Product details
Overview
P6SMB8.2AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for circuit protection against ESD and surge transients. It features 7.79 V minimum breakdown voltage (VBR), 7.02 V standoff voltage (VWM), 12.1 V maximum clamping voltage (VC) at 49.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines of automotive sensor interfaces.
For engineers reviewing the P6SMB8.2AHE3_A/H datasheet, P6SMB8.2AHE3_A/H pinout, P6SMB8.2AHE3_A/H application, or P6SMB8.2AHE3_A/H equivalent, key selection criteria include clamping performance under 50 A surge, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated junction technology for stable avalanche behavior. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of inductive switching spikes and lightning-induced transients on DC power inputs and analog sensor lines.
The device is rated for repetitive 0.01% duty cycle surges and derates linearly above 25 °C ambient per Fig. 2; it meets J-STD-020 MSL Level 1 (260 °C peak reflow) and supports soldering per J-STD-002 and JESD 22-B102 standards. The AEC-Q101 qualification confirms suitability for automotive electronics environments.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial Power Rail Clamping |
|---|---|
Use Scenario: Protecting LIN bus transceivers and analog output sensors (e.g., pressure, temperature) in engine control modules from load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor VCC and chassis ground, clamping transients within 1 ns to prevent latch-up or gate oxide damage. Use Value: Limits voltage excursion to ≤12.1 V during 49.6 A surge, preserving sensor accuracy and MCU reset integrity in ASIL-B systems. | Use Scenario: Safeguarding 5 V/12 V DC-DC converter outputs in PLC I/O modules exposed to relay coil switching noise and field wiring surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on secondary-side output rail, absorbing repetitive 600 W pulses without thermal runaway due to RθJA = 100 °C/W. Use Value: Maintains <200 µA leakage at 7.02 V, preventing unnecessary quiescent current draw while enabling compliance with IEC 61000-4-4 level 3. |
| Consumer USB Port ESD Protection | Telecom Line Interface Surge Suppression |
Use Scenario: Secondary-level ESD protection on USB VBUS lines in set-top boxes and smart displays where primary protection resides upstream. IC Role / Device Role / Timing Role: Fast-clamping unidirectional suppressor placed after fuse and upstream of USB controller, triggered only during >7.79 V events. Use Value: Achieves <12.1 V clamping at 49.6 A, limiting stress on USB PHY transceivers and meeting IEC 61000-4-2 ±15 kV contact discharge requirements. | Use Scenario: Back-to-back TVS configuration (with bidirectional variant) on RS-485 data lines in base station remote units subjected to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Paired unidirectional devices (anode-to-anode or cathode-to-cathode) providing symmetric clamping on differential pairs. Use Value: Delivers matched VBR (7.79–8.61 V) and VC (12.1 V) for balanced transient suppression, minimizing signal distortion on 10 Mbps links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Lower PPPM (400 W), higher VC (12.5 V at 38.9 A), same SMB package and AEC-Q101 qualification. | Marginally lower surge handling; suitable for cost-sensitive non-automotive designs with reduced surge threat profile. | Select SMAJ8.0A only if system-level surge testing requires ≤400 W capability and VC margin allows 12.5 V. |
| 1.5SMC8.2A | Higher package thermal mass (SMC), 600 W rating, but RθJA = 15 °C/W on large pads - not AEC-Q101 qualified. | Requires larger PCB area; lacks automotive qualification; better for industrial mains-connected equipment with heatsinking. | Choose 1.5SMC8.2A when board space permits larger SMC footprint and AEC-Q101 is not mandated. |
Compared with SMAJ8.0A and 1.5SMC8.2A, P6SMB8.2AHE3_A/H uniquely combines AEC-Q101 qualification, 600 W surge capacity, and SMB footprint - making it optimal for space-constrained automotive ECUs requiring validated reliability and precise clamping at 12.1 V.

FAQ
What is the clamping voltage of P6SMB8.2AHE3_A/H at its rated peak pulse current?
The P6SMB8.2AHE3_A/H has a maximum clamping voltage (VC) of 12.1 V at its rated peak pulse current (IPPM) of 49.6 A, measured using the standardized 10/1000 µs double-exponential surge waveform. This value ensures downstream components such as microcontrollers or interface ICs are exposed to no more than 12.1 V during worst-case transient events, directly supporting IEC 61000-4-5 compliance testing.
Is P6SMB8.2AHE3_A/H qualified for automotive applications?
Yes, P6SMB8.2AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation revision 09-Jan-2024 (Document Number: 88370). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock - validating its use in engine control units, body electronics, and ADAS sensor modules.
What is the standoff voltage (VWM) of P6SMB8.2AHE3_A/H and why does it matter?
The standoff voltage (VWM) of P6SMB8.2AHE3_A/H is 7.02 V, representing the maximum continuous reverse voltage the device can block without exceeding 200 µA leakage current. This parameter is critical for ensuring reliable operation on 5 V or 6 V supply rails - it provides sufficient margin above nominal voltage while avoiding false triggering during normal operation or ripple conditions.
Does P6SMB8.2AHE3_A/H have a defined thermal resistance, and how is it measured?
Yes, P6SMB8.2AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per JEDEC standards. This value guides thermal design for continuous power dissipation up to 5.0 W and informs derating curves above 25 °C ambient temperature.
How does the glass passivation in P6SMB8.2AHE3_A/H improve long-term reliability?
The glass passivated chip junction in P6SMB8.2AHE3_A/H enhances long-term reliability by stabilizing the avalanche breakdown characteristics, reducing parameter drift over time and temperature, and minimizing leakage current (<200 µA at VWM). This construction also improves resistance to humidity ingress and metallization corrosion - essential for automotive and industrial deployments exceeding 15-year service life.
