Product details
Overview
P6KE22CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 20.9–23.1 V breakdown voltage at 1 mA, 18.8 V stand-off voltage, 30.6 V maximum clamping voltage at 19.6 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE22CHE3/73 datasheet, P6KE22CHE3/73 pinout, P6KE22CHE3/73 application, or P6KE22CHE3/73 equivalent, this device is selected for robust ESD and surge protection in automotive body control modules, industrial sensor interfaces, and DC power input stages where fast response (<1 ns), low clamping ratio (1.63×VWM), and 175 °C junction temperature capability are critical.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 18.8 V), but avalanches within nanoseconds when transient voltage exceeds VBR, diverting surge current to ground while limiting downstream voltage to ≤30.6 V. Its glass-passivated junction ensures stable leakage (<1 μA at VWM) and repeatable breakdown characteristics across temperature.
The device uses a single PN junction structure with no internal series resistance or integrated control logic - its behavior is defined solely by avalanche physics and thermal mass. Derating curves confirm usable operation up to 175 °C junction temperature, with thermal resistance RθJL = 20 °C/W enabling direct PCB trace heat sinking without external heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 20.9 V / 23.1 V at 1 mA - defines minimum guaranteed avalanche initiation threshold and maximum variation across production lot |
| VWM | 18.8 V - maximum continuous reverse operating voltage before significant leakage begins; sets safe DC rail margin |
| VC @ IPPM | 30.6 V at 19.6 A - clamping voltage during worst-case 600 W surge; determines protected circuit's maximum transient exposure |
| PPPM | 600 W (10/1000 μs waveform) - peak surge energy handling capacity; validates suitability for IEC 61000-4-5 Level 4 (4 kV) testing |
| TJ max | 175 °C - enables deployment in under-hood automotive environments and high-ambient industrial enclosures without derating |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance allows effective self-heating management via copper pour on cathode pad |
| AEC-Q101 | Qualified - certified for automotive applications including engine control units, lighting drivers, and infotainment power supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/57T | Lower peak power (400 W), smaller SMA package (DO-214AC), 20.9–23.1 V VBR, 35.5 V VC @ 11.3 A | Higher clamping voltage (35.5 V vs. 30.6 V) and lower surge current rating limit use to lower-energy interfaces like RS-485 or CAN | Select when board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 3 (2 kV) |
| 1.5KE22A | Same DO-15 package, identical VBR and VWM, but 1.5 kW peak power (10/1000 μs), 30.6 V VC @ 49.2 A | Higher energy handling supports repeated load-dump events in alternator-regulated systems without thermal runaway | Select when protecting high-current DC distribution nodes where multi-pulse surge endurance is required |
Compared with SMAJ22A-E3/57T, P6KE22CHE3/73 delivers 50 % higher surge energy absorption and tighter clamping for cost-sensitive automotive and industrial power rails; compared with 1.5KE22A, it trades peak power for AEC-Q101 qualification and optimized thermal performance in sustained transient environments.

FAQ
What is the clamping voltage of P6KE22CHE3/73 under maximum surge conditions?
The P6KE22CHE3/73 clamps to a maximum of 30.6 V when subjected to its rated peak pulse current of 19.6 A (10/1000 μs waveform). This value is measured per JEDEC standards and represents the upper bound of voltage seen by protected circuitry during worst-case transient events, ensuring compatibility with 3.3 V and 5 V logic interfaces when properly laid out.
Is P6KE22CHE3/73 suitable for automotive applications?
Yes, P6KE22CHE3/73 is AEC-Q101 qualified and specifically rated for automotive use. Its 175 °C maximum junction temperature, robust glass-passivated junction, and validation across temperature cycling, mechanical shock, and humidity tests make it appropriate for body control modules, lighting drivers, and infotainment power supplies where reliability under harsh conditions is essential.
How does the HE3 suffix affect P6KE22CHE3/73 specifications?
HE3 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It does not alter electrical parameters - VBR, VC, and PPPM remain identical to non-HE3 variants - but guarantees enhanced process control and reliability screening for automotive and industrial deployments requiring extended lifetime and zero-field failures.
What is the thermal resistance of P6KE22CHE3/73 and how does it impact layout?
P6KE22CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. This allows efficient heat transfer from the silicon die to the PCB through the cathode lead, so designers should maximize copper area connected to the cathode pad - ideally ≥100 mm² - to maintain junction temperature below 175 °C during repetitive surge events without forced cooling.
Can P6KE22CHE3/73 be used in bi-directional protection circuits?
No, P6KE22CHE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and presence of a cathode band. For bi-directional protection, Vishay offers the P6KE22CA variant, which lacks polarity marking and provides symmetrical clamping in both directions - using P6KE22CHE3/73 in AC or floating applications risks forward conduction and failure during negative transients.
