Product details
Overview
TPSMC8.2AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping inductive switching surges and lightning-induced transients on power and signal lines. It features 8.2 V nominal breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 124 V maximum clamping voltage at 124 A peak pulse current, and operates up to +185 °C junction temperature - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMC8.2AHE3_B/H datasheet, TPSMC8.2AHE3_B/H pinout, TPSMC8.2AHE3_B/H application, or TPSMC8.2AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 124 V clamping performance at rated IPPM, thermal derating above 25 °C, and compatibility with reflow profiles meeting J-STD-020 MSL level 1 (260 °C peak).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and fast-rising transients. Its 185 °C maximum junction temperature rating supports operation in under-hood automotive environments and high-temperature industrial enclosures without thermal derating penalties beyond those defined in Fig. 2.
The device is optimized for 10/1000 µs waveform compliance per ANSI/IEEE C62.35, with clamping voltage tightly specified at 124 V under 124 A peak pulse current. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (≤200 µA at VWM) at 25 °C and ≤2000 µA at 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.79 / 8.20 / 8.61 V at 10 mA - defines precise voltage threshold where avalanche conduction begins, critical for matching system overvoltage tolerance margins. |
| VWM | 7.02 V - maximum continuous reverse operating voltage before significant leakage; ensures no false triggering in nominal 5 V–6 V rail applications. |
| IPPM | 124 A (10/1000 µs) - peak surge current capability directly determines energy handling (1500 W) and clamping robustness under standardized transient stress. |
| VC @ IPPM | 124 V - clamped voltage seen by protected IC/MOSFET during full-rated surge; sets absolute upper bound on downstream component stress. |
| TJ max. | +185 °C - enables use in AEC-Q101-compliant automotive modules (e.g., body control units) without external heatsinking or derating below ambient 125 °C. |
| Polarity | Unidirectional - provides forward conduction path for negative-going transients on positive rails; requires correct cathode orientation toward protected circuit side. |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement for thermal dissipation and 1500 W pulse handling. |
Pinout & Package
TPSMC8.2AHE3_B/H is housed in the SMC (DO-214AB) package: molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, MSL level 1 compliant, and cathode indicated by a color band. Dimensions: 6.22 mm × 5.59 mm × 2.62 mm (L × W × H), with 0.126" (3.20 mm) minimum cathode/anode pad spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference plane; must sustain 200 A non-repetitive forward surge (IFSM) without bond wire failure. |
| Cathode | Protected line connection point | Connected to line being safeguarded (e.g., 5 V supply rail); reverse-biased during normal operation, avalanches when VIN exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS sensor, and infotainment power rail protection. |
| 1500 W peak pulse power (10/1000 µs) | Enables single-device protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges without parallel staging. |
| Low clamping ratio (VC/VBR ≈ 15.1) | Minimizes overvoltage overshoot during clamping - critical for safeguarding 12 V-tolerant microcontrollers and CAN transceivers. |
| TJ = 185 °C capability | Eliminates need for thermal derating in sealed enclosures up to +125 °C ambient, supporting under-dash and powertrain module deployment. |
| MSL level 1 (260 °C peak) | Permits standard lead-free reflow without moisture sensitivity concerns - reduces manufacturing risk and eliminates bake requirements pre-assembly. |
Applications
| Automotive Sensor Protection | Industrial Power Supply Input |

Use Value: With 7.02 V VWM, it remains inactive during 5 V nominal operation but clamps to 124 V during 100 V load dump events - preserving sensor functionality and avoiding latch-up. |
Use Scenario: Safeguarding AC-DC converter primary-side MOSFETs and controller ICs against switching-induced voltage spikes in factory automation PSUs. IC Role / Device Role / Timing Role: Mounted across bulk capacitor terminals to absorb reflected energy from transformer leakage inductance during MOSFET turn-off. Use Value: 1500 W rating handles repetitive 10/1000 µs surges up to 4 pulses/minute; 124 V clamping prevents MOSFET VDSS overstress during 400 V DC link operation. |
| Telecom Line Interface | Consumer USB Power Delivery |
|
Use Scenario: Shielding Ethernet PHY front-end components (magnetics, magneto-couplers) from induced surges on outdoor cabling in PoE-powered access points. IC Role / Device Role / Timing Role: Installed on secondary side of isolation transformer to limit common-mode transients reaching PHY silicon. Use Value: 185 °C TJ max allows uninterrupted operation inside sealed outdoor enclosures; 124 V clamping protects 3.3 V PHY I/O pins via series impedance limiting. |
Use Scenario: Preventing damage to USB-C port controllers and PD sink ICs during hot-plug events and cable ESD discharge in portable chargers. IC Role / Device Role / Timing Role: Placed between VBUS and GND to shunt ESD strikes (IEC 61000-4-2 ±15 kV contact) before reaching the PD controller's internal LDO and communication logic. Use Value: Sub-1 ns response time ensures clamping initiates before internal gate oxide breakdown; 200 µA leakage at 7.02 V avoids battery drain in standby mode. |
