Product details
Overview
P4KE300C-E3/54 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 256 V standoff voltage (VWM), 285–315 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 μs), and clamps to ≤414 V at 1.0 A peak pulse current - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P4KE300C-E3/54 datasheet, P4KE300C-E3/54 pinout, P4KE300C-E3/54 application, or P4KE300C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and compliance with 10/1000 μs surge waveform standards.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling robust suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM) across -55 °C to +175 °C operating range.
The P4KE300C-E3/54 delivers 400 W peak pulse power under standardized 10/1000 μs waveform conditions, with clamping voltage tightly bounded at ≤414 V at rated IPPM. Its thermal design supports lead-mounted operation with RθJA = 100 °C/W and RθJL = 66 °C/W, making it suitable for PCB-level transient hardening without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 256 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 285–315 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | ≤414 V at IPPM = 1.0 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 400 W - Sustained transient energy absorption capacity per single 10/1000 μs event; defines surge handling class. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimal standby current; preserves signal integrity and power efficiency in high-impedance circuits. |
| TJ max. | +175 °C - Maximum junction temperature rating; enables deployment in under-hood automotive and industrial environments. |
| RθJL | 66 °C/W - Junction-to-lead thermal resistance; informs PCB copper pour requirements for sustained pulse duty cycling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ280CA | Surface-mount SMB package; 280 V VWM; 300 W PPPM; lower clamping (≤457 V at 0.87 A). | Requires PCB redesign for SMT layout; better suited for space-constrained consumer electronics vs. through-hole industrial designs. | Select when board real estate is limited and automated assembly is preferred; verify thermal pad design for 300 W pulse handling. |
| 1.5KE300CA | Higher PPPM (1500 W); same DO-41 package; 256 V VWM; clamps to ≤486 V at 3.1 A. | Over-spec'd for 400 W use cases; larger junction capacitance may affect high-speed signal lines. | Choose only where legacy 1.5KE footprint compatibility is required and higher surge margin justifies added cost and size. |

FAQ
What does the "C" suffix indicate in P4KE300C-E3/54?
The "C" in P4KE300C-E3/54 denotes bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P4KE300A), the P4KE300C-E3/54 has no cathode marking and functions identically in either polarity, making it ideal for AC-coupled or differential signal lines where polarity cannot be guaranteed. This is confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications".
Is P4KE300C-E3/54 AEC-Q101 qualified?
Yes, P4KE300C-E3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 16-Sep-2021 (Document Number: 88365), footnote (1) under "RATINGS AND CHARACTERISTICS CURVES". The HE3 suffix variant (e.g., P4KE300CHE3/54) is designated for AEC-Q101, but the E3/54 version - while RoHS-compliant and commercial-grade - shares identical die and construction; qualification applies to the P4KE300C family. Always verify latest qualification status via Vishay's official product page.
What is the maximum clamping voltage for P4KE300C-E3/54 under standard test conditions?
The maximum clamping voltage (VC) for P4KE300C-E3/54 is 414 V, measured at a peak pulse current (IPPM) of 1.0 A using the standardized 10/1000 μs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table on page 2 of the Vishay datasheet (Document Number: 88365). It represents the upper limit of voltage imposed on the protected circuit during a worst-case surge event.
Can P4KE300C-E3/54 be used in place of P4KE300A-E3/54?
No - P4KE300C-E3/54 and P4KE300A-E3/54 are not interchangeable without circuit review. The "C" suffix indicates bidirectional operation, while "A" denotes unidirectional with cathode marking. Substituting P4KE300C-E3/54 for P4KE300A-E3/54 in a DC-biased circuit may cause unintended conduction during normal operation. Always confirm polarity requirements and validate clamping behavior in the target application before substitution.
What is the thermal resistance specification for P4KE300C-E3/54?
P4KE300C-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 lead length = 10 mm), per the "THERMAL CHARACTERISTICS" table on page 3 of the Vishay datasheet. These values govern thermal derating above 25 °C ambient and inform PCB copper pour design - especially critical for repeated surge events in enclosed industrial enclosures.
