Product details
Overview
P6KE43C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 40.9 V minimum and 45.2 V maximum breakdown voltage at 1.0 mA test current, and clamps to ≤59.3 V at 10.1 A peak pulse current. It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems against ESD and inductive switching surges.
For engineers reviewing the P6KE43C-E3/54 datasheet, P6KE43C-E3/54 pinout, P6KE43C-E3/54 application, or P6KE43C-E3/54 equivalent, key selection criteria include bi-directional clamping capability, 59.3 V max clamping voltage at 10.1 A, -55 °C to +175 °C operating junction temperature, RoHS-compliant matte tin-plated leads, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE43C-E3/54 operates as a voltage-clamped surge protector with symmetrical bi-directional avalanche breakdown behavior - no polarity marking required. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients induced by relay switching or lightning-induced coupling.
It delivers 600 W peak pulse power under standardized 10/1000 μs waveform conditions with 0.01 % duty cycle, and derates linearly above 25 °C ambient per Fig. 2. Thermal resistance is 20 °C/W junction-to-lead, enabling effective heat dissipation into PCB copper when mounted with ≥0.375" lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 40.9 V min / 45.2 V max at 1.0 mA - defines precise voltage threshold where avalanche conduction begins in both directions |
| Stand-off Voltage (VWM) | 36.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA; ensures no false triggering during normal operation |
| Max Clamping Voltage (VC) | 59.3 V at 10.1 A IPPM - actual worst-case voltage seen by protected circuit during 10/1000 μs transient, directly limiting stress on downstream components |
| Peak Pulse Power (PPPM) | 600 W - sustained energy-handling capacity under standard surge waveform; enables protection against IEC 61000-4-5 Level 3/4 surges |
| Junction Temperature Range | -55 °C to +175 °C - supports operation in under-hood automotive and high-temperature industrial environments without derating |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with UL 94 V-0 molded epoxy, compatible with wave soldering (275 °C, 10 s) |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass passivated chip in molded epoxy housing. Matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards. Bi-directional construction means no cathode marking; both terminals are functionally identical.

IC Role / Device Role / Timing Role: First-stage clamping device placed between bridge output and bulk capacitor, absorbing line-to-line and line-to-ground transients. Use Value: 36.8 V stand-off voltage avoids conduction during 30 V peak rectified mains, while 59.3 V clamping prevents overvoltage stress on 65 V-rated MOSFETs and controllers. |
Use Scenario: Protecting Ethernet PHYs and DSL line drivers from induced surges on twisted-pair telecom/data lines exposed to outdoor wiring. IC Role / Device Role / Timing Role: Bi-directional TVS deployed across differential pairs (e.g., TX+/TX−) to suppress common-mode and differential-mode transients. Use Value: Symmetric clamping ensures equal protection regardless of surge polarity; low capacitance (<50 pF typical) preserves signal integrity up to 100 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43CA | Same 43 V nominal breakdown, but SMB package (surface-mount); 600 W rating, lower thermal resistance (junction-to-PCB ≈ 15 °C/W) | Better suited for space-constrained PCBs; requires reflow soldering instead of wave/through-hole | Select SMBJ43CA when board real estate is limited and automated SMT assembly is used. |
| 1.5KE43CA | Same DO-204AC package and 43 V rating, but higher 1500 W peak pulse power; larger die size increases capacitance and thermal mass | Over-specified for most 600 W use cases; may cause unnecessary cost and board area usage | Choose 1.5KE43CA only if system-level surge testing requires >600 W margin or legacy design reuse mandates identical footprint. |
Compared with SMBJ43CA and 1.5KE43CA, the P6KE43C-E3/54 offers optimal balance of through-hole manufacturability, AEC-Q101 qualification, and precise 600 W surge handling - making it ideal for automotive and industrial designs requiring proven reliability without over-engineering.

FAQ
What does the 'C' suffix indicate in P6KE43C-E3/54?
The 'C' in P6KE43C-E3/54 denotes bi-directional configuration - meaning the device provides symmetrical transient suppression in both polarities without cathode marking. This distinguishes it from uni-directional variants like P6KE43A-E3/54, which require correct orientation relative to circuit ground. The P6KE43C-E3/54 is specified for use in AC-coupled or floating signal paths where voltage transients can occur with either polarity.
Is P6KE43C-E3/54 qualified for automotive applications?
Yes, P6KE43C-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including engine control, body electronics, and ADAS sensor interfaces. The qualification covers stress tests for temperature cycling, humidity, mechanical shock, and surge endurance - validating reliability under harsh vehicle operating conditions. This makes P6KE43C-E3/54 appropriate for deployment in production vehicles where component failure could impact safety or functionality.
What is the maximum clamping voltage of P6KE43C-E3/54 and under what test condition?
The maximum clamping voltage of P6KE43C-E3/54 is 59.3 V, measured at 10.1 A peak pulse current using the standardized 10/1000 μs double-exponential waveform. This value represents the worst-case voltage imposed on the protected circuit during a surge event and is guaranteed across the full operating temperature range. Designers use this parameter to verify that downstream components - such as 3.3 V or 5 V logic ICs - remain within absolute maximum ratings during transient exposure.
How does the E3/54 suffix affect packaging and compliance of P6KE43C-E3/54?
The E3/54 suffix indicates RoHS-compliant matte tin-plated leads (E3) and packaging in 13-inch paper tape and reel with 4000 units per reel (54). The E3 designation confirms compliance with JESD 201 Class 1A whisker testing, ensuring long-term solder joint integrity in high-reliability applications. The 54 package code specifies industry-standard reel dimensions and orientation, facilitating compatibility with automated pick-and-place and wave soldering equipment used in high-volume manufacturing of P6KE43C-E3/54.
Can P6KE43C-E3/54 be used in place of P6KE43A-E3/54?
No, P6KE43C-E3/54 cannot be used as a direct replacement for P6KE43A-E3/54 without circuit review, because the former is bi-directional while the latter is uni-directional with defined cathode polarity. Substituting P6KE43C-E3/54 in a uni-directional design may result in unintended conduction during normal forward bias or failure to clamp correctly in DC-biased paths. Always verify layout, grounding scheme, and signal polarity before interchanging P6KE43C-E3/54 and P6KE43A-E3/54 in an existing design.
