Product details
Overview
P6KE16C from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 16V nominal breakdown voltage (VBR = 14.4–17.6V at IT = 1mA), 12.9V stand-off voltage (VWM), clamps to ≤23.5V at 26A peak surge current, and uses a DO-204AC (DO-15) axial package for industrial power supply input stage protection.
For engineers reviewing the P6KE16C datasheet, P6KE16C pinout, P6KE16C application, or P6KE16C equivalent, key selection criteria include its 10/1000μs waveform surge rating, low dynamic impedance, sub-1ps response time from 0V to VBR, <1μA leakage above 10V, and AEC-Q101 qualification availability - critical for automotive front-end ESD and load-dump immunity design.
Technical Context
The P6KE16C operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified VBR range. Its clamping action limits transient energy by diverting surge current away from downstream circuitry while maintaining a predictable VC ≤23.5V at IPP = 26A under 10/1000μs waveform conditions.
Thermal performance is defined by a 175°C maximum junction temperature and derated pulse power above 25°C ambient per Fig.2. The device meets UL 94V-0 flammability standards, uses pure tin-plated leads compliant with J-STD-002, and passes JESD201 Class 2 whisker testing - confirming suitability for high-reliability PCB assembly environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.9 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets safe DC rail margin below clamping threshold |
| VBR (min/max) | 14.4 V / 17.6 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering across process and temperature variation |
| VC @ IPP | 23.5 V at 26 A - Peak clamped voltage during 10/1000μs surge; defines worst-case stress on protected IC inputs |
| PPK | 600 W - Non-repetitive surge power handling capability; supports single-event transients like ISO 7637-2 Pulse 1/2a/5a |
| IR @ VWM | <1 μA - Ultra-low reverse leakage at rated stand-off; prevents excessive quiescent power loss in battery-powered systems |
| Response Time | <1.0 ps - Time from 0 V to VBR under fast-rising transients; enables protection against ESD events per IEC 61000-4-2 |
| Package | DO-204AC (DO-15) - Axial-leaded through-hole package with 0.400 g mass; compatible with standard wave-solder and hand-solder processes |
Pinout & Package

IC Role / Device Role / Timing Role: Front-end TVS on isolated digital input channel, shunting surge energy before optocoupler or Schmitt trigger input. Use Value: Clamps 10/1000μs transients to safe levels within 1ps, preserving signal integrity and eliminating false triggering in real-time control logic. |
| LED Driver Overvoltage Clamp | ESD-Sensitive Sensor Interface |
Use Scenario: Constant-current LED driver ICs powered from unregulated 12–24V supplies in outdoor signage with lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed across driver input capacitor to absorb line-side transients before regulation stage. Use Value: Withstands 600W surges while maintaining VWM = 12.9V, ensuring stable operation during normal dimming cycles and surviving infrequent surge events. | Use Scenario: Analog temperature/humidity sensors connected via long cables in factory automation, vulnerable to IEC 61000-4-2 ±8kV contact ESD. IC Role / Device Role / Timing Role: Localized TVS at sensor connector interface, directly shunting ESD current before analog front-end amplifier. Use Value: Sub-1ps response captures ESD rise time (<1ns), limiting coupled voltage to ≤23.5V and preventing latch-up or gate oxide damage in precision ADCs. |
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 P6KE16A | Narrower VBR range (15.2–16.8V), tighter VWM = 13.6V, same DO-15 package and 600W rating | Slightly higher stand-off margin; preferred where precise 16V rail tolerance is required | Select P6KE16A when tighter VBR distribution improves margin against nuisance tripping in low-noise analog rails |
| ON Semiconductor 1.5KE16A | Same VBR/VWM specs but 1500W peak power rating; larger DO-201AD package (axial, longer body) | Higher surge capacity suits harsher environments (e.g., railway traction power); requires PCB layout change | Choose 1.5KE16A only if system-level surge testing exceeds 600W requirements and board space allows larger footprint |
Compared with P6KE16C, P6KE16A offers improved VBR consistency for tighter voltage-margin designs, while 1.5KE16A trades package compatibility for higher surge headroom - making P6KE16C the optimal balance of proven reliability, DO-15 fit, and 600W capability in space-constrained automotive and industrial layouts.

FAQ
What is the maximum clamping voltage of the P6KE16C under surge conditions?
The P6KE16C has a maximum clamping voltage (VC) of 23.5 V when subjected to a 26 A peak pulse current with a 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the worst-case voltage seen by downstream components during standardized surge events - a critical parameter for verifying safe operation of 24V-rated ICs in the protected circuit.
Is the P6KE16C unidirectional or bidirectional, and how is polarity identified?
The P6KE16C is a unidirectional TVS diode, indicated by the "C" suffix per TSC's ordering nomenclature. Polarity is marked by a cathode band on the DO-204AC (DO-15) package body; the banded end connects to the protected line (cathode), while the unbanded end connects to ground (anode). Bidirectional variants use "CA" suffixes (e.g., P6KE16CA).
Does the P6KE16C meet automotive reliability standards?
The P6KE16C itself is not AEC-Q101 qualified, but the P6KE16CH variant (with "H" suffix) is explicitly listed as AEC-Q101 qualified in TSC's ordering guide. For automotive under-hood applications requiring qualification, P6KE16CH must be selected - it shares identical electrical specs and DO-15 packaging but undergoes extended stress testing per AEC-Q101 Rev D.
What is the thermal derating behavior of the P6KE16C above 25°C ambient?
The P6KE16C's peak pulse power rating decreases linearly above 25°C ambient temperature, following the derating curve in Figure 2 of the datasheet. At 75°C, its 600W rating drops to approximately 450W; at 125°C, it falls to ~250W. This derating applies to non-repetitive pulses and must be factored into system-level thermal design for high-temperature enclosures or densely packed PCBs.
Can the P6KE16C be used in place of the P6KE16A, and what is the key difference?
Yes, the P6KE16C can be used in place of the P6KE16A in most applications, but with a trade-off in VBR tolerance: P6KE16C specifies VBR = 14.4–17.6V, while P6KE16A tightens this to 15.2–16.8V. Both share identical VWM = 12.9V/13.6V, VC = 23.5V/22.5V, and DO-15 packaging. Use P6KE16C where broader VBR spread is acceptable; choose P6KE16A for tighter voltage-margin designs.
