Product details
Overview
TPSMC47A802HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for high-energy surge protection on power and signal lines. It features 44.7 V to 49.4 V breakdown voltage (VBR), 40.2 V maximum standoff voltage (VWM), 1500 W peak pulse power (10/1000 µs), 23.1 A peak pulse current (IPPM), and 64.8 V clamping voltage (VC) - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the TPSMC47A802HE3_A/I datasheet, TPSMC47A802HE3_A/I pinout, TPSMC47A802HE3_A/I application, or TPSMC47A802HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, DO-214AB mechanical compatibility, and clamping performance under 10/1000 µs transients.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its junction design enables reliable operation up to TJ = 185 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
The device delivers precise clamping at 64.8 V under 23.1 A IPPM, with <1 ns response time and <3.5 V forward voltage at 100 A. It is rated for non-repetitive 8.3 ms half-sine surges up to 200 A (IFSM) and exhibits ≤1 µA reverse leakage at VWM = 40.2 V (TA = 25 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V - defines minimum voltage at which avalanche conduction begins reliably; ensures protection activation above normal 40.2 V operating rail. |
| VWM | 40.2 V - maximum continuous reverse working voltage; sets upper limit for safe DC or AC peak operation without leakage degradation. |
| VC @ IPPM | 64.8 V - clamped voltage during 23.1 A 10/1000 µs surge; determines protected circuit's maximum transient overvoltage exposure. |
| PPPM | 1500 W - peak pulse power handling capability; supports robust immunity against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges. |
| TJ max. | +185 °C - extended junction temperature rating; enables use in under-hood automotive and high-ambient industrial environments. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per stress test plan. |
| Package | DO-214AB (SMC) - standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement; compatible with automated SMT assembly. |
Pinout & Package
DO-214AB (SMC) package with cathode-indicating band; two-terminal device with anode and cathode leads. Matte tin-plated terminals meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential side of protected line; enables fast turn-on during positive transients relative to cathode. |
| Cathode | Current exit point during reverse-biased clamping | Connected to higher-potential rail (e.g., VBAT); conducts surge current to ground when VAK exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables single-device protection against severe load dump and inductive switching events per ISO 16750-2. |
| AEC-Q101 qualification | Validates long-term reliability under automotive thermal cycling, humidity, and vibration stress conditions. |
| 185 °C maximum junction temperature | Supports placement near heat sources (e.g., power converters) without derating in engine control units. |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes overvoltage stress on downstream MOSFETs or ICs while maintaining margin above VWM. |
| MSL Level 1 (260 °C peak) | Allows standard lead-free reflow without preconditioning or special handling in high-volume manufacturing. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ48A-E3/5A (Vishay) | DO-214AC (SMA) package; 48 V VBR; 77.4 V VC @ 13.7 A; 400 W PPPM | Lower power rating and smaller footprint; suitable only for sub-1 kV/m surge immunity levels. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 Level 3. |
| 1.5KE47A (ON Semiconductor) | DO-201AD (Axial) through-hole package; same 47 V nominal VBR; 69.4 V VC @ 21.7 A; 1500 W rating | Requires manual or wave soldering; incompatible with high-speed SMT lines and automotive automated assembly. | Choose only for legacy through-hole designs where rework flexibility outweighs production efficiency needs. |
