Product details
Overview
P4KE220CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 185 V stand-off voltage (VWM), 209–231 V breakdown voltage (VBR) at 1 mA, 328 V maximum clamping voltage (VC) at 1.2 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and automotive ECUs against inductive switching surges.
For engineers reviewing the P4KE220CAHE3/54 datasheet, P4KE220CAHE3/54 pinout, P4KE220CAHE3/54 application, or P4KE220CAHE3/54 equivalent, this device is selected for robust bidirectional surge protection where AEC-Q101 qualification, low clamping ratio, and DO-41 through-hole compatibility are required in industrial and automotive subsystems.
Technical Context
The P4KE220CAHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling symmetrical clamping in both polarities without polarity marking. Its 10/1000 μs surge response delivers sub-nanosecond turn-on and low incremental surge resistance, critical for protecting sensitive inputs during load dump or ESD events.
Thermal design is supported by a typical junction-to-lead thermal resistance of 66 °C/W and operation up to 175 °C junction temperature. The device meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability requirements, confirming suitability for high-reliability automotive PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Avalanche conduction initiates within this range; ensures predictable turn-on under transient stress. |
| VC (Clamping Voltage) | 328 V at IPPM = 1.2 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines safe overvoltage margin for downstream ICs. |
| PPPM (Peak Pulse Power) | 400 W - Sustains single 10/1000 μs transients without failure; derates linearly above 25 °C ambient per Fig. 2. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Minimal standby power loss and signal integrity impact in high-impedance sensing paths. |
| TJ max | 175 °C - Enables use in under-hood automotive environments and industrial enclosures without forced cooling. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per AEC standard. |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads. RoHS-compliant and UL 94 V-0 rated. Lead length ≥ 10 mm for thermal derating calculations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (unmarked ends) | Bidirectional avalanche junction terminals | No polarity marking - symmetrical conduction in either direction; both leads serve as interchangeable surge current entry/exit points. |
| Lead 1 (Anode side) | Current input during positive transient | Conducts surge current into junction when voltage exceeds +VBR; same physical role as Lead 2 during negative transient. |
| Lead 2 (Cathode side) | Current input during negative transient | Conducts surge current into junction when voltage exceeds –VBR; functionally identical to Lead 1 due to bidirectional symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics over 1000+ surge events without parameter drift or degradation. |
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 3 (1 kV line-to-line) surge immunity without external series impedance in many 24 V systems. |
| AEC-Q101 qualification | Validates performance across –55 °C to +175 °C, including HTSL, TC, and mechanical shock - required for engine control modules and ADAS sensors. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected ICs compared to alternatives with ratios >1.6, extending lifetime of downstream logic and analog front-ends. |
| DO-41 mechanical robustness | Withstands 10 s solder dip at 275 °C and meets J-STD-002/JESD 22-B102 solderability standards for high-yield wave and reflow assembly. |
Applications

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 | Surface-mount SMB package (vs. DO-41 through-hole); same VWM/VBR/VC ratings; 600 W PPPM rating. | Better suited for space-constrained PCBs and automated SMT assembly; less robust mechanical retention than axial DO-41 in high-vibration environments. | Select SMBJ220CA when board real estate is limited and vibration exposure is low; verify thermal pad layout for 600 W derating. |
| 1.5KE220CA | Higher PPPM (1500 W) but larger DO-201 package; same VWM/VBR/VC; higher IFSM (200 A vs. 40 A). | Used where single-event surge energy exceeds 400 W capability - e.g., main power bus protection in heavy-duty vehicles. | Choose 1.5KE220CA only if system-level surge testing requires >400 W headroom; note increased footprint and lead inductance. |
Compared with SMBJ220CA and 1.5KE220CA, the P4KE220CAHE3/54 offers optimal balance of AEC-Q101 compliance, DO-41 mechanical ruggedness, and cost-effective 400 W protection for mid-tier automotive and industrial signal-line applications - without over-engineering for higher-power or SMT-only designs.

FAQ
What is the clamping voltage of P4KE220CAHE3/54 at its rated peak pulse current?
The P4KE220CAHE3/54 has a maximum clamping voltage (VC) of 328 V at a peak pulse current (IPPM) of 1.2 A with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88365 and defines the upper voltage limit imposed on protected circuits during standardized surge events. The P4KE220CAHE3/54 maintains this clamping performance across its qualified temperature range.
Is P4KE220CAHE3/54 suitable for automotive applications?
Yes, the P4KE220CAHE3/54 is AEC-Q101 qualified per the Vishay datasheet revision 16-Sep-2021, confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock. Its DO-41 package, 175 °C max junction temperature, and stable clamping behavior make the P4KE220CAHE3/54 appropriate for engine control, body electronics, and ADAS subsystems.
How does the bidirectional configuration of P4KE220CAHE3/54 affect its mounting and circuit integration?
The P4KE220CAHE3/54 has no polarity marking and conducts identically in both directions, so either lead may connect to line or ground without functional impact. This simplifies layout in AC-coupled or floating signal paths and eliminates orientation errors during manual or automated assembly - unlike unidirectional variants such as P4KE220A which require cathode-band alignment.
What is the maximum steady-state power dissipation for P4KE220CAHE3/54?
The P4KE220CAHE3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at TL = 75 °C, as specified in the "Maximum Ratings" table of datasheet 88365. In practice, derating applies above 25 °C ambient, and actual usable power depends on PCB copper area, lead length, and airflow - the P4KE220CAHE3/54 is not intended for continuous power regulation.
Does P4KE220CAHE3/54 meet RoHS and lead-free soldering requirements?
Yes, the HE3 suffix in P4KE220CAHE3/54 indicates RoHS-compliant construction and AEC-Q101 qualification. The device uses matte tin-plated leads compatible with J-STD-002 and JESD 22-B102 solderability standards, and withstands solder dip up to 275 °C for 10 seconds per JESD 22-B106 - fully supporting lead-free reflow and wave soldering processes.
