Product details
Overview
P4KE36C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 36V nominal standoff voltage, 400W peak pulse power rating at 10/1000μs, clamping voltage of 52.0V at 8.0A 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 P4KE36C datasheet, P4KE36C pinout, P4KE36C application, or P4KE36C equivalent, key selection criteria include bidirectional clamping capability, low leakage (<1μA at 29.1V), fast response time (<5.0ns), DO-41 package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P4KE36C implements a silicon avalanche diode structure optimized for bidirectional transient suppression, with symmetrical breakdown characteristics in both polarities. Its VBR min/max of 32.4V–39.6V at 1mA test current ensures consistent clamping behavior under reverse and forward surges.
It delivers 400W non-repetitive peak pulse power per ANSI/IEEE C62.35 standard using a 10/1000μs waveform, with thermal derating above 25°C ambient and maximum junction temperature limited to 175°C. The device exhibits <1μA reverse leakage at its 29.1V working stand-off voltage, supporting low-power system integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 36V - defines rated standoff level before avalanche conduction begins in either polarity |
| Breakdown Voltage (VBR) | 32.4V–39.6V @ 1mA - ensures reliable triggering across manufacturing tolerance and temperature |
| Working Stand-off Voltage (VWM) | 29.1V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| Clamping Voltage (VC) | 52.0V @ 8.0A IPPM - limits downstream circuit voltage during 10/1000μs transients to safe levels |
| Peak Pulse Power (PPK) | 400W - sustains single high-energy surges per IEEE C62.35 without failure |
| Junction Temperature Range | –55°C to +175°C - enables operation in under-hood automotive and industrial environments |
| Response Time | <5.0ns - reacts faster than most microcontroller I/O or analog front-end damage thresholds |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability.

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 SMAJ36CA | Same DO-214AC (SMA) package; 400W rating; VBR = 40.0–44.2V; VC = 58.1V @ 6.9A | Higher clamping voltage reduces margin for 36V-rated ICs; better suited for 48V systems | Select when board layout uses surface-mount SMA footprint and higher VC is acceptable |
| ON Semiconductor 1.5KE36CA | DO-201AD package; 1500W rating; VBR = 32.4–39.6V; VC = 52.0V @ 28.8A | Higher surge capacity but larger footprint and thermal mass; not AEC-Q101 qualified | Choose for non-automotive 1500W surge immunity where PCB space allows larger leaded package |
Compared with SMAJ36CA and 1.5KE36CA, the P4KE36C offers optimal balance of compact DO-41 through-hole fit, precise 36V clamping, AEC-Q101 availability, and proven reliability in constrained automotive and industrial enclosures.

FAQ
What does the 'C' suffix indicate in P4KE36C?
The 'C' suffix in P4KE36C denotes bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities without cathode marking. This distinguishes it from unidirectional variants like P4KE36, which require correct orientation during placement and exhibit different forward voltage behavior. The P4KE36C maintains identical VBR and VC values regardless of voltage polarity applied across its terminals.
Is P4KE36C AEC-Q101 qualified?
The base P4KE36C is not automatically AEC-Q101 qualified; qualification applies only to versions marked with an 'H' suffix, such as P4KE36CH. That variant undergoes full stress testing per AEC-Q101 Rev D, including HTGB, TCT, and HTRB. Standard P4KE36C meets industrial reliability standards and shares identical electrical specs, but automotive programs must specify P4KE36CH to ensure compliance documentation and lot-level qualification records.
How does P4KE36C compare to P4KE36A?
P4KE36A is a tighter-tolerance unidirectional variant with VBR = 34.2–37.8V and VWM = 30.8V, whereas P4KE36C is bidirectional with VBR = 32.4–39.6V and VWM = 29.1V. The P4KE36C's broader breakdown range accommodates symmetrical performance but results in slightly lower standoff voltage. Both share identical 400W rating, DO-41 package, and thermal limits - selection depends on circuit polarity requirements and noise margin needs.
What is the maximum peak pulse current (IPPM) for P4KE36C?
The maximum peak pulse current (IPPM) for P4KE36C is 8.0A under the standard 10/1000μs double-exponential waveform, corresponding to its 400W peak pulse power rating. This value is derived from the clamping voltage (VC = 52.0V) and calculated as IPPM = PPK / VC = 400W / 52.0V ≈ 7.69A, rounded to 8.0A per datasheet specification. Derating applies above 25°C ambient per Figure 2.
Can P4KE36C be used in AC line protection?
Yes, P4KE36C is suitable for AC line protection in low-voltage auxiliary supplies (e.g., 24VAC control circuits), provided the RMS voltage remains below its 29.1V working stand-off voltage. Its bidirectional nature allows direct placement across AC lines without rectification. However, for mains-connected 120/230VAC applications, higher-voltage TVS devices (e.g., P4KE350C) or hybrid MOV-TVSS solutions are required to avoid continuous conduction and thermal runaway.
