Product details
Overview
P4KE220A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 209 V to 231 V breakdown voltage (VBR), 185 V maximum working peak reverse voltage (VWM), and clamps transients up to 328 A at 328 V (VC) under 10/1000 μs waveform - deployed on power rails and signal lines in industrial motor drives and automotive ECUs.
For engineers reviewing the P4KE220A-E3/54 datasheet, P4KE220A-E3/54 pinout, P4KE220A-E3/54 application, or P4KE220A-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal derating above 25 °C, standoff voltage compatibility with DC bus levels, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, responding within <1 ps to transient overvoltages. Its unidirectional polarity (cathode marked) enables asymmetric clamping - conducting only during reverse overvoltage events while blocking forward current up to 3.5 V at 25 A.
Rated for 400 W peak pulse power (10/1000 μs), it sustains repetitive surges at 0.01 % duty cycle and exhibits low incremental surge resistance for stable clamping performance. Thermal resistance is 66 °C/W (junction-to-lead), enabling direct PCB trace heat sinking without heatsinks in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V to 231 V at 1.0 mA test current - defines minimum voltage at which avalanche conduction begins, critical for ensuring clamping occurs above normal operating rail. |
| VWM | 185 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA; must exceed system DC operating voltage by ≥10 % for reliable blocking. |
| VC @ IPPM | 328 V at 328 A peak pulse current - clamping voltage under standardized 10/1000 μs surge; determines maximum stress imposed on downstream circuitry. |
| PPPM | 400 W - peak pulse power handling capability; defines transient energy absorption limit per event without degradation. |
| IFSM | 40 A - non-repetitive forward surge current (8.3 ms half-sine); relevant only if used in forward-biased configurations like crowbar circuits. |
| TJ max. | 175 °C - maximum junction temperature; supports operation in under-hood automotive environments and high-ambient industrial enclosures. |
| RθJL | 66 °C/W - junction-to-lead thermal resistance; enables thermal design using PCB copper area as heatsink, reducing need for external thermal management. |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded molded epoxy case with matte tin-plated leads. Cathode indicated by color band; anode is unmarked end. Compliant with UL 94 V-0 flammability rating and JESD 22-B106 soldering standard (275 °C, 10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward current entry / reverse voltage reference | Connected to lower-potential node (e.g., ground or return path); establishes polarity for unidirectional clamping action. |
| Cathode (banded lead) | Avalanche conduction terminal / clamping node | Connected to protected line (e.g., 24 V rail or CAN_H); conducts when reverse voltage exceeds VWM, shunting surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics over lifetime and temperature; eliminates surface contamination-induced parameter drift. |
| 400 W peak pulse power (10/1000 μs) | Supports protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without cascading failure in 24–48 V systems. |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive electronic control units requiring zero defects in harsh thermal and vibration environments. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage overshoot during fast transients, preserving margin below IC absolute maximum ratings. |
| 1.0 μA max reverse leakage @ VWM | Prevents excessive standby power loss in battery-powered or energy-sensitive applications such as telematics modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | DO-214AA package; 200 W peak power; lower VC = 308 V at same IPPM; higher capacitance (~100 pF vs ~50 pF). | Better suited for space-constrained SMT layouts; less effective for high-energy surges due to lower PPPM. | Select SMBJ220A when board real estate is limited and surge energy is ≤200 W; verify thermal pad layout meets RθJA requirements. |
| 1.5KE220A | Same DO-41 package; 1500 W peak power; higher VBR (209–231 V); VC = 308 V at 4.9 A (not 328 A); larger junction area. | Designed for higher-energy transients (e.g., AC mains coupling); not AEC-Q101 qualified. | Choose 1.5KE220A for industrial AC-input front-end protection where energy exceeds 400 W; avoid in automotive due to lack of qualification. |
Compared with SMBJ220A and 1.5KE220A, P4KE220A-E3/54 delivers optimal balance of AEC-Q101 compliance, 400 W surge handling, and DO-41 through-hole manufacturability - making it preferred for automotive and industrial control boards requiring proven reliability and legacy assembly compatibility.

FAQ
What is the maximum clamping voltage of the P4KE220A-E3/54 under a 10/1000 μs surge?
The P4KE220A-E3/54 clamps to a maximum of 328 V when subjected to its rated peak pulse current of 328 A under the standardized 10/1000 μs waveform. This value is measured at the device terminals and represents the upper bound of voltage seen by protected circuitry during worst-case transient events. Designers must ensure this clamping level remains below the absolute maximum voltage rating of downstream components by at least 20 % margin.
Is the P4KE220A-E3/54 suitable for automotive applications?
Yes, the P4KE220A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive electronic control units including body control modules, lighting drivers, and power distribution units. The E3 suffix denotes RoHS-compliant commercial grade with JESD 201 class 1A whisker testing, and its 175 °C maximum junction temperature supports under-hood deployment. Full qualification documentation is available from Vishay upon request.
How does the P4KE220A-E3/54 differ from bidirectional TVS diodes like P4KE220CA?
The P4KE220A-E3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P4KE220CA is bidirectional with no marking and symmetrical clamping in both directions. Unidirectional variants offer lower leakage (<1.0 μA at VWM) and slightly tighter VBR tolerance, making them ideal for DC rail protection. Bidirectional types are reserved for AC-coupled or differential signal lines like RS-485 or CAN where polarity reversal occurs.
What is the thermal resistance and how does it affect PCB layout for the P4KE220A-E3/54?
The P4KE220A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, meaning each watt dissipated raises the junction temperature by 66 °C above lead temperature. To manage power dissipation during repetitive surges, PCB traces connected to both leads should be widened (≥2 mm) and thermally relieved to internal copper planes. Avoid narrow traces or isolated pads that impede heat flow from the DO-41 body.
Can the P4KE220A-E3/54 be used in parallel for higher surge current handling?
No, the P4KE220A-E3/54 is not recommended for parallel operation due to mismatch in avalanche voltage (VBR tolerance ±5 %) causing current imbalance and premature failure of the lower-VBR unit. For higher surge capacity, select a single higher-rated device such as 1.5KE220A or use a TVS array with matched characteristics. Parallel use voids AEC-Q101 qualification and violates Vishay's application guidance.
