Product details
Overview
P6SMB220AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the 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 MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB220AHE3/5B datasheet, P6SMB220AHE3/5B pinout, P6SMB220AHE3/5B application, or P6SMB220AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HE3 suffix), 600 W peak pulse power rating with 10/1000 μs waveform, and compliance with J-STD-020 MSL level 1 reflow profile up to 260 °C.
Technical Context
This TVS diode operates as a voltage-clamping protection device that remains high-impedance below its 220 V stand-off voltage (VWM), then rapidly transitions to low-impedance conduction above its 209–231 V breakdown range (VBR @ 1 mA), limiting transient voltages to ≤328 V at 1.8 A. Its glass-passivated junction ensures stable avalanche performance and long-term reliability under repetitive surge stress.
The P6SMB220AHE3/5B features a thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling effective heat dissipation on standard 0.2" × 0.2" copper pads. It supports automated SMT placement and meets UL 94 V-0 flammability requirements in its SMB molded package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A-E3/5B | Same VWM/VBR/VC ratings but SMA package (DO-214AC); 10% smaller footprint, higher RθJA (125 °C/W) | Preferred where board space is constrained and thermal pad area is limited | Select SMAJ220A-E3/5B only if layout allows reduced copper area and ambient temperature stays ≤70 °C |
| 1.5SMC220A | Same electrical specs but SMC (DO-214AB) package; 30% larger footprint, lower RθJA (75 °C/W), higher IPPM (2.0 A) | Better suited for high-reliability industrial power supplies with sustained surge duty cycles | Choose 1.5SMC220A when thermal management is critical and PCB real estate permits larger package |
Compared with SMAJ220A-E3/5B, P6SMB220AHE3/5B offers superior thermal performance and AEC-Q101 qualification; versus 1.5SMC220A, it provides identical protection performance in a smaller, automotive-qualified form factor ideal for space-constrained ECUs and sensor nodes.

FAQ
What is the clamping voltage of the P6SMB220AHE3/5B under a 10/1000 μs surge?
The P6SMB220AHE3/5B has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB220AHE3/5B maintains this clamping performance across its specified operating temperature range and after repeated surge exposures.
Is the P6SMB220AHE3/5B qualified for automotive applications?
Yes, the P6SMB220AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB series datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and accelerated life testing. The P6SMB220AHE3/5B is approved for use in automotive power distribution, body electronics, and sensor modules where reliability under thermal and electrical stress is mandatory.
What does the "5B" in P6SMB220AHE3/5B indicate?
The "5B" denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This differs from "52", which indicates a 7-inch reel with 750 units. The "HE3" portion confirms RoHS-compliant construction with AEC-Q101 qualification. The P6SMB220AHE3/5B thus combines automotive-grade reliability with high-volume SMT packaging optimized for automated assembly lines.
How does the P6SMB220AHE3/5B compare to bidirectional TVS diodes like P6SMB220CAHE3/5B?
The P6SMB220AHE3/5B is unidirectional and intended for DC circuits where polarity is fixed-such as battery inputs or regulated power rails-whereas P6SMB220CAHE3/5B is bidirectional and used in AC-coupled or polarity-agnostic paths like data lines or transformer secondaries. The P6SMB220AHE3/5B exhibits forward conduction behavior below ~0.7 V, while the CA version clamps symmetrically in both directions. Their VWM, VBR, and VC values differ accordingly.
What is the maximum operating temperature for the P6SMB220AHE3/5B?
The P6SMB220AHE3/5B has a maximum junction temperature (TJ max) of +150 °C and an operating junction/storage temperature range of –65 °C to +150 °C. This enables deployment in under-hood automotive locations and industrial enclosures with elevated ambient temperatures. Derating curves in Figure 2 of the datasheet specify allowable power reduction above 25 °C ambient, ensuring safe operation within thermal limits when mounted on recommended 0.2" × 0.2" copper pads.
