Product details
Overview
TPSMC47A802HE3_A/H 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 minimum 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 ECUs, industrial motor drives, and telecom power rails.
For engineers reviewing the TPSMC47A802HE3_A/H datasheet, TPSMC47A802HE3_A/H pinout, TPSMC47A802HE3_A/H application, or TPSMC47A802HE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, and compliance with IEC 61000-4-5 surge immunity requirements.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress. Its 185 °C maximum junction temperature enables operation in under-hood automotive environments and high-temperature industrial enclosures without derating penalties.
The device meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing (HE3 suffix), with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Clamping performance is validated using 10/1000 μs waveform per ANSI/IEEE C62.35.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 44.7 V - ensures reliable conduction onset above normal 40.2 V system operating voltage |
| VWM | 40.2 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| PPPM | 1500 W - handles 10/1000 μs surges up to 23.1 A without failure (tested on 8.0 mm × 8.0 mm copper pads) |
| VC @ IPPM | 64.8 V - limits protected circuit voltage during worst-case surge, staying below typical 65–75 V IC absolute max ratings |
| TJ max | +185 °C - supports AEC-Q101 automotive qualification and extended thermal margin in sealed enclosures |
| Polarity | Unidirectional - protects against positive-going transients only; cathode band denotes terminal polarity |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 7.11 mm × 6.60 mm body and 3.20 mm lead width |
Pinout & Package
TPSMC47A802HE3_A/H uses the DO-214AB (SMC) package: molded epoxy case meeting UL 94 V-0, matte tin-plated leads, cathode indicated by a color band. Mounting requires 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal for full 1500 W rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry point during forward conduction | Connected to protected line (e.g., 42 V battery rail); must be routed with low-inductance path to ground |
| Cathode | Surge current exit point to ground reference | Connected directly to chassis or power ground plane; color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |
| Junction passivation | Reduces leakage drift over time and improves long-term stability at 150 °C operating temperature |
| MSL Level 1 | Allows unlimited floor life and reflow at 260 °C peak without preconditioning |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 5a) |
| 10/1000 μs waveform compliance | Meets IEC 61000-4-5 Level 4 (4 kV) surge test requirements when properly mounted |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus Clamp |
|---|---|
|
Use Scenario: Suppresses load dump transients (up to 120 V, 400 ms) on 42 V mild-hybrid vehicle battery feeds. IC Role / Device Role / Timing Role: Unidirectional TVS clamps positive overvoltage spikes before they reach downstream DC/DC controllers and gate drivers. Use Value: Maintains VC ≤ 64.8 V during 1500 W surges, protecting 65 V-rated MOSFETs and PMICs without crowbar action. |
Use Scenario: Absorbs inductive kickback from 24 V solenoid valves and BLDC motor phase switching in factory automation PLCs. IC Role / Device Role / Timing Role: Fast-response (sub-nanosecond) clamping element placed across DC bus terminals to limit voltage overshoot during turn-off. Use Value: Limits transient voltage to <65 V within 100 ns, preventing gate oxide rupture in 75 V rated half-bridge drivers. |
| Telecom Power Supply Input Stage | Consumer Appliance Main Board Surge Guard |
|
Use Scenario: Guards AC/DC adapter output against lightning-induced surges entering via PoE or external DC input in base station power modules. IC Role / Device Role / Timing Role: Primary overvoltage clamp on +48 V telecom distribution rail upstream of point-of-load regulators. Use Value: Withstands 20× 1500 W surges per minute (per spec note 3), ensuring field reliability in outdoor cabinet deployments. |
Use Scenario: Protects microcontroller I/O and relay driver circuits in washing machine control boards exposed to ESD and relay coil transients. IC Role / Device Role / Timing Role: Secondary-level TVS on 5 V/12 V internal rails, triggered after primary MOV suppression. Use Value: Delivers sub-100 ns response and <1 μA leakage at 40.2 V, eliminating false resets while preserving standby power budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ45A-E3/57T | Lower PPPM (400 W), smaller SMA package (DO-214AC), VC = 72.7 V at 12.5 A | Rated for consumer-grade ambient (TJ max = 150 °C), not AEC-Q101 qualified | Select for cost-sensitive non-automotive designs where 400 W surge margin suffices and board space is constrained. |
| 1.5KE47A | Through-hole DO-201 package, higher VC = 70.1 V at 21.5 A, same 1500 W rating but larger footprint | Lacks MSL Level 1 and JESD201 whisker compliance; unsuitable for automated SMT assembly | Choose only for legacy through-hole designs requiring identical electrical specs but no surface-mount compatibility. |
Compared with SMAJ45A-E3/57T and 1.5KE47A, TPSMC47A802HE3_A/H delivers automotive-grade reliability (AEC-Q101, 185 °C), SMT-ready DO-214AB packaging, and lower clamping voltage - making it optimal for new automotive, industrial, and telecom designs requiring high surge immunity and long-term stability.

FAQ
What is the exact breakdown voltage range for TPSMC47A802HE3_A/H?
The TPSMC47A802HE3_A/H has a minimum breakdown voltage (VBR) of 44.7 V and a maximum of 49.4 V at 1 mA test current, per Vishay Document 88407. This 4.7 V tolerance window ensures consistent triggering across production lots while maintaining safe margin above its 40.2 V standoff voltage.
Is TPSMC47A802HE3_A/H suitable for bidirectional surge protection?
No - TPSMC47A802HE3_A/H is unidirectional only, with cathode marked by a color band. It clamps positive transients relative to ground. For bidirectional protection (e.g., data lines), a separate symmetric TVS like SMBJ45CA or dedicated dual-rail design is required.
Does TPSMC47A802HE3_A/H meet RoHS and REACH requirements?
Yes - the HE3 suffix confirms TPSMC47A802HE3_A/H is RoHS-compliant per EU Directive 2011/65/EU and satisfies Vishay's material categorization standard (Document 99912). Lead content is below 1000 ppm, and all restricted substances are within specified thresholds.
What is the maximum allowable PCB pad size for full 1500 W rating of TPSMC47A802HE3_A/H?
To achieve the full 1500 W peak pulse power rating, TPSMC47A802HE3_A/H must be mounted on 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads at each terminal, as defined in Vishay Document 88407, Note (2). Smaller pads reduce thermal dissipation and require derating per Figure 2.
Can TPSMC47A802HE3_A/H replace older TPSMC47A variants with different suffixes?
Yes - TPSMC47A802HE3_A/H retains identical electrical specs and DO-214AB mechanical form factor as other TPSMC47A variants. The "802" denotes tape-and-reel packaging (850 pcs per 7″ reel), and "HE3_A/H" confirms RoHS/AEC-Q101 compliance; no circuit redesign is needed.
