Product details
Overview
P6KE13CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in power supply input stages and automotive ECU protection circuits. It features a 13V nominal breakdown voltage (VBR min/max: 11.7V–14.3V), 10.5V stand-off voltage (VWM), 19.0V maximum clamping voltage at 33A peak surge current, and operates across –55°C to +175°C junction temperature range.
For engineers reviewing the P6KE13CH datasheet, P6KE13CH pinout, P6KE13CH application, or P6KE13CH equivalent, this page delivers verified electrical parameters, DO-204AC package details, AEC-Q101 qualification status, clamping performance under 10/1000μs transients, and direct alternatives for automotive-grade surge protection design.
Technical Context
The P6KE13CH implements a silicon avalanche diode structure optimized for fast transient response (<1.0ps rise time from 0V to VBR) and low dynamic impedance. Its unidirectional configuration enables asymmetric clamping-blocking reverse conduction while clamping positive surges above VWM.
It meets ANSI/IEEE C62.35 standards for surge immunity testing and supports 600W non-repetitive peak pulse power at 10/1000μs waveform, with thermal derating above 25°C ambient per published curve (Fig.2). The device is rated for 100A forward surge current (IFSM, 8.3ms half-sine) and exhibits <1μA reverse leakage at 10.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 11.7V–14.3V at 1mA test current - defines reliable avalanche onset window for consistent clamping threshold |
| VWM | 10.5V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPP | 19.0V at 33A - clamping voltage during 10/1000μs surge; determines protected circuit's maximum transient exposure |
| PPK | 600W - peak pulse power handling capability under standardized surge waveform |
| TJ max | +175°C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| IR @ VWM | <1μA - ensures minimal standby power loss and signal integrity in high-impedance sensing paths |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400g 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 polarity. Leads are pure tin-plated, solderable per J-STD-002, and pass JESD 201 Class 2 whisker testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / surge return node | Connected to system ground or low-side reference; carries full surge current during clamping |
| Cathode | Clamping output / protected line connection | Connected to line being protected (e.g., 12V rail); conducts when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including temperature cycling, HTRB, and ESD |
| 600W 10/1000μs surge rating | Withstands high-energy transients common in load-dump and ISO 7637-2 Pulse 5a scenarios |
| Fast response time <1.0ps | Clamps before sensitive downstream ICs experience damaging overvoltage |
| Low dynamic impedance | Ensures stable clamping voltage across wide current range (1A–33A), minimizing overshoot |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and environmental directives for global automotive and industrial use |
Applications
| Automotive Power Input Protection | Industrial DC Power Rail Clamping |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to ISO 7637-2 load dump pulses up to 120V. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power rail, placed upstream of DC-DC converters and microcontrollers. Use Value: Limits rail voltage to ≤19.0V during 33A surge events, preventing latch-up or gate oxide damage in downstream logic. | Use Scenario: 24V PLC I/O modules subjected to inductive switching spikes from solenoid drivers. IC Role / Device Role / Timing Role: Transient suppression at terminal block entry point, shunting energy before it reaches isolation barriers. Use Value: Absorbs 600W surges without degradation, maintaining VWM = 10.5V to avoid false triggering during normal operation. |
| Lighting System Surge Suppression | ESD-Prone Sensor Interface Protection |
Use Scenario: LED driver inputs in commercial lighting fixtures experiencing lightning-induced surges on AC mains. IC Role / Device Role / Timing Role: First-line defense on rectified DC bus, coordinated with MOVs for multi-stage protection. Use Value: Fast <1.0ps response captures early transient edge, reducing stress on secondary TVS arrays and bridge rectifiers. | Use Scenario: CAN/LIN transceiver lines in vehicle body control modules subject to ±8kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Secondary-level clamping after series impedance, limiting voltage seen by transceiver pins. Use Value: Low leakage (<1μA) avoids signal distortion on high-impedance data lines while clamping to 19.0V during ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Surface-mount SMB package (vs. axial DO-15); 600W rating; bidirectional variant available | Better suited for automated SMT assembly; lower profile but requires PCB real estate vs. through-hole mounting | Select SMBJ13A when board space is constrained and reflow compatibility is required |
| 1.5KE13A | Same DO-204AC package; higher 1.5kW peak power rating; slower response (~1ns vs. <1ps) | Used where higher single-event energy absorption is needed, e.g., telecom power entry | Choose 1.5KE13A only if 1.5kW surge margin is mandatory and sub-nanosecond response is not critical |
Compared with SMBJ13A and 1.5KE13A, the P6KE13CH offers AEC-Q101 qualification and superior speed for automotive environments, while retaining through-hole reliability and thermal mass advantages of DO-15 packaging-making it optimal for under-hood power modules requiring both robustness and fast clamping.

FAQ
What is the key difference between P6KE13CH and P6KE13A?
The P6KE13CH is AEC-Q101 qualified and marked with "H" suffix per TSC ordering code, indicating automotive-grade reliability validation. In contrast, P6KE13A lacks AEC-Q101 certification and is intended for industrial/commercial use only. Both share identical electrical specs (VBR: 12.4V–13.7V, VC: 18.2V), but P6KE13CH undergoes extended stress testing including temperature cycling and HTRB. For automotive applications, P6KE13CH is the required variant.
Does P6KE13CH support bidirectional transient suppression?
No, P6KE13CH is a unidirectional TVS diode, indicated by its "CH" suffix and cathode band marking. It clamps only positive transients relative to ground. Bidirectional variants (e.g., P6KE13C) exist in the same series but have different internal construction and marking. Using P6KE13CH for bidirectional protection would leave negative-going transients unclamped and potentially damage downstream components.
What is the maximum allowable ambient temperature for continuous operation of P6KE13CH?
P6KE13CH has a junction temperature limit of +175°C, but its steady-state power dissipation (PD) is derated above 25°C ambient. At TA = 75°C, maximum continuous power is 5W with 9.5mm lead lengths mounted on 5×5 mm copper pads. For reliable long-term operation, ambient temperature should be kept below 85°C in enclosed enclosures, with thermal modeling confirming TJ remains within spec under worst-case surge duty cycles.
How does the 10/1000μs waveform relate to real-world transients like ISO 7637-2 Pulse 5a?
The 10/1000μs surge waveform is the standardized test condition used to rate P6KE13CH's 600W peak power capability. ISO 7637-2 Pulse 5a (load dump) approximates this shape-10μs rise time, ~1000μs decay-making P6KE13CH directly applicable for that automotive stress test. Its 19.0V clamping voltage at 33A ensures protected circuits see less than 20V during such events, satisfying typical 24V system immunity requirements.
Is P6KE13CH compatible with lead-free reflow soldering processes?
P6KE13CH uses pure tin-plated leads compliant with J-STD-002 for solderability, but it is an axial-leaded through-hole component-not designed for reflow. It is intended for wave soldering or hand soldering. For lead-free assembly, peak temperatures must not exceed 260°C for ≤10 seconds per IPC-J-STD-001, and thermal shock from rapid heating must be avoided to prevent molding compound delamination. Reflow is not recommended.
