Product details
Overview
P6KE220CHE3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for primary-level 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 (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability - deployed in engine control units and battery management interfaces.
For engineers reviewing the P6KE220CHE3/54 datasheet, P6KE220CHE3/54 pinout, P6KE220CHE3/54 application, or P6KE220CHE3/54 equivalent, this device serves as a robust, RoHS-compliant, DO-15 packaged TVS for transient suppression in automotive electronics, industrial sensor front-ends, and telecom line protection where bidirectional surge immunity and low leakage (<1 μA at VWM) are critical.
Technical Context
The P6KE220CHE3/54 operates as a bi-directional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or floating circuits without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.108 %/°C), while the 20 °C/W junction-to-lead thermal resistance supports reliable power dissipation under repetitive surge conditions.
Designed for 10/1000 μs waveform compliance, it delivers 328 V clamping at 1.8 A IPPM with <1 ns response time and 1.0 μA max reverse leakage at 185 V - meeting IEC 61000-4-5 Level 4 surge immunity requirements when properly laid out with minimized trace inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 185 V max - maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1 μA |
| VBR (min/max) | 209 V / 231 V at 1 mA - guaranteed avalanche initiation range defining protection threshold accuracy |
| VC @ IPPM | 328 V at 1.8 A - clamped voltage seen by protected circuit during 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W - peak surge power handling per 10/1000 μs waveform, enabling protection against lightning-induced surges |
| IPPM | 1.8 A - peak current capability before clamping exceeds 328 V, directly sizing series impedance for target energy absorption |
| TJ max | 175 °C - maximum junction temperature allowing operation in under-hood automotive environments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.300" lead spacing, UL 94 V-0 molded epoxy |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, non-polarized bi-directional device with no cathode marking; leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Lead 1 | Terminal for PCB mounting | Standard axial lead; requires ≥0.375" (9.5 mm) lead length for thermal derating compliance per Fig. 5 |
| Lead 2 | Terminal for PCB mounting | Second axial lead; symmetric with Lead 1; both leads serve identical electrical and thermal functions |
Key Features

| Glass passivated junction | Ensures long-term VBR stability and low parameter drift across temperature and lifetime |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) with appropriate PCB layout |
| Low clamping ratio (VC/VBR ≈ 1.57) | Minimizes overvoltage stress on protected MOSFETs, microcontrollers, or CAN transceivers during surge events |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability for high-reliability industrial use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same VWM (185 V) and VC (328 V), but SMC (DO-214AB) surface-mount package; 600 W rating retained | Requires rework of PCB layout for SMT assembly; better thermal performance due to lower RθJA (50 °C/W vs. 75 °C/W) | Select when automated assembly, higher board density, or improved thermal cycling reliability are required. |
| 1.5KE220CA | Same VBR range and bi-directionality, but higher 1500 W peak power; larger DO-201AD package; VF = 3.5 V | Over-specified for most 600 W applications; occupies more board space; suited for high-energy industrial surge zones | Choose only when legacy 1.5KE footprint compatibility or >1 kW surge margin is mandatory. |
Compared with SMBJ220CA and 1.5KE220CA, the P6KE220CHE3/54 offers optimal balance of cost, through-hole manufacturability, AEC-Q101 qualification, and proven field reliability in automotive and industrial power rail protection - without over-engineering for typical 600 W surge events.

FAQ
What is the polarity configuration of the P6KE220CHE3/54?
The P6KE220CHE3/54 is a bi-directional TVS diode with symmetrical avalanche characteristics - neither lead is marked as anode or cathode, and it clamps transients equally in both directions above ±209 V. This eliminates polarity concerns during placement and enables protection of AC-coupled or floating nodes without orientation checks. The "CA" suffix in the full part number explicitly denotes bi-directional functionality, confirmed in Vishay's 88369 datasheet Section 1.
Does the P6KE220CHE3/54 meet automotive qualification standards?
Yes, the P6KE220CHE3/54 carries the HE3 suffix, indicating AEC-Q101 qualification per Vishay's documentation. It is rated for operation from −55 °C to +175 °C junction temperature and has passed stress tests including HTRB, HTGB, and temperature cycling - making it suitable for under-hood engine control units, battery management systems, and ADAS sensor modules where automotive-grade reliability is mandated.
What is the maximum clamping voltage of the P6KE220CHE3/54 under surge conditions?
The P6KE220CHE3/54 has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88369 and defines the upper voltage limit imposed on protected circuitry during a 600 W transient event - critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the P6KE220CHE3/54 differ from the uni-directional P6KE220A variant?
The P6KE220CHE3/54 is bi-directional (denoted by "CA"), while P6KE220A is uni-directional ("A"). The bi-directional version clamps transients in both polarities and has no cathode band marking; the uni-directional version uses a cathode band and only clamps in reverse bias. Both share identical VBR, VWM, and VC specs, but P6KE220CHE3/54 is required for AC signal lines, transformer-coupled interfaces, or any application where voltage reversals occur.
What packaging and reel format is supplied for the P6KE220CHE3/54?
The P6KE220CHE3/54 ships in 13-inch diameter paper tape and reel format with a base quantity of 4000 pieces per reel (ordering code "/54"). The "HE3" suffix confirms AEC-Q101 qualification and RoHS compliance, while the DO-204AC (DO-15) package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards - verified in Vishay's ordering information table on page 3 of document 88369.
