operating temperature range.
Is TPSMC39A001HE3_A/I suitable for automotive under-hood applications?
Yes, the TPSMC39A001HE3_A/I is AEC-Q101 qualified and rated for continuous operation from -65 °C to +185 °C junction temperature, making it fully suitable for under-hood automotive applications such as engine control modules, transmission control units, and body control modules. Its DO-214AB package and HE3 suffix also meet JESD 201 Class 2 whisker resistance requirements critical for long-term reliability in vibration-prone environments.
What does the 'HE3_A/I' suffix mean in TPSMC39A001HE3_A/I?
The 'HE3' denotes Vishay's RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads and JESD 201 Class 2 whisker resistance. 'A' indicates ±5 % tolerance on VBR, and 'I' specifies packaging in 13-inch diameter plastic tape and reel with 3500 units per reel. The full designation TPSMC39A001HE3_A/I uniquely identifies this specific configuration of the TPSMC39A001HE3_A/I device.
Does TPSMC39A001HE3_A/I have bidirectional capability?
No, the TPSMC39A001HE3_A/I is strictly unidirectional, as explicitly stated in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It is designed for DC-biased lines where reverse conduction is not required. For bidirectional protection, engineers must select a different family such as the SMBJ or SMCJ series with 'CA' suffix (e.g., SMCJ33CA), not the TPSMC39A001HE3_A/I.
What is the maximum clamping voltage of TPSMC39A001HE3_A/I at rated surge current?
The TPSMC39A001HE3_A/I has a maximum clamping voltage (VC) of 53.9 V at 27.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform, per datasheet page 2. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal and represents the upper limit of voltage seen by downstream circuitry during worst-case transient events.
