Product details
Overview
P6KE43CHE3/54 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 to 45.2 V breakdown voltage at 1 mA, 36.8 V stand-off voltage, 10.1 A peak pulse current, and 59.3 V maximum clamping voltage - deployed in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the P6KE43CHE3/54 datasheet, P6KE43CHE3/54 pinout, P6KE43CHE3/54 application, or P6KE43CHE3/54 equivalent, key selection criteria include bi-directional surge clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B for telecom and automotive transient protection systems.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical bi-directional conduction - no polarity marking required. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01 % duty cycle.
Designed for use without series impedance in many cases, it delivers 59.3 V clamping at 10.1 A while maintaining <1.0 μA reverse leakage at 36.8 V. The AEC-Q101 qualification confirms suitability for automotive environments with operating junction temperature up to +175 °C and storage down to –55 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 40.9 V to 45.2 V at 1 mA - defines reliable turn-on threshold for transient suppression across production lot |
| VWM | 36.8 V - maximum continuous working voltage before leakage exceeds 1.0 μA; sets safe operating margin below clamping |
| VC @ IPPM | 59.3 V at 10.1 A - peak clamped voltage during 600 W transient; determines protected circuit's maximum overvoltage stress |
| PPPM | 600 W (10/1000 μs waveform) - quantifies single-pulse energy handling capacity for lightning or ESD-like events |
| TJ max | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments without derating |
| RθJL | 20 °C/W - indicates efficient heat transfer from junction to lead; supports sustained surge handling with minimal PCB copper |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JESD22 |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. No polarity marking - bi-directional symmetry confirmed by identical electrical characteristics in both directions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient shunt path | Either end connects to protected line; no orientation dependency - simplifies layout and eliminates assembly errors |
| Case (body) | Non-electrical mechanical interface | Provides mechanical anchoring and thermal path via leadframe; no internal connection to semiconductor die |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable VBR tolerance across temperature and life cycle |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity without external series impedance in many designs |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces |
| UL 497B recognized (QVGQ2) | Meets safety requirements for telecom and industrial signal line protectors - reduces certification effort |
| RoHS-compliant HE3 suffix | Confirms AEC-Q101 qualification and JESD201 Class 2 whisker resistance - suitable for high-reliability automotive PCBs |
Applications

Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bi-directional shunt clamp placed directly across differential or single-ended signal lines upstream of IC input pins. Use Value: Limits transient voltage to ≤59.3 V during 10.1 A surges, preventing latch-up or gate oxide damage in downstream ASICs and microcontrollers. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring induced surges and ground bounce. IC Role / Device Role / Timing Role: Standoff voltage (36.8 V) ensures no conduction during normal operation; clamps within nanoseconds when transients exceed VBR. Use Value: Maintains system uptime by absorbing 600 W pulses without degradation - verified over 1000+ surge cycles per AEC-Q101 test plan. |
| Telecom Line Interface | Consumer Appliance Motor Control |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43CA | Same VBR range (40.9–45.2 V) and PPPM, but in smaller SMB (DO-214AA) package; RθJA = 40 °C/W vs. 75 °C/W for P6KE43CHE3/54 | Preferred where board space is constrained and thermal management uses larger copper areas or heatsinking | Select SMBJ43CA when footprint reduction outweighs lead-to-lead thermal performance trade-off |
| 1.5KE43CA | Higher PPPM = 1500 W, same DO-204AC package; VC = 69.4 V at 21.7 A - less precise clamping for lower-energy threats | Better suited for primary-level AC line or high-energy DC bus protection where tighter clamping is secondary to energy absorption | Choose 1.5KE43CA only if system-level testing confirms 69.4 V clamping is acceptable for protected ICs |
Compared with SMBJ43CA and 1.5KE43CA, P6KE43CHE3/54 offers optimal balance of clamping precision (59.3 V), AEC-Q101 qualification, and DO-15 manufacturability - making it preferred for cost-sensitive automotive and industrial signal-line protection where consistent low-VC is critical.

FAQ
What does the 'HE3' suffix indicate in P6KE43CHE3/54?
The HE3 suffix in P6KE43CHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. This distinguishes it from the commercial-grade E3 variant and confirms suitability for automotive applications requiring extended temperature operation and long-term reliability validation.
Is P6KE43CHE3/54 bi-directional or uni-directional?
P6KE43CHE3/54 is a bi-directional TVS diode, as confirmed by the 'CA' designation in its full family name (P6KE43CA) and absence of cathode band marking. Its electrical characteristics - including symmetric VBR, VWM, and VC - apply identically in both directions, enabling placement without orientation constraints.
What is the maximum clamping voltage of P6KE43CHE3/54 under surge conditions?
The maximum clamping voltage of P6KE43CHE3/54 is 59.3 V, measured at 10.1 A peak pulse current using the standard 10/1000 μs waveform. This value represents the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range.
Can P6KE43CHE3/54 replace P6KE43A in an existing design?
No - P6KE43CHE3/54 is bi-directional (P6KE43CA), whereas P6KE43A is uni-directional. Substituting them requires verifying that the circuit does not rely on DC blocking or polarity-sensitive conduction. Clamping behavior differs: P6KE43A clamps only in reverse bias, while P6KE43CHE3/54 clamps symmetrically in both polarities.
What is the thermal resistance from junction to lead (RθJL) for P6KE43CHE3/54?
The thermal resistance from junction to lead (RθJL) for P6KE43CHE3/54 is 20 °C/W, as specified in the Vishay datasheet. This parameter enables accurate thermal modeling when mounting on PCBs with limited copper area, confirming that short-duration surges will not exceed the +175 °C maximum junction temperature under typical lead termination conditions.
