Product details
Overview
P4KE39CA A0G from Taiwan Semiconductor is a bidirectional 400W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a nominal breakdown voltage of 39V, clamps transients to ≤56.4V at 7.4A peak pulse current, and operates across –55°C to +175°C junction temperature range - deployed in automotive lighting control modules and industrial PLC I/O protection.
For engineers reviewing the P4KE39CA A0G datasheet, P4KE39CA A0G pinout, P4KE39CA A0G application, or P4KE39CA A0G equivalent, key selection criteria include its bidirectional DO-41 package, 31.6V working stand-off voltage, <1μA reverse leakage at VWM, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P4KE39CA A0G implements a silicon avalanche diode structure optimized for fast clamping response (<5ns for bidirectional operation) and low dynamic impedance under 10/1000μs surge waveforms. Its bidirectional symmetry ensures identical electrical characteristics in both polarities, eliminating polarity-sensitive layout constraints.
It meets ANSI/IEEE C62.35 standards for transient suppression, with a maximum clamping voltage of 56.4V at 7.4A IPPM and a temperature coefficient of 0.100%/°C for VBR - enabling stable performance across wide thermal operating ranges without external compensation.

| ID @ VWM | <1 μA - Ultra-low reverse leakage ensures minimal standby power loss in always-on circuits |
| TJ max | +175 °C - Enables placement near heat-generating components in engine control units or motor drives |
| Package | DO-204AL (DO-41) - Industry-standard axial leaded package with UL 94V-0 molding compound |
Pinout & Package
DO-204AL (DO-41) axial-leaded package with cathode band marking for unidirectional variants; P4KE39CA A0G is bidirectional and has no polarity marking - terminals are functionally symmetric.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | DO-214AA package, 36V VWM, 58.1V VC @ 6.9A, 600W PPK | Higher power rating but larger footprint; requires PCB rework for DO-41-to-SMB transition | Select when higher surge margin is needed and board space permits SMC/SMB package |
| 1.5KE39CA | Same DO-41 package, 39V nominal, but 1500W PPK and 60V VC @ 25A - higher capacitance (150pF vs. ~50pF) | Overkill for 400W-class systems; may affect high-speed signal integrity due to higher junction capacitance | Prefer only where legacy 1.5KE footprint compatibility is mandatory and surge energy exceeds 400W |
Compared with SMBJ36CA and 1.5KE39CA, the P4KE39CA A0G delivers optimal balance of compact DO-41 form factor, AEC-Q101 qualification, and precise 400W/39V clamping - making it ideal for space-constrained automotive and industrial control designs requiring certified reliability without over-engineering.

FAQ
What does the 'CA' suffix indicate in P4KE39CA A0G?
The 'CA' suffix denotes bidirectional configuration - meaning the P4KE39CA A0G provides symmetrical avalanche clamping in both forward and reverse directions, unlike unidirectional 'A' or base variants. This eliminates polarity concerns during PCB placement and supports AC-coupled or floating signal line protection without external diode pairing.
Is P4KE39CA A0G suitable for IEC 61000-4-5 surge testing?
Yes, the P4KE39CA A0G is rated for 400W peak pulse power at 10/1000μs waveform per ANSI/IEEE C62.35, directly aligning with IEC 61000-4-5 open-circuit voltage test profiles. When mounted with recommended copper pad area (5×5 mm per lead), it reliably clamps 4kV surges to ≤56.4V - meeting Level 4 compliance for 24V industrial systems.
How does the A0G packaging differ from standard tape-and-reel options?
The 'A0G' suffix indicates ammo box packaging containing 3,000 units per box - optimized for manual assembly, prototyping, and low-volume production runs. Unlike tape-and-reel formats (e.g., P4KE39CA), A0G avoids carrier tape costs and enables rapid hand-soldering or selective placement without reel-handling equipment.
What is the maximum operating temperature for P4KE39CA A0G?
The P4KE39CA A0G has a specified junction temperature range of –55°C to +175°C, with derated power dissipation above 25°C ambient per Fig.2. At 100°C ambient, its steady-state power capability drops to ~0.5W (mounted on 5×5 mm copper pads), while transient surge capability remains fully rated up to TJ = 175°C.
Does P4KE39CA A0G require heatsinking for continuous operation?
No heatsink is required for transient suppression duty cycles, as the P4KE39CA A0G handles 400W non-repetitive pulses without thermal accumulation. For steady-state dissipation, its 1W rating at TL = 75°C assumes 9.5mm lead length and 5×5 mm copper pads - sufficient for most board-level thermal environments without added heatsinks.
