Product details
Overview
P6KE24CHE3/54 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 600 W peak pulse power (10/1000 μs), 22.8 V to 25.2 V breakdown voltage at 1 mA, 20.5 V stand-off voltage, 33.2 V maximum clamping voltage at 18.1 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE24CHE3/54 datasheet, P6KE24CHE3/54 pinout, P6KE24CHE3/54 application, or P6KE24CHE3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (20 °C/W junction-to-lead), surge current capability under 8.3 ms half-sine waveform, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This device operates as a voltage-clamping protector: under normal conditions it presents high impedance (>1 MΩ leakage at 20.5 V), but avalanches rapidly when transient voltage exceeds VBR, limiting downstream voltage to ≤33.2 V at 18.1 A. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
The P6KE24CHE3/54 is rated for -55 °C to +175 °C operating junction temperature, with thermal derating starting above 25 °C ambient. Its 20 °C/W RθJL enables effective heat transfer to PCB copper or lead frame, supporting repetitive surge handling up to 0.01% duty cycle when properly mounted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 22.8 V min / 25.2 V max at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Stand-off Voltage VWM | 20.5 V - maximum continuous working voltage before leakage exceeds 1 μA; sets safe DC rail margin |
| Clamping Voltage VC | 33.2 V at 18.1 A IPPM - limits transient voltage seen by protected IC, critical for I/O pin survivability |
| Peak Pulse Power | 600 W (10/1000 μs) - sustains high-energy surges without failure; validated per Fig. 1 derating curve |
| Junction Temperature Range | -55 °C to +175 °C - supports under-hood automotive and industrial environments with no derating loss at full range |
| Thermal Resistance RθJL | 20 °C/W - enables efficient heat conduction to PCB traces or heatsinked leads for repetitive surge handling |
| AEC-Q101 Qualified | Yes - certified for automotive electronics per stress test requirements including HTOL, TCT, and ESD HBM ≥8 kV |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; forms clamping path during positive transients on cathode side |
| Cathode | High-side connection point | Connected to protected line (e.g., 24 V rail or CAN_H); avalanche conduction occurs when cathode voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |

| 600 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 1 (inductive switch-off) and IEC 61000-4-5 Combination Wave surges without degradation |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero field failure risk |
| Low clamping ratio (VC/VBR ≈ 1.35) | Minimizes voltage overshoot during surge events, preserving margin below 36 V absolute max ratings of common 24 V logic ICs |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability for safety-critical assemblies |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 24 V supply inputs of engine control units (ECUs) against load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed between battery feed and input filter capacitor; responds within <1 ns to suppress >100 V transients.

Use Scenario: Shielding gate drivers in washing machine motor inverters from back-EMF spikes during brushless DC motor commutation. IC Role / Device Role / Timing Role: Parallel clamp across half-bridge high-side MOSFET source-drain; diverts inductive kickback away from driver IC. Use Value: Clamps 200 V+ spikes to 33.2 V within nanoseconds, eliminating need for snubbers and reducing component count in compact appliance designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Same VWM (20.5 V) and VC (38.9 V), but lower PPPM (400 W) and smaller SMA package (RθJA = 110 °C/W vs. 75 °C/W) | Limited to low-power consumer electronics; unsuitable for automotive or industrial surge repetition | Select only for space-constrained non-automotive designs where 400 W surge capacity suffices |
| 1.5KE24A | Higher PPPM (1500 W), same DO-15 package, but larger footprint (1.25" length vs. 1.0") and no AEC-Q101 qualification | Used in legacy industrial power supplies; lacks automotive qualification and tighter VBR tolerance | Choose when higher single-pulse energy is required and automotive qualification is not mandated |
Compared with SMAJ24A and 1.5KE24A, P6KE24CHE3/54 delivers optimal balance of AEC-Q101 compliance, 600 W surge rating, and DO-15 manufacturability-making it the preferred choice for new automotive and industrial designs requiring validated reliability and consistent clamping performance.

FAQ
What is the exact breakdown voltage range for P6KE24CHE3/54?
The P6KE24CHE3/54 has a guaranteed breakdown voltage range of 22.8 V to 25.2 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This tight ±5% tolerance ensures predictable clamping behavior across production lots and temperature extremes, directly supporting design margin calculations for protected circuits.
Does P6KE24CHE3/54 meet automotive qualification standards?
Yes, P6KE24CHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay documentation. It has passed high-temperature operating life (HTOL), temperature cycling (TCT), and human-body model (HBM) ESD tests ≥8 kV-making it approved for use in automotive powertrain, body electronics, and ADAS subsystems.
What is the maximum clamping voltage of P6KE24CHE3/54 under surge conditions?
The maximum clamping voltage of P6KE24CHE3/54 is 33.2 V at 18.1 A peak pulse current (IPPM), tested with a 10/1000 μs waveform. This value represents the worst-case voltage imposed on protected circuitry during standardized surge events, enabling accurate selection of downstream components with appropriate voltage margins.
How does the thermal resistance of P6KE24CHE3/54 affect its surge handling capability?
P6KE24CHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. This low value allows rapid heat dissipation into PCB copper or lead frame, enabling repetitive surge operation at 0.01% duty cycle without exceeding 175 °C junction temperature-critical for automotive and industrial applications with frequent transients.
Is P6KE24CHE3/54 RoHS compliant and halogen-free?
Yes, P6KE24CHE3/54 meets RoHS Directive 2011/65/EU and JEDEC JS709A halogen-free standards. The HE3 suffix confirms matte tin plating compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance-ensuring compatibility with lead-free reflow processes and long-term reliability in harsh environments.
