Product details
Overview
P6KE33CA A0G from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 33 V, clamps transients to ≤47.7 V at 13.0 A peak surge current, and operates with ≤1 μA leakage above 28.2 V standoff voltage - deployed in automotive lighting control modules and industrial sensor interfaces.
For engineers reviewing the P6KE33CA A0G datasheet, P6KE33CA A0G pinout, P6KE33CA A0G application, or P6KE33CA A0G equivalent, key selection criteria include bidirectional clamping capability, DO-15 package compatibility, AEC-Q101 qualification status, and 10/1000 µs surge rating - critical for ESD and load-dump immunity in harsh-environment electronics.
Technical Context
The P6KE33CA A0G implements a silicon avalanche diode structure optimized for fast transient response (<5.0 ns rise time from 0 V to VBR) and low dynamic impedance. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating circuits without polarity sensitivity.
It delivers 600 W non-repetitive peak pulse power per 10/1000 µs waveform, with thermal derating above 25 °C ambient and junction temperature limits up to +175 °C - supporting operation in under-hood automotive and industrial power supply environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 29.7 V / 36.3 V at 1 mA test current - defines reliable avalanche initiation window for consistent clamping onset |
| VWM | 26.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPP | 13.0 A at 10/1000 µs - peak surge current it safely shunts without failure |
| VC @ IPP | 47.7 V - maximum clamped voltage seen by protected circuit during rated surge |
| IR @ VWM | ≤1 µA - ensures minimal standby power loss and signal integrity in high-impedance nodes |
| TJ max | +175 °C - enables use in high-temperature locations such as engine control units and motor drives |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400 g mass and UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded plastic case with cathode band marking for unidirectional variants; P6KE33CA A0G is bidirectional and marked with part-specific code (no polarity band required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on transient polarity - no orientation required during PCB placement |
| Lead 1 / Lead 2 | Current conduction path | Leads are pure tin-plated, solderable per J-STD-002, and support 100 A surge (unidirectional only) - mechanical connection points for PCB mounting |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signals and floating buses without external polarity management circuitry |
| 600 W 10/1000 µs surge rating | Withstands automotive load-dump and ISO 7637-2 Pulse 5a events without degradation |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and lighting systems |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes voltage overshoot during transients - critical for protecting 3.3 V/5 V logic interfaces |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and environmental directives for global manufacturing and end-of-life handling |
Applications
| Automotive LED Headlamp Driver | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protects LED driver ICs from load-dump transients (>120 V, 400 ms) during vehicle battery disconnection. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed across input rail upstream of DC/DC controller. Use Value: Limits rail voltage to ≤47.7 V during surge, preventing latch-up or gate oxide damage in downstream MOSFET drivers. |

Use Scenario: Guards AC/DC converter front-end against lightning-induced surges on utility mains input. IC Role / Device Role / Timing Role: First-line protection device placed after fuse and before bridge rectifier. Use Value: Absorbs 600 W pulses without failure, enabling compliance with IEC 61000-4-5 Level 3 (2 kV line-earth) |
Use Scenario: Protects 24 V digital input channels from inductive kickback when solenoids or relays de-energize. IC Role / Device Role / Timing Role: Parallel-connected TVS across input terminals to clamp reverse EMF spikes. Use Value: Limits spike amplitude to 47.7 V within 5 ns, preventing false triggering or latch-up in optocoupler input stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | 600 W rating, SMB package (surface-mount), lower IPP (12.3 A), VC = 53.3 V | Requires PCB rework for SMT layout; better suited for space-constrained designs | Select when board area is limited and automated assembly is preferred over through-hole |
| 1.5KE33CA | 600 W rating, DO-201AD package, higher VC (53.3 V), slower response (~10 ns) | Larger footprint than DO-15; not AEC-Q101 qualified | Choose for cost-sensitive industrial applications where automotive qualification is unnecessary |
Compared with SMBJ33CA and 1.5KE33CA, the P6KE33CA A0G offers AEC-Q101 qualification, tighter VC (47.7 V), and DO-15 compatibility - making it optimal for automotive and legacy through-hole designs requiring proven reliability and direct replacement capability.

FAQ
What is the clamping voltage of P6KE33CA A0G at its rated surge current?
The P6KE33CA A0G clamps to a maximum of 47.7 V when subjected to its rated 13.0 A peak pulse current (10/1000 µs waveform). This value is measured across the device terminals during standardized surge testing and defines the upper voltage limit imposed on protected circuitry - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
Is P6KE33CA A0G AEC-Q101 qualified?
Yes, P6KE33CA A0G is AEC-Q101 qualified. The "H" suffix denotes AEC-Q101 qualification per the ordering code table, and the "A0G" variant retains this qualification. This certification confirms its suitability for automotive applications including engine control, body electronics, and lighting systems where reliability under thermal cycling, humidity, and mechanical stress is mandatory.
What does the "CA" suffix indicate in P6KE33CA A0G?
The "CA" suffix in P6KE33CA A0G specifies bidirectional configuration - meaning the device provides symmetrical clamping for both positive and negative transients without polarity dependence. Unlike "A"-suffixed unidirectional variants, P6KE33CA A0G has no cathode band marking and may be installed in either orientation on the PCB.
What is the standoff voltage (VWM) of P6KE33CA A0G?
The standoff voltage VWM of P6KE33CA A0G is 26.8 V - the maximum DC or continuous reverse voltage that can be applied without exceeding 1 µA leakage current. This value ensures compatibility with 24 V nominal systems while providing sufficient margin above normal operating voltage to avoid false triggering during ripple or tolerance drift.
Which package type does P6KE33CA A0G use?
P6KE33CA A0G uses the DO-204AC (commonly known as DO-15) package: an axial-leaded, epoxy-molded case with 0.400 g mass, UL 94V-0 flammability rating, and pure tin-plated leads compliant with J-STD-002 solderability requirements - optimized for through-hole mounting in high-reliability industrial and automotive assemblies.
