Product details
Overview
P6KE30CA 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 30 V, clamps transients to ≤41.4 V at 15 A peak surge current, and delivers sub-nanosecond response time (<5 ns) for ESD and EFT immunity. It is commonly deployed in automotive body control modules and industrial I/O interfaces requiring AEC-Q101-qualified surge resilience.
For engineers reviewing the P6KE30CA datasheet, P6KE30CA pinout, P6KE30CA application, or P6KE30CA equivalent, key selection criteria include its bidirectional DO-15 package, 25.6 V standoff voltage, <1 μA leakage above 10 V, and compatibility with 10/1000 μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE30CA operates as a silicon avalanche diode configured in bidirectional (symmetrical) mode, enabling identical clamping behavior in both polarities. Its junction structure supports unidirectional or bidirectional operation depending on suffix (C = unidirectional, CA = bidirectional), with thermal derating up to 175°C junction temperature and compliance with ANSI/IEEE C62.35 surge standards.
It exhibits low dynamic impedance and fast turn-on-typically under 5 ns from 0 V to VBR-due to optimized avalanche multiplication physics. The device meets UL 94V-0 flammability requirements and JESD201 Class 2 whisker resistance, confirming suitability for high-reliability PCB assemblies subject to thermal cycling and long-term solder joint integrity demands.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W at 10/1000 μs waveform - sustains single high-energy surges without failure |
| Standoff Voltage VWM | 25.6 V - maximum continuous reverse voltage before significant leakage begins |
| Breakdown Voltage VBR | 28.5–31.5 V at 1 mA test current - defines precise avalanche initiation threshold |
| Clamping Voltage VC | 41.4 V at 15 A peak current - limits downstream circuit voltage during surge events |
| Leakage Current ID | <1 μA at 25.6 V - ensures minimal power loss and signal integrity in standby |
| Response Time | <5 ns (bidirectional) - enables effective suppression of ESD and fast EFT transients |
| Junction Temperature | −55°C to +175°C - supports operation in under-hood automotive and industrial environments |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking for unidirectional variants; P6KE30CA uses symmetrical bidirectional construction with no polarity marking required beyond standard cathode band (functionally non-directional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (reversible) | Bidirectional avalanche junction terminals | Either lead may serve as anode or cathode - identical clamping in both directions |
| Case / Body | Non-electrical mechanical interface | No internal connection; serves only as thermal mass and mounting anchor |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including temperature cycling, HTRB, and ESD |
| Low clamping ratio (VC/VBR) | 1.30–1.45 - minimizes overvoltage margin needed for protected ICs' absolute maximum ratings |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU Directive 2011/65/EU - supports green manufacturing and end-of-life compliance |
| UL Recognized | File #E-326243 - confirms safety compliance for use in certified end equipment |
| High surge current rating | 15 A peak (10/1000 μs) - withstands repetitive load dump and inductive switching events |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protects microcontroller GPIO and CAN transceiver power rails from load dump and jump-start transients. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to clamp ±100 V spikes before reaching LDOs and logic. Use Value: Enables compliance with ISO 7637-2 Pulse 5a (load dump) by limiting rail voltage to ≤41.4 V during 60 V, 100 ms surges. |
Use Scenario: Shields 24 V digital input circuits from field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Primary front-end protection element across input terminals, upstream of optocoupler or Schmitt trigger. Use Value: Prevents false triggering and latch-up in industrial controllers by suppressing >1 kV EFT bursts per IEC 61000-4-4. |
| LED Driver Power Supply | RS-485 Communication Port |
Use Scenario: Guards constant-current LED driver ICs against inrush and lightning-induced surges on 12–48 V DC bus. IC Role / Device Role / Timing Role: Parallel-connected TVS across input capacitor to absorb energy before it reaches PWM controller and MOSFET gate drivers. Use Value: Extends MTBF by eliminating catastrophic failure modes caused by 600 W transient energy exceeding IC SOA limits. |
Use Scenario: Safeguards RS-485 transceivers (e.g., SN65HVD230) from ground potential differences and cable discharge events. IC Role / Device Role / Timing Role: Differential-mode TVS across A/B lines and common-mode TVS from A/B to GND - P6KE30CA used in common-mode configuration. Use Value: Maintains data integrity during 8 kV contact ESD per IEC 61000-4-2 by clamping transients within transceiver's ±12 V common-mode range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ30CA | Same DO-214AC (SMA) package; 30 V VBR min/max tighter (28.5–31.5 V); 600 W rating; slightly higher VC (48.4 V @ 12.3 A) | Higher clamping voltage reduces margin for 3.3 V/5 V logic protection; better suited for 24 V+ systems | Select SMAJ30CA when board space allows SMA footprint and system VIN exceeds 36 V. |
| Vishay 1.5KE30CA | Same DO-204AC (DO-15) package; identical VBR (28.5–31.5 V); same 600 W rating; lower VC (40.5 V @ 14.8 A); AEC-Q101 not specified | Lower clamping improves protection margin but lacks automotive qualification documentation | Choose 1.5KE30CA for cost-sensitive industrial designs where AEC-Q101 is not mandated. |
Compared with SMAJ30CA and 1.5KE30CA, the P6KE30CA offers AEC-Q101 validation in the legacy DO-15 form factor with balanced clamping performance-making it optimal for automotive retrofit modules and legacy industrial boards constrained by axial lead spacing.

FAQ
What does the 'CA' suffix indicate in P6KE30CA?
The 'CA' suffix in P6KE30CA denotes bidirectional configuration-meaning the device provides symmetrical clamping for both positive and negative transients without polarity sensitivity. Unlike unidirectional 'C' variants, P6KE30CA has no designated anode or cathode and functions identically regardless of voltage polarity applied across its terminals.
Is P6KE30CA suitable for protecting 3.3 V logic circuits?
No, P6KE30CA is not appropriate for direct protection of 3.3 V logic circuits because its 25.6 V standoff voltage exceeds typical I/O absolute maximum ratings. It is intended for higher-voltage rails such as 24 V industrial inputs or 12–48 V LED drivers. For 3.3 V systems, lower-voltage TVS devices like P6KE6.8CA or SMAJ6.8CA are recommended.
Does P6KE30CA meet AEC-Q101 requirements?
Yes, P6KE30CA is explicitly AEC-Q101 qualified per the manufacturer's documentation. This includes passing stress tests for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge-confirming suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum peak surge current rating for P6KE30CA?
The maximum peak surge current (IPP) for P6KE30CA is 15 A under the standard 10/1000 μs double-exponential waveform. This value is derived from its 600 W peak pulse power rating and 41.4 V clamping voltage (IPP = PPK/VC), and is validated per Fig. 3 in the official P6KE series datasheet.
Can P6KE30CA be used in place of P6KE30A?
No-P6KE30A is unidirectional with a cathode band and asymmetric behavior, while P6KE30CA is bidirectional with no polarity marking. Substituting one for the other risks incorrect circuit protection: P6KE30A would fail to clamp negative transients, and P6KE30CA may misbehave in circuits relying on DC blocking or polarity-specific biasing.
