Product details
Overview
P4KE11C from Taiwan Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 11 V nominal breakdown voltage, 8.92 V working stand-off voltage, 16.2 V maximum clamping voltage at 26 A peak pulse current, and 400 W peak pulse power rating per 10/1000 µs waveform - deployed in automotive body control modules to safeguard CAN transceivers against load dump and EFT events.
For engineers reviewing the P4KE11C datasheet, P4KE11C pinout, P4KE11C application, or P4KE11C equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, leakage current below 1 µA at 8.92 V, unidirectional polarity marking, DO-41 package thermal derating above 25°C, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P4KE11C operates as a silicon avalanche diode with fast response time (<1.0 ps from 0 V to VBR) and low dynamic impedance, enabling effective suppression of sub-microsecond transients such as ESD and EFT. Its unidirectional configuration provides forward conduction path during overvoltage while blocking reverse current until breakdown threshold is exceeded.
Rated for 175°C maximum junction temperature and compliant with UL 94V-0 molding compound, the device supports operation across –55°C to +175°C ambient range. It meets ANSI/IEEE C62.35 surge waveform standards and delivers 26 A peak pulse current capability under 10/1000 µs test conditions without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.92 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC rail margin below clamping onset. |
| VBR @ IT=1 mA | 9.90–12.1 V - Breakdown voltage range at 1 mA test current; ensures consistent avalanche initiation across production lots. |
| VC @ IPPM=26 A | 16.2 V - Clamping voltage under 10/1000 µs surge; must remain below protected IC's absolute maximum input rating. |
| PPK | 400 W - Peak pulse power handling capacity; determines survivability against ISO 7637-2 Pulse 1/2a/5a waveforms. |
| IR @ VWM | <1 µA - Reverse leakage at stand-off voltage; minimizes quiescent power loss and avoids false triggering in high-impedance circuits. |
| TJMAX | 175°C - Maximum junction temperature; enables placement near heat-generating components with appropriate PCB copper area. |
| Package | DO-204AL (DO-41) - Axial-leaded through-hole package with tin-plated leads; compatible with wave soldering and manual rework. |
Pinout & Package
DO-204AL (DO-41) axial package with cathode band marking indicating the cathode terminal. Leads are pure tin-plated and solderable per J-STD-002; polarity is marked on body for unidirectional orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during positive surge when cathode is at higher potential. |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail or CAN_H); initiates breakdown when voltage exceeds VBR, shunting surge to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and infotainment power supplies requiring extended temperature cycling and humidity testing. |
| 400 W peak pulse power | Withstands ISO 7637-2 Load Dump (Pulse 5a) up to 60 V/100 ms and EFT bursts (IEC 61000-4-4) without parametric shift or failure. |
| <1.0 ps response time | Clamps transients before sensitive logic inputs reach destructive voltage thresholds - critical for protecting 3.3 V or 5 V microcontrollers. |
| UL 94V-0 flammability rating | Molding compound prevents flame propagation during fault conditions, satisfying end-equipment safety certifications like UL 60950-1. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; suitable for green manufacturing and export to regulated markets. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Surface-mount SMB package; 11.1 V VBR min; 17.0 V VC @ 23.5 A; 600 W PPK. | Requires PCB redesign for SMT layout; better suited for space-constrained designs with automated assembly. | Select SMBJ11A when board real estate is limited and reflow compatibility is required; verify thermal pad design for 175°C TJ. |
| 1N6267A | Same DO-41 package; 11.1 V VBR min; 17.0 V VC @ 23.5 A; 400 W PPK; no AEC-Q101 qualification. | Lacks automotive qualification; acceptable for industrial or consumer applications where qualification is not mandated. | Choose 1N6267A for cost-sensitive non-automotive use; confirm absence of AEC-Q101 testing if used in automotive Tier 2 subsystems. |
Compared with SMBJ11A and 1N6267A, the P4KE11C offers AEC-Q101 qualification in a through-hole DO-41 package with tighter VC (16.2 V) and lower leakage (<1 µA), making it optimal for automotive and high-reliability industrial designs where qualification and precise clamping are mandatory.

FAQ
What is the clamping voltage of P4KE11C and why does it matter?
The P4KE11C has a maximum clamping voltage (VC) of 16.2 V at 26 A peak pulse current under 10/1000 µs waveform. This value matters because it defines the highest voltage imposed on downstream circuitry during a surge event - ensuring protected ICs (e.g., 12 V-rated regulators or CAN transceivers) remain within their absolute maximum ratings. Exceeding this clamping level risks latch-up or permanent damage.
Is P4KE11C unidirectional or bidirectional, and how is polarity identified?
P4KE11C is a unidirectional TVS diode, indicated by the "C" suffix and cathode band marking on the DO-41 package body. The cathode terminal connects to the protected line (e.g., 12 V rail), while the anode connects to ground or return path. Bidirectional variants use "CA" suffix (e.g., P4KE11CA) and lack polarity marking.
Does P4KE11C meet automotive qualification standards?
Yes, P4KE11C is AEC-Q101 qualified, as confirmed in the manufacturer's documentation. This qualification covers stress tests including temperature cycling, humidity bias HAST, mechanical shock, and ESD - validating its suitability for under-hood and cabin automotive applications such as body control modules and lighting controllers.
What is the maximum junction temperature rating for P4KE11C?
The P4KE11C has a maximum junction temperature (TJMAX) of 175°C, allowing reliable operation in high-temperature environments like engine compartments or enclosed industrial enclosures. Derating curves show steady-state power dissipation drops to zero at 175°C, so PCB copper area and airflow must be considered for sustained surge duty cycles.
How does P4KE11C compare to P4KE11A in terms of electrical parameters?
P4KE11C has a VBR range of 9.90–12.1 V and VWM of 8.92 V, while P4KE11A offers tighter VBR (10.5–11.6 V) and higher VWM (9.40 V). Both share identical PPK (400 W), VC (15.6 V for P4KE11A vs. 16.2 V for P4KE11C), and DO-41 packaging. Choose P4KE11C for general-purpose protection; select P4KE11A when higher stand-off margin is needed without increasing clamping voltage.
