Product details
Overview
P6SMB220AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), designed to protect power rails and signal lines in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB220AHE3_A/H datasheet, P6SMB220AHE3_A/H pinout, P6SMB220AHE3_A/H application, or P6SMB220AHE3_A/H equivalent, this AEC-Q101 qualified device offers verified surge immunity per IEC 61000-4-2/4-5, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly and high-reliability under-hood applications.
Technical Context
The P6SMB220AHE3_A/H operates as a unidirectional avalanche clamp, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its 600 W peak pulse power rating (10/1000 μs waveform) is sustained with 0.01% duty cycle, and it maintains stable clamping performance across -65 °C to +150 °C junction temperature range.
Designed for placement on 0.2" × 0.2" copper pads per terminal, the device exhibits RθJA = 100 °C/W and supports repetitive surge events when thermally managed. Polarity is marked by cathode band; no marking applies to bidirectional variants - but P6SMB220AHE3_A/H is explicitly unidirectional per part numbering and electrical table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 185 V - Maximum continuous reverse operating voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 209–231 V at 1 mA - Verified avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 328 V at IPPM = 1.8 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs transient; determines downstream component stress. |
| PPPM | 600 W - Surge energy handling capacity per single 10/1000 μs pulse; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID (Leakage) | 1 μA max at VWM - Ultra-low reverse leakage preserves system efficiency and battery life in always-on circuits. |
| TJ max | +150 °C - Enables deployment in under-hood automotive environments and industrial enclosures without derating. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A-E3/5B | Same VWM/VBR/VC specs; SMA package (DO-214AC), higher RθJA (150 °C/W), non-AEC-Q101. | Limited to commercial-grade consumer/industrial use; unsuitable for automotive under-hood deployment. | Select when cost-sensitive, non-automotive designs require identical electrical performance in smaller footprint. |
| 1.5SMC220A | Same 220 V rating; larger SMC (DO-214AB) package, 1.5 kW PPPM, RθJL = 10 °C/W, no AEC-Q101 variant. | Better thermal handling for high-duty-cycle surges; lacks automotive qualification and lead finish compliance. | Choose for high-energy industrial surge zones where PCB space allows larger package and AEC-Q101 is not mandated. |
Compared with SMAJ220A-E3/5B and 1.5SMC220A, the P6SMB220AHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint compatibility with automated placement, and verified 150 °C operation - making it the only drop-in solution for automotive Tier-1 power rail protection where space, reliability, and thermal constraints intersect.

FAQ
What is the clamping voltage of the P6SMB220AHE3_A/H under a 10/1000 µs surge?
The P6SMB220AHE3_A/H has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB220AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is the P6SMB220AHE3_A/H suitable for automotive applications?
Yes, the P6SMB220AHE3_A/H is AEC-Q101 qualified and designated for automotive use via the "HE3" suffix, indicating RoHS-compliant construction and validation across temperature cycling, highly accelerated life testing (HALT), and ESD robustness per JESD47. It is deployed in engine control modules, body electronics, and ADAS subsystems where sustained operation up to +150 °C and immunity to load dump transients are required. The P6SMB220AHE3_A/H meets these requirements without derating.
What does the "_A/H" suffix mean in P6SMB220AHE3_A/H?
The "_A/H" suffix in P6SMB220AHE3_A/H indicates packaging and revision: "A" denotes the standard revision level per Vishay document 88370 (Rev. 09-Jan-2024), and "H" specifies 7-inch plastic tape-and-reel delivery (750 units per reel). The "HE3" portion confirms RoHS-compliant, AEC-Q101 qualified construction with matte tin-plated leads. This full ordering code ensures traceability to validated automotive-grade build standards and assembly-ready packaging.
How does the P6SMB220AHE3_A/H compare to bidirectional TVS diodes?
The P6SMB220AHE3_A/H is unidirectional, meaning it conducts only during reverse-biased overvoltage events - ideal for DC power rail protection where polarity is fixed. Bidirectional variants (e.g., P6SMB220CA) conduct in both directions and suit AC-coupled or floating signal lines. The P6SMB220AHE3_A/H offers lower leakage (1 μA vs. up to 5 μA for some bidirectionals at VWM) and avoids forward conduction during normal operation, preserving efficiency in 24 V/48 V systems.
What is the thermal resistance of the P6SMB220AHE3_A/H?
The P6SMB220AHE3_A/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and a junction-to-ambient resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads. These values enable effective heat dissipation during repetitive surge events and support reliable operation at TJ = +150 °C. The low RθJL is critical for maintaining clamping stability during high-current transients, and the P6SMB220AHE3_A/H is characterized under these exact thermal conditions.
