Product details
Overview
P6KE300CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 300 V breakdown voltage (VBR min/max = 285 V / 315 V), 414 V maximum clamping voltage at 1.4 A peak pulse current, 600 W peak pulse power rating with 10/1000 μs waveform, and operates across -55 °C to +175 °C junction temperature range - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE300CA-E3/54 datasheet, P6KE300CA-E3/54 pinout, P6KE300CA-E3/54 application, or P6KE300CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 414 V clamping voltage at rated IPPM, AEC-Q101 qualification status, and thermal resistance (RθJL = 20 °C/W) for board-level thermal design.
Technical Context
This device implements a silicon avalanche diode structure optimized for fast transient response (<1 ns) and low dynamic impedance during surge events. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal paths without polarity sensitivity.
It delivers 600 W peak pulse power handling per 10/1000 μs waveform at 25 °C, derating linearly above TA = 25 °C with 0.67 %/°C slope per Fig. 2, and maintains stable VBR temperature coefficient of +0.110 %/°C across its operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 285 V / 315 V at 1.0 mA test current - defines reliable conduction onset under bidirectional surge conditions |
| VWM | 256 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 414 V at 1.4 A peak pulse current - clamping voltage limiting downstream component stress |
| PPPM | 600 W - surge energy absorption capacity using standard 10/1000 μs waveform |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour sizing |
| TJ range | -55 °C to +175 °C - supports under-hood automotive and high-temp industrial environments |
| Package | DO-15 (DO-204AC) - industry-standard axial-leaded through-hole package with 0.250" lead spacing |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional operation; case meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminals | No functional distinction - either end connects to protected line; clamps equally in both directions |
| Lead 1 / Lead 2 | Current path terminals | Leads serve as mechanical attachment and thermal conduction path to PCB; RθJL = 20 °C/W assumes full lead soldering |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable long-term leakage performance and humidity resistance per JESD22-A110 |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out |
| AEC-Q101 qualified (HE3 variant); E3 is commercial grade | P6KE300CA-E3/54 is RoHS-compliant commercial version; HE3 suffix required for automotive qualification |
| Low incremental surge resistance | Ensures minimal voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a) |
| 175 °C max junction temperature | Permits operation in high-ambient environments such as motor control enclosures or power supply front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ300CA | DO-214AA package; 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W); same VBR/VC specs | Suitable for surface-mount layouts; requires rework of footprint and thermal relief | Select SMBJ300CA when space-constrained SMT assembly is required and board layout allows DO-214AA placement. |
| 1.5KE300CA | Higher 1500 W peak power; DO-201AD package; longer lead time; identical VBR, VC, and bidirectional behavior | Better suited for high-energy surge zones (e.g., AC mains entry) where 600 W is marginal | Choose 1.5KE300CA where legacy 1.5 kW surge standards apply or where higher single-pulse margin is mandated. |
Compared with SMBJ300CA and 1.5KE300CA, P6KE300CA-E3/54 offers optimal balance of proven through-hole reliability, cost efficiency, and adequate 600 W surge handling for mid-tier industrial and automotive signal line protection - without requiring PCB redesign or premium power rating.

FAQ
What is the clamping voltage of P6KE300CA-E3/54 at its rated peak pulse current?
The P6KE300CA-E3/54 has a maximum clamping voltage (VC) of 414 V when subjected to its rated peak pulse current (IPPM) of 1.4 A using the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and ensures predictable overvoltage limiting for downstream circuitry. The P6KE300CA-E3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE300CA-E3/54 suitable for automotive applications?
P6KE300CA-E3/54 is RoHS-compliant and manufactured to commercial-grade specifications. While it shares the same die and core characteristics as AEC-Q101-qualified variants (e.g., P6KE300CAHE3/54), the E3 suffix indicates it is not formally certified for automotive use. For production automotive systems, the HE3-suffixed version must be specified. The P6KE300CA-E3/54 remains appropriate for non-safety-critical automotive test equipment or aftermarket modules.
How does the bidirectional nature of P6KE300CA-E3/54 affect its circuit implementation?
The P6KE300CA-E3/54 has no polarity marking and conducts identically in both directions, making it ideal for AC-coupled lines, differential buses (e.g., RS-485), or floating sensor outputs. Unlike unidirectional TVS diodes, it eliminates orientation errors during manual assembly and provides symmetrical clamping without external biasing. Its VBR and VC values apply equally for positive and negative transients, simplifying schematic symbol usage and layout for the P6KE300CA-E3/54.
What is the thermal resistance specification for P6KE300CA-E3/54, and why does it matter?
P6KE300CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. RθJL is critical because it determines how effectively heat transfers from the silicon junction to the PCB copper via the leads during repetitive surge events. Proper soldering of both leads to wide copper pours minimizes thermal impedance, preventing junction overheating beyond the 175 °C limit - essential for sustained reliability of the P6KE300CA-E3/54 in high-duty-cycle applications.
Can P6KE300CA-E3/54 replace P6KE300A in a design?
No - P6KE300CA-E3/54 is bidirectional, whereas P6KE300A is unidirectional and features a cathode band. Substituting them without circuit review risks failure: the unidirectional part blocks reverse current but conducts only in one direction, while the CA version clamps symmetrically. Using P6KE300CA-E3/54 in place of P6KE300A on a DC-biased line may cause unintended conduction. Always verify polarity requirements and transient directionality before interchanging P6KE300A and P6KE300CA-E3/54.
