Product details
Overview
P4KE220-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 209 V minimum breakdown voltage (VBR), 185 V maximum standoff voltage (VWM), 328 A peak pulse current (IPPM), and clamps transients to ≤328 V at rated surge, protecting sensitive ICs and MOSFETs in industrial power supplies.
For engineers reviewing the P4KE220-E3/54 datasheet, P4KE220-E3/54 pinout, P4KE220-E3/54 application, or P4KE220-E3/54 equivalent, key selection criteria include its 400 W 10/1000 μs peak pulse power rating, AEC-Q101 qualification (E3 suffix denotes commercial grade), glass-passivated junction, and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamping device that remains high-impedance below VWM (185 V) and transitions rapidly to low-impedance conduction above VBR (209–231 V) during transient events. Its unidirectional polarity-marked with a cathode band-enables integration into DC-biased circuits without reverse leakage concerns under normal operation.
The device uses a glass-passivated silicon junction for stable avalanche characteristics and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 μs surges at 0.01% duty cycle. Thermal resistance values (RθJL = 66 °C/W, RθJA = 100 °C/W) define its derating behavior above 25 °C ambient, supporting reliable operation up to TJ = 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 185 V maximum - defines highest continuous DC operating voltage before leakage exceeds 1 μA |
| VBR (min/max) | 209 V / 231 V at 1 mA - ensures predictable avalanche onset within tight tolerance for precise protection thresholding |
| VC @ IPPM | ≤328 V at 328 A - clamping voltage limits downstream component stress during worst-case 400 W transient |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform, defining surge energy absorption capability |
| IFSM | 40 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for inrush or fault-current scenarios |
| TJ max. | 175 °C - maximum junction temperature enabling use in high-ambient industrial environments |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. Cathode identified by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Surface-mount SMB package (vs. through-hole DO-41); same VWM/VBR range but lower IPPM (171 A vs. 328 A) and PPPM (600 W vs. 400 W) | Requires PCB redesign for SMT placement; better suited for space-constrained consumer electronics vs. industrial through-hole assemblies | Select when board real estate is limited and surge energy is lower; verify thermal pad layout for 600 W rating |
| 1.5KE220A | Same DO-41 package but higher PPPM (1500 W); wider VBR tolerance (209–253 V); higher VC (356 V) | Used where higher surge margin is required (e.g., outdoor telecom cabinets), but clamps less tightly than P4KE220-E3/54 | Choose for harsher environments needing greater energy headroom; accept higher clamping voltage trade-off |
Compared with SMBJ220A and 1.5KE220A, the P4KE220-E3/54 delivers optimal balance of through-hole manufacturability, tight 209–231 V VBR tolerance, and 328 V clamping-making it ideal for cost-sensitive industrial controls where precise voltage limiting and legacy assembly compatibility are prioritized.

FAQ
What is the maximum clamping voltage of the P4KE220-E3/54 under rated surge conditions?
The P4KE220-E3/54 has a maximum clamping voltage (VC) of 328 V at its rated peak pulse current (IPPM) of 328 A, measured using the standard 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The P4KE220-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the P4KE220-E3/54 suitable for automotive applications?
The P4KE220-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade qualification-not AEC-Q101. For automotive use, Vishay offers the P4KE220AHE3/54 variant (HE3 suffix), which is AEC-Q101 qualified. The P4KE220-E3/54 itself is appropriate for non-safety-critical automotive accessories or aftermarket systems where formal qualification is not mandated, but design validation remains the customer's responsibility.
What does the "-E3/54" suffix mean in P4KE220-E3/54?
In P4KE220-E3/54, "E3" denotes RoHS-compliant commercial-grade construction with JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 13-inch paper tape and reel containing 5500 units. This ordering format aligns with Vishay's standard delivery mode for DO-41 devices and ensures compatibility with automated through-hole insertion equipment.
How does the P4KE220-E3/54 compare to bidirectional TVS diodes like P4KE220CA?
The P4KE220-E3/54 is unidirectional and features a cathode band for polarity identification, making it suitable for DC-biased lines where reverse conduction must be blocked. In contrast, P4KE220CA is bidirectional with no polarity marking and symmetric clamping in both directions-used in AC or floating signal lines. The P4KE220-E3/54 exhibits lower leakage below VWM and avoids unintended conduction in DC applications where the P4KE220CA would conduct in reverse.
What is the thermal resistance profile of the P4KE220-E3/54?
The P4KE220-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W (with 10 mm lead length). These values govern its power derating above 25 °C ambient and inform heatsinking decisions. At 75 °C lead temperature, its steady-state power dissipation (PD) drops to 1.5 W, matching its rated specification. The P4KE220-E3/54 relies primarily on lead conduction for heat transfer, not PCB copper area.
