Product details
Overview
P6KE300A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 300 V breakdown voltage (VBR = 285–315 V at 1.0 mA), 414 V maximum clamping voltage (VC) at 1.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, microcontrollers, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the P6KE300A-E3/54 datasheet, P6KE300A-E3/54 pinout, P6KE300A-E3/54 application, or P6KE300A-E3/54 equivalent, this device is selected for cost-sensitive commercial-grade surge protection where standoff voltage (VWM = 256 V), low leakage (<1.0 μA), and AEC-Q101–qualified reliability are critical - especially in industrial power supplies, automotive body electronics, and telecom line cards.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds its 285–315 V breakdown range. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1.0 ns).
Thermal design relies on its 20 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating; derating begins above 25 °C ambient, with full power (5.0 W) only sustainable at TL ≤ 75 °C. The 100 A IFSM rating supports single-event surge robustness without fuse coordination dependency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ300A | DO-214AA package; lower RθJA (50 °C/W); same VBR (285–315 V), VC = 430 V @ 1.3 A | Surface-mount layout; better thermal performance on PCB but requires reflow-compatible footprint | Select SMBJ300A when space-constrained PCBs demand SMD mounting and higher thermal efficiency is needed. |
| 1.5KE300A | Higher PPPM (1500 W); larger DO-201AD package; VC = 430 V @ 3.5 A; same VBR range | Higher-energy surge environments (e.g., AC mains input); not AEC-Q101 qualified | Choose 1.5KE300A for industrial AC-DC front-ends requiring >1 kW surge handling, accepting larger footprint. |
Compared with P6KE300A-E3/54, SMBJ300A offers superior thermal dissipation in SMT layouts but lacks axial-lead mechanical robustness, while 1.5KE300A delivers 2.5× pulse power at the cost of size and automotive qualification - making P6KE300A-E3/54 optimal for cost-sensitive, through-hole, AEC-Q101–required applications.

FAQ
What is the maximum clamping voltage of the P6KE300A-E3/54 under standard test conditions?
The P6KE300A-E3/54 has a maximum clamping voltage (VC) of 414 V when subjected to its rated peak pulse current of 1.4 A using the 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream components see no more than 414 V during transient events - a critical parameter for ensuring compatibility with 400 V-rated capacitors and 3.3 V/5 V logic interfaces protected by this device.
Is the P6KE300A-E3/54 suitable for automotive applications?
Yes, the P6KE300A-E3/54 is AEC-Q101 qualified (as indicated by the HE3 suffix variant), and the E3 suffix version meets JESD 201 Class 1A whisker resistance. While the base P6KE300A-E3/54 is commercial grade, its construction - including glass-passivated junction, UL 94 V-0 molding, and 175 °C junction rating - supports deployment in non-safety-critical automotive domains such as body control modules, HVAC actuators, and lighting drivers where transient immunity to ISO 7637-2 Pulse 5a is required.
How does the P6KE300A-E3/54 differ from bidirectional TVS diodes like P6KE300CA?
The P6KE300A-E3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6KE300CA is bidirectional with no polarity marking and symmetrical clamping in both directions. The P6KE300A-E3/54 provides lower forward voltage drop (VF = 5.0 V at 50 A) and is intended for DC rail protection, while P6KE300CA suits AC signal lines or floating buses. Their VBR ranges also differ: P6KE300A-E3/54 is 285–315 V, while P6KE300CA is not defined in this family beyond 440 V max.
What is the standoff voltage rating for the P6KE300A-E3/54, and why does it matter?
The standoff voltage (VWM) of the P6KE300A-E3/54 is 256 V - the maximum continuous reverse voltage it can block without exceeding 1.0 μA leakage current. This rating ensures reliable operation on 240 VAC-derived DC rails or 200–250 V DC systems, preventing false triggering during normal operation while maintaining sufficient margin below the 285 V minimum breakdown voltage. Exceeding VWM risks accelerated aging or premature conduction.
Can the P6KE300A-E3/54 be used in parallel for higher surge current handling?
No - the P6KE300A-E3/54 is not characterized for parallel operation due to VBR tolerance (±5%) causing current imbalance during clamping. Uneven sharing may result in one device absorbing >80% of the surge, leading to thermal runaway and failure. For higher IPPM, select a single higher-rated device (e.g., 1.5KE300A) or implement staged protection with upstream current-limiting resistors and coordinated clamping thresholds.
