Product details
Overview
TPSMA8.2AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 8.2 V nominal breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 33.1 V maximum clamping voltage (VC) at 200 A peak pulse current, 400 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - ideal for automotive sensor line protection.
For engineers reviewing the TPSMA8.2AHE3_B/H datasheet, TPSMA8.2AHE3_B/H pinout, TPSMA8.2AHE3_B/H application, or TPSMA8.2AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 200 A IPPM rating, low 50 µA reverse leakage at VWM, and compatibility with high-reliability PCB layouts using 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and fast response to ESD and lightning-induced surges. Its junction design enables stable 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 performance with a typical VBR temperature coefficient of +0.056 %/°C and exhibits low incremental surge resistance, ensuring predictable voltage limiting during repetitive 10/1000 µs transients at 0.01 % duty cycle.

Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus interface ICs and analog sensor outputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between sensor line and ground, activated within <1 ns of overvoltage event. Use Value: Maintains signal integrity below 33.1 V during 200 A transients, preventing latch-up or damage to 5 V tolerant receivers. | Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Standoff protector on input channel, absorbing repetitive 400 W pulses without degradation across 10⁵+ cycles. Use Value: Enables >10-year field life in factory automation due to 185 °C thermal margin and low IR drift over temperature. |
| Consumer Power Adapter Output | Telecom Line Interface |
Use Scenario: Secondary-side overvoltage suppression on USB-C PD or AC/DC adapter 5–20 V outputs exposed to hot-plug and cable ESD. IC Role / Device Role / Timing Role: Fast-clamping shunt device parallel to output capacitor, triggered by >7.02 V excursions. Use Value: Limits output overshoot to ≤33.1 V during 10/1000 µs surges, preserving USB-PD controller and connected devices. | Use Scenario: Protecting Ethernet PHY or RS-485 transceivers on telecom base station backplane traces from lightning-induced common-mode transients. IC Role / Device Role / Timing Role: Unidirectional clamp on VCC-to-ground or signal-to-ground path, coordinated with common-mode chokes. Use Value: Withstands 400 W pulses while maintaining <50 µA leakage at 7.02 V, avoiding false triggering in low-power idle states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Higher VWM (6.89 V), same VBR range (7.78–8.60 V), SMB package (larger footprint) | Lower power density (600 W vs. 400 W), less suitable for space-constrained automotive modules | Select when board layout allows larger SMB pad area and higher clamping margin is acceptable |
| 1.5SMC8.2A | Same VBR (7.79–8.61 V), but DO-214AB package and 1500 W PPPM rating | Designed for higher-energy surges; not AEC-Q101 qualified and lacks MSL Level 1 compliance | Prefer for industrial mains-connected equipment where automotive qualification is unnecessary |
Compared with SMBJ8.0A and 1.5SMC8.2A, the TPSMA8.2AHE3_B/H uniquely combines AEC-Q101 qualification, MSL Level 1 reflow compatibility, and compact SMA footprint - making it optimal for automotive and high-density consumer electronics where reliability and assembly yield are critical.

FAQ
What is the exact breakdown voltage tolerance for TPSMA8.2AHE3_B/H?
The TPSMA8.2AHE3_B/H has a specified breakdown voltage range of 7.79 V (minimum) to 8.61 V (maximum) at 10 mA test current, with 8.20 V nominal. This ±5% tolerance is measured per ANSI/IEEE C62.35 standards and remains stable across temperature due to its +0.056 %/°C VBR coefficient. The TPSMA8.2AHE3_B/H maintains this specification under production lot testing and is guaranteed per Vishay Document Number 88405.
Is TPSMA8.2AHE3_B/H AEC-Q101 qualified and what tests does that include?
Yes, TPSMA8.2AHE3_B/H is AEC-Q101 qualified - confirmed by Vishay's automotive ordering code suffix "HE3", which denotes full qualification per AEC-Q101 Rev D. This includes stress tests such as HTGB (high-temperature gate bias), TC (temperature cycling), AC (autoclave), and mechanical shock. The TPSMA8.2AHE3_B/H qualification applies specifically to the HE3 and HM3 variants, not generic TPSMA8.2A part numbers.
What is the maximum clamping voltage of TPSMA8.2AHE3_B/H and under what test condition?
The maximum clamping voltage of TPSMA8.2AHE3_B/H is 33.1 V, measured at 200 A peak pulse current using a 10/1000 µs waveform per IEC 61000-4-5. This value is guaranteed across the full operating temperature range and reflects worst-case behavior after derating above 25 °C ambient. The TPSMA8.2AHE3_B/H achieves this with low incremental surge resistance, ensuring consistent protection margin for downstream 5 V or 3.3 V ICs.
Does TPSMA8.2AHE3_B/H have a defined moisture sensitivity level and reflow profile?
Yes, TPSMA8.2AHE3_B/H is rated MSL Level 1 per J-STD-020, meaning it has no moisture sensitivity and may be subjected to standard lead-free reflow profiles without pre-baking. Its maximum peak reflow temperature is 260 °C, compatible with IPC/JEDEC J-STD-020D.1 requirements. This MSL Level 1 rating is verified for the HE3 and HM3 variants and documented in Vishay's 88405 datasheet revision 23-Jan-2024.
How does the leakage current of TPSMA8.2AHE3_B/H compare at elevated temperatures?
At 25 °C and VWM = 7.02 V, TPSMA8.2AHE3_B/H exhibits ≤50 µA reverse leakage. At TJ = 150 °C, leakage increases to ≤1000 µA - still within specification and verified per datasheet Table 1. This controlled increase ensures stable operation in under-hood automotive environments. The TPSMA8.2AHE3_B/H maintains functional integrity without thermal runaway, supported by its 185 °C maximum junction rating.
