Product details
Overview
P6KE300-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 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, 600 W peak pulse power rating (10/1000 µs waveform), and DO-204AC (DO-15) axial package. It is used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients in industrial power supplies.
For engineers reviewing the P6KE300-E3/54 datasheet, P6KE300-E3/54 pinout, P6KE300-E3/54 application, or P6KE300-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, standoff voltage compatibility with nominal rail voltage (e.g., 256 VWM for 240 VAC-derived DC bus), thermal derating above 25 °C, and AEC-Q101 qualification status - though P6KE300-E3/54 is commercial-grade (E3 suffix), not HE3.
Technical Context
This TVS operates as a voltage-clamped crowbar device: under normal bias it presents <1.0 µA reverse leakage at 256 VWM, then rapidly avalanches near 300 V to limit transient energy. Its glass-passivated junction enables fast response (<1 ns) and stable breakdown with ±5% tolerance and +0.110 %/°C temperature coefficient.
It is rated for 600 W non-repetitive surge dissipation (10/1000 µs), 5.0 W steady-state power on infinite heatsink at TL = 75 °C, and withstands 100 A 8.3 ms half-sine forward surge. Thermal resistance is 20 °C/W junction-to-lead, enabling direct PCB trace heat sinking without external heatsinks in moderate-duty applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 285 V / 315 V at 1.0 mA - defines reliable avalanche initiation window; ensures clamping begins before protected circuit exceeds 300 V rating |
| VWM | 256 V - maximum continuous reverse operating voltage; must exceed system's peak DC rail (e.g., 240 VAC rectified + ripple) |
| VC @ IPPM | 414 V at 1.4 A - clamping voltage under 600 W surge; determines worst-case stress on downstream components |
| IPPM | 1.4 A - peak pulse current capability for 10/1000 µs waveform; defines minimum series impedance needed to limit current into device |
| PPPM | 600 W - surge power handling capacity; validates suitability for IEC 61000-4-5 Level 3 (1 kV/2 Ω) or similar transients |
| TJ max. | 175 °C - maximum junction temperature; supports operation in enclosed industrial enclosures up to 125 °C ambient with proper layout |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance; allows effective conduction cooling via PCB copper pour connected to cathode/anode leads |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with matte tin-plated leads. Cathode identified by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Reverse-biased reference terminal | Connected to ground or low-impedance return path; establishes reference for clamping action during positive transients |
| Cathode (non-banded end) | Transient voltage sensing node | Connected to protected line (e.g., +VDC rail); avalanche conduction shunts surge current to anode when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics over 1000+ surge events without parameter drift or degradation |
| 600 W peak pulse power (10/1000 µs) | Validates robustness against common industrial surge standards including IEC 61000-4-5 and ISO 7637-2 Pulse 1/2a |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response), reducing stress on downstream MOSFET gate oxides |
| AEC-Q101 qualified variants available (HE3 suffix) | Confirms reliability for automotive under-hood environments; P6KE300-E3/54 is commercial grade but shares identical die and package |
| RoHS-compliant (E3 suffix) | Meets JEDEC JS709A halogen-free requirements and EU Directive 2011/65/EU; suitable for green manufacturing programs |
Applications
| Industrial Power Supply Protection | Automotive ECU Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ300A | Same VBR (285–315 V), but SMC package (DO-214AB); 600 W rating, lower RθJA (40 °C/W vs. 75 °C/W) | Surface-mount footprint; better thermal performance in high-density layouts; requires reflow-compatible PCB design | Select SMBJ300A when board space is constrained and automated assembly is required; verify pad thermal relief for 5.0 W steady-state dissipation. |
| P6KE300A-E3/73 | Identical electrical specs and DO-204AC package; differs only in packaging format (73 = 1000 pcs ammo pack vs. 54 = 4000 pcs tape/reel) | No functional difference; same mounting, soldering, and circuit behavior | Choose P6KE300A-E3/73 for low-volume prototyping or manual assembly where reel handling is impractical. |
Compared with SMBJ300A and P6KE300A-E3/73, the P6KE300-E3/54 offers cost-optimized through-hole assembly, proven reliability in legacy industrial designs, and simplified hand-soldering - making it preferred for field-serviceable equipment and medium-volume production where axial lead placement is acceptable.

FAQ
What is the maximum clamping voltage of the P6KE300-E3/54 under standard test conditions?
The P6KE300-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 represents the worst-case voltage seen by downstream components during a full-power transient event. The P6KE300-E3/54 maintains this clamping performance across its specified operating temperature range of –55 °C to +175 °C.
Is the P6KE300-E3/54 suitable for automotive applications requiring AEC-Q101 qualification?
The P6KE300-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade construction. It is not AEC-Q101 qualified; that designation applies only to HE3-suffixed variants (e.g., P6KE300AHE3/54). While the P6KE300-E3/54 shares identical die and package with its HE3 counterpart, the E3 version lacks the extended reliability testing required for under-hood automotive use. For AEC-Q101 compliance, specify P6KE300AHE3/54 instead of P6KE300-E3/54.
How does the standoff voltage (VWM) of 256 V relate to system-level design for a 240 VAC input?
The P6KE300-E3/54's 256 V standoff voltage (VWM) is selected to safely exceed the peak rectified voltage of a 240 VAC supply (≈339 V) only after accounting for derating margins - but in practice, it is intended for DC bus protection downstream of bulk capacitance where ripple is minimized. For direct AC-line protection, a higher VWM device would be required. The P6KE300-E3/54 is correctly applied on stabilized DC rails where nominal voltage remains ≤256 V, ensuring <1.0 µA leakage and no false triggering.
Can the P6KE300-E3/54 be used in bidirectional configurations?
No - the P6KE300-E3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., P6KE300CA). Using the P6KE300-E3/54 in reverse-biased AC applications will result in forward conduction and permanent failure. Always match the device polarity to the expected transient direction: P6KE300-E3/54 for positive-only surges referenced to ground; P6KE300CA for symmetrical AC or differential-line protection.
What is the thermal resistance and how does it affect PCB layout for the P6KE300-E3/54?
The P6KE300-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from the silicon die to the PCB copper via its axial leads. To maximize thermal performance, both leads should connect to wide, thermally relieved copper pours - especially the cathode, which carries surge current. Avoid narrow traces; use ≥2 mm trace width and multiple vias to internal ground planes. This layout ensures the P6KE300-E3/54 sustains its 5.0 W power rating without exceeding 175 °C junction temperature.
