Product details
Overview
P6KE220HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 209 V minimum breakdown voltage (VBR), 185 V maximum stand-off voltage (VWM), 328 V clamping voltage (VC) at 1.8 A peak pulse current, 600 W peak pulse power rating with 10/1000 μs waveform, and AEC-Q101 qualification for automotive-grade reliability - deployed in engine control units and battery management systems.
For engineers reviewing the P6KE220HE3/54 datasheet, P6KE220HE3/54 pinout, P6KE220HE3/54 application, or P6KE220HE3/54 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJL = 20 °C/W), RoHS-compliant matte tin plating, DO-204AC (DO-15) package compatibility, and AEC-Q101 qualification status for automotive electronics design-in.
Technical Context
The P6KE220HE3/54 operates as a uni-directional avalanche diode, triggering when reverse voltage exceeds its 209–231 V breakdown range at 1 mA test current. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at 185 V), while fast response time (<1.0 ns) enables suppression of ESD and lightning-induced transients before downstream IC damage occurs.
Thermal design relies on low junction-to-lead resistance (20 °C/W), enabling effective heat dissipation into PCB copper during repetitive surges. The device sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and maintains clamping integrity up to 175 °C junction temperature - critical for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 | Lower peak pulse power (400 W), SMA package (surface-mount), higher VC (356 V @ 1.7 A) | Preferred for space-constrained PCBs where reflow assembly is required; not AEC-Q101 qualified | Select when automated assembly and footprint reduction outweigh automotive qualification needs |
| 1.5KE220A | Same DO-15 package, higher PPPM (1500 W), larger VBR spread (209–253 V), no AEC-Q101 qualification | Suitable for industrial power supplies requiring higher surge margin but lacking automotive environmental validation | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated and 1500 W headroom is needed |
Compared with SMAJ220A and 1.5KE220A, the P6KE220HE3/54 uniquely balances AEC-Q101 qualification, 600 W surge capacity, and DO-15 through-hole manufacturability - making it optimal for automotive Tier 2 suppliers needing drop-in replacement capability and traceable sourcing.

FAQ
What is the clamping voltage of the P6KE220HE3/54 under standard surge conditions?
The P6KE220HE3/54 exhibits a maximum clamping voltage (VC) of 328 V when subjected to a 10/1000 μs waveform at 1.8 A peak pulse current. This value is measured per JEDEC standards and represents the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6KE220HE3/54 suitable for automotive applications?
Yes, the P6KE220HE3/54 carries AEC-Q101 qualification, confirming its suitability for automotive applications including engine control units, body control modules, and ADAS sensor interfaces. Its 175 °C maximum junction temperature, thermal resistance of 20 °C/W, and validation across temperature cycling and humidity bias tests meet stringent automotive reliability requirements.
How does the HE3 suffix differ from the E3 suffix in P6KE220HE3/54?
The HE3 suffix in P6KE220HE3/54 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS compliance and JESD 201 Class 1A whisker testing only. Both share DO-204AC packaging and identical electrical specs, but HE3 is mandatory for automotive production programs requiring certified reliability.
What is the standoff voltage rating for P6KE220HE3/54?
The P6KE220HE3/54 has a maximum steady-state reverse standoff voltage (VWM) of 185 V, meaning it remains in high-impedance state below this threshold with leakage current limited to ≤1.0 μA. This allows safe integration into 125 V DC systems such as commercial HVAC controls or telecom power distribution without false triggering.
Can P6KE220HE3/54 be used in bi-directional configurations?
No, P6KE220HE3/54 is a uni-directional TVS diode, identifiable by the cathode band marking. For bi-directional protection, Vishay specifies the CA-suffixed variant (e.g., P6KE220CA). Using P6KE220HE3/54 in reverse-biased AC applications risks catastrophic failure due to lack of symmetrical avalanche characteristics.
