Product details
Overview
P6KE22CHE3/54 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 a 20.9 V minimum breakdown voltage (VBR), 18.8 V maximum stand-off voltage (VWM), 30.6 V clamping voltage (VC) at 19.6 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE22CHE3/54 datasheet, P6KE22CHE3/54 pinout, P6KE22CHE3/54 application, or P6KE22CHE3/54 equivalent, this device is selected for robust ESD and surge protection in automotive body electronics, industrial sensor interfaces, and DC power input stages where fast response (<1 ns), low clamping ratio (VC/VWM ≈ 1.63), and high surge current tolerance are critical.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <1 μA leakage at 18.8 V; when transient voltage exceeds VBR (20.9–23.1 V), it avalanches into low-impedance conduction within <1 ns to limit downstream voltage to ≤30.6 V. Its glass-passivated junction ensures stable parametric performance across temperature (−55 °C to +175 °C) and long-term reliability under repetitive surges.
The device uses a single PN junction structure with cathode-band polarity marking, rated for 100 A non-repetitive forward surge (8.3 ms half-sine), 5.0 W steady-state power dissipation on infinite heatsink, and thermal resistance of 20 °C/W (junction-to-lead), enabling direct PCB trace heat sinking in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 18.8 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets safe DC rail margin for 24 V systems. |
| VBR (min/max) | 20.9 V / 23.1 V at 1 mA - Confirmed avalanche onset range; defines minimum trigger threshold for transient suppression. |
| VC @ IPPM | 30.6 V at 19.6 A (10/1000 μs) - Clamped voltage seen by protected IC during worst-case surge; determines downstream voltage stress. |
| PPPM | 600 W - Peak transient energy handling capacity; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge testing. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| AEC-Q101 | Qualified - Validated for automotive applications including temperature cycling, HTRB, and ESD per JESD22-A114. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with UL 94 V-0 molded epoxy and matte tin-plated leads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Same VWM (18.8 V), lower PPPM (400 W), SMA package (surface-mount) | Preferred for space-constrained PCBs; lacks AEC-Q101 qualification and higher surge margin. | Select SMAJ22A only if board area is critical and automotive qualification is not required. |
| 1.5KE22A | Same VWM/VBR, identical DO-204AC package, but commercial-grade (non-AEC-Q101), 1.5 kW PPPM | Higher surge rating suits industrial mains-connected equipment; not validated for automotive temperature cycling. | Choose 1.5KE22A for cost-sensitive industrial designs where AEC-Q101 is unnecessary and 1.5 kW surge headroom is beneficial. |
Compared with SMAJ22A and 1.5KE22A, P6KE22CHE3/54 uniquely balances AEC-Q101 compliance, 600 W surge capability, and DO-15 through-hole manufacturability-making it optimal for automotive and industrial applications requiring proven reliability and ease of assembly.

FAQ
What is the maximum clamping voltage of P6KE22CHE3/54 under standard test conditions?
The maximum clamping voltage (VC) of P6KE22CHE3/54 is 30.6 V, measured at 19.6 A peak pulse current with a 10/1000 μs waveform. This value represents the highest voltage that will appear across the protected circuit during a standardized surge event, ensuring downstream components remain within safe operating limits. The P6KE22CHE3/54 achieves this clamping performance while maintaining low leakage and fast response.
Is P6KE22CHE3/54 suitable for automotive applications?
Yes, P6KE22CHE3/54 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD22 standards. Its −55 °C to +175 °C operating junction temperature range and DO-204AC package with matte tin leads make it appropriate for under-hood and cabin automotive modules. The P6KE22CHE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product documentation.
What does the "HE3" suffix indicate in P6KE22CHE3/54?
"HE3" denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. The "H" confirms AEC-Q101 qualification, "E3" indicates RoHS compliance and JESD201 Class 1A whisker testing for base variants-while "HE3" upgrades to Class 2 for enhanced reliability in high-vibration environments. This makes P6KE22CHE3/54 distinct from commercial-only variants like P6KE22A-E3.
How does P6KE22CHE3/54 compare to P6KE22A in terms of reliability and application scope?
P6KE22CHE3/54 is AEC-Q101 qualified and rated for automotive use, whereas P6KE22A is commercial-grade only. Both share identical electrical parameters (VWM, VBR, VC, PPPM), but P6KE22CHE3/54 undergoes additional qualification testing for temperature cycling, HTRB, and mechanical shock. For designs targeting automotive OEM or Tier-1 supply chains, P6KE22CHE3/54 is mandatory; P6KE22A remains suitable for non-automotive industrial or consumer applications.
What is the thermal resistance specification for P6KE22CHE3/54?
P6KE22CHE3/54 has a typical thermal resistance of 20 °C/W from junction to lead (RθJL) and 75 °C/W from junction to ambient (RθJA). This allows effective heat dissipation through PCB copper pours or chassis mounting, supporting continuous 5.0 W power dissipation when the lead temperature (TL) is maintained at 75 °C. These values are confirmed in Vishay's Thermal Characteristics table for the DO-204AC package used by P6KE22CHE3/54.
