Product details
Overview
P6KE43A-E3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 43 V breakdown voltage (VBR = 40.9–45.2 V at 1 mA), 36.8 V stand-off voltage (VWM), 59.3 V maximum clamping voltage (VC) at 10.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6KE43A-E3/54 datasheet, P6KE43A-E3/54 pinout, P6KE43A-E3/54 application, or P6KE43A-E3/54 equivalent, this device serves as a cost-optimized, AEC-Q101-qualified unidirectional TVS for board-level surge immunity where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.33), and DO-15 package compatibility are critical selection criteria.
Technical Context
The P6KE43A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, optimized for clamping transients induced by inductive switching or ESD events. Its unidirectional polarity uses a cathode band marking, and it delivers stable clamping performance across -55 °C to +175 °C junction temperature range.
It exhibits 0.101 %/°C temperature coefficient of VBR, 20 °C/W junction-to-lead thermal resistance, and 1.0 µA max reverse leakage at VWM. The device is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine) and supports soldering per JESD 22-B106 (275 °C, 10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 40.9 V / 45.2 V at 1.0 mA - defines reliable avalanche initiation threshold under DC bias |
| VWM | 36.8 V - maximum continuous working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 59.3 V at 10.1 A - clamped voltage during 600 W transient, limiting downstream stress |
| PPPM | 600 W (10/1000 µs) - surge energy handling capacity without degradation |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| RθJL | 20 °C/W - supports thermal design with PCB copper pour or short lead paths |
| Package | DO-15 (DO-204AC) - industry-standard axial-leaded through-hole package, RoHS-compliant (E3 suffix) |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; cathode indicated by color band on one end. Leads conform to J-STD-002 and JESD 22-B102 solderability standards. E3 suffix meets JESD 201 Class 1A whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Avalanche clamping terminal | Connected to protected line (e.g., 36 V rail); conducts when transient exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable long-term reliability and low parameter drift under thermal cycling |
| 600 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) without failure |
| Fast response time (<1 ns) | Clamps transients before sensitive ICs (e.g., CAN transceivers, microcontrollers) experience overstress |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD |
| Low incremental surge resistance | Minimizes VC overshoot during high-di/dt events, improving clamping precision |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting 5–36 V analog sensor outputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in engine control modules. IC Role / Device Role / Timing Role: Primary clamping element placed between sensor output and MCU ADC input, operating in standby until transient exceeds VWM. Use Value: Limits voltage seen by downstream op-amp or ADC to ≤59.3 V, preventing latch-up or gate oxide damage during 100 V/100 ms load dump events. | Use Scenario: Safeguarding 24 V digital input channels on programmable logic controllers against field-wiring surges and relay coil flyback. IC Role / Device Role / Timing Role: Unidirectional shunt protector mounted directly at connector entry point, with cathode tied to 24 V rail. Use Value: Clamps 1 kV/40 Ω surge (IEC 61000-4-5) to <60 V within nanoseconds, preserving optocoupler input integrity and enabling >100,000 surge cycles. |
| DC Power Rail Protection | Consumer Power Adapter Output |
Use Scenario: Secondary-side overvoltage suppression on 36 V DC power supplies feeding motor drivers or LED arrays. IC Role / Device Role / Timing Role: Standoff-rated TVS placed across output capacitor, conducting only during fault conditions exceeding 36.8 V. Use Value: Prevents catastrophic failure of downstream MOSFETs or electrolytic capacitors during regulator fault or feedback loop loss. | Use Scenario: Output-stage transient suppression in wall-mounted AC/DC adapters supplying USB-C PD or smart home hubs. IC Role / Device Role / Timing Role: Cost-optimized unidirectional clamp on +5 V or +12 V output, sized for UL 1449 Type 4 compliance. Use Value: Meets EN 61000-4-5 Level 3 (2 kV) immunity with minimal BOM cost increase and no PCB layout redesign. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43A | Same VBR range (40.9–45.2 V), but SMC (DO-214AB) surface-mount package; 600 W rating retained | Requires rework for SMT assembly; lacks axial-leaded mechanical robustness for high-vibration environments | Select SMBJ43A only when board space constraints prohibit through-hole mounting or automated pick-and-place is required. |
| 1.5KE43A | Same DO-15 package and electrical specs, but 1.5 kW peak power rating (10/1000 µs); higher IPPM (23.3 A) | Over-spec'd for most 600 W use cases; larger junction capacitance may affect high-speed signal lines | Choose 1.5KE43A only when legacy designs require backward-compatible footprint with headroom for future surge margin increases. |
Compared with SMBJ43A and 1.5KE43A, P6KE43A-E3/54 offers optimal balance of proven axial-leaded reliability, AEC-Q101 qualification, and precise 600 W surge handling - making it preferred for cost-sensitive, vibration-prone, or serviceable through-hole applications where exact power rating alignment matters.

FAQ
What is the breakdown voltage tolerance of P6KE43A-E3/54?
The P6KE43A-E3/54 has a specified breakdown voltage range of 40.9 V to 45.2 V at 1.0 mA test current, representing ±5% tolerance around the nominal 43 V rating. This ensures consistent clamping behavior across production lots while allowing margin for temperature drift (0.101 %/°C) and aging effects in long-life deployments.
Is P6KE43A-E3/54 suitable for automotive applications?
Yes, the P6KE43A-E3/54 is AEC-Q101 qualified per its HE3 suffix variant; however, the E3/54 version is RoHS-compliant commercial grade. For automotive use, specify P6KE43AHE3/54. Both share identical electrical specs, but only the HE3 suffix undergoes full AEC-Q101 stress testing including temperature cycling and HTRB.
What is the maximum clamping voltage of P6KE43A-E3/54 under surge conditions?
The maximum clamping voltage of P6KE43A-E3/54 is 59.3 V at 10.1 A peak pulse current (10/1000 µs waveform). This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range (-55 °C to +175 °C).
Can P6KE43A-E3/54 be used in bidirectional configurations?
No, P6KE43A-E3/54 is unidirectional only. Bidirectional variants use the "CA" suffix (e.g., P6KE43CA). Using P6KE43A-E3/54 in AC-coupled or symmetrical surge environments would result in forward conduction during negative half-cycles, potentially causing failure. Always match polarity to system grounding architecture.
What packaging format does P6KE43A-E3/54 ship in?
P6KE43A-E3/54 ships in 13-inch diameter paper tape and reel format, with 4000 units per reel (package code "54"). The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance. Lead finish is matte tin, solderable per J-STD-002 and JESD 22-B102 standards.
