Product details
Overview
P6KE16AH 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 min/max = 15.2V/16.8V), 13.6V stand-off voltage (VWM), clamps to ≤22.5V at 28A peak surge current, and operates within -55°C to +175°C junction temperature range.
For engineers reviewing the P6KE16AH datasheet, P6KE16AH pinout, P6KE16AH application, or P6KE16AH equivalent, this device is selected for automotive-grade ESD and load-dump protection where AEC-Q101 qualification, low clamping voltage, and fast sub-nanosecond response are critical design requirements.
Technical Context
The P6KE16AH is a single-die, unidirectional TVS diode in DO-204AC (DO-15) package, optimized for high-energy transients per IEC 61000-4-5 (10/1000μs waveform). Its 600W peak pulse power rating is derated linearly above 25°C ambient, with maximum junction temperature of 175°C and thermal resistance (RθJA) of approximately 100°C/W on standard 5×5 mm copper pads.
It exhibits low dynamic impedance and typical reverse leakage <1 μA at 13.6V, enabling minimal standby power loss in always-on circuits. The device responds in <1.0 ps from 0 V to VBR, ensuring effective suppression of fast-rising EFT and ESD events before sensitive downstream ICs are stressed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - Ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 13.6 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC @ IPP | 22.5 V @ 28 A - Clamping voltage during 10/1000μs surge; defines worst-case stress on protected circuit |
| PPK | 600 W - Peak pulse power handling capability under standardized surge waveform |
| IR @ VWM | <1 μA - Negligible standby current draw, critical for battery-powered or low-power systems |
| TJ max | +175 °C - Enables operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB, etc.) |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; forms forward-biased path during negative transients (unidirectional only) |
| Cathode | Protected line input | Connected to line being protected (e.g., 12V rail); conducts avalanche current to ground when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, high-temp operating life, and biased HAST |
| 600W surge rating (10/1000μs) | Withstands ISO 7637-2 Pulse 5a (load dump) up to 120V/350ms in properly designed clamping networks |
| Clamping voltage ≤22.5V @ 28A | Keeps downstream 16V-rated components (e.g., CAN transceivers, microcontrollers) within safe operating area |
| Response time <1.0 ps | Engages before ESD events (IEC 61000-4-2) or EFT bursts (IEC 61000-4-4) propagate into IC pins |
| RoHS & halogen-free | Complies with IPC/JEDEC J-STD-709C and EU Directive 2011/65/EU for green manufacturing |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to ISO 7637-2 load dump and jump-start surges. IC Role / Device Role: Primary clamping element placed between battery input and DC-DC converter input stage. Use Value: Limits transient voltage to ≤22.5V, preventing damage to 36V-input buck controllers and preserving system uptime. | Use Scenario: 4–20mA current loop transmitters interfacing with PLC analog inputs in factory automation. IC Role / Device Role: Line-side TVS on signal pair to absorb induced surges from nearby motor drives or relay switching. Use Value: Maintains signal integrity by clamping transients before they saturate op-amps or damage ADC front-ends. |
| LED Lighting Driver Input Protection | USB-C Power Delivery Port Protection |
Use Scenario: Constant-current LED drivers powered from 24V industrial supplies subject to inductive kickback. IC Role / Device Role: Unidirectional TVS across input terminals to shunt flyback energy from relay coils or solenoids.

IC Role / Device Role: Secondary-level TVS on VBUS line downstream of primary protection, targeting fast ESD events. Use Value: Sub-1ns response ensures clamping occurs before PD PHY logic is corrupted during contact-mode ESD discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same 16V nominal, 600W rating, but SMA package (surface-mount); lower thermal mass and higher RθJA | Requires PCB layout change; unsuitable for through-hole legacy designs or high-reliability mechanical retention | Select SMAJ16A only when board space is constrained and reflow assembly is available. |
| 1.5KE16A | Same DO-15 package and 16V rating, but 1500W peak power; larger die, higher capacitance (~100 pF vs. ~50 pF) | Higher clamping voltage (24.4V) and slower response; less suitable for high-speed data lines or tight-voltage-margin ICs | Choose 1.5KE16A only when surge energy exceeds 600W and clamping voltage margin allows ≥24.4V. |
Compared with SMAJ16A and 1.5KE16A, the P6KE16AH uniquely combines AEC-Q101 qualification, DO-15 through-hole robustness, and 22.5V clamping-making it optimal for automotive body control modules and industrial power supplies where reliability, serviceability, and precise voltage limiting are jointly required.

FAQ
What is the key difference between P6KE16AH and P6KE16A?
The "H" suffix in P6KE16AH denotes AEC-Q101 qualification, verified through accelerated stress testing including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. P6KE16A lacks this automotive qualification and is intended for commercial/industrial use only. Both share identical electrical specs and DO-15 packaging, but P6KE16AH provides documented reliability evidence required for Tier 1 automotive supply chains.
Does P6KE16AH support bidirectional transient suppression?
No, P6KE16AH is a unidirectional TVS diode, indicated by its single cathode band marking and specified VBR/VWM values for forward-blocking operation. For bidirectional protection, TSC offers P6KE16CA (with "CA" suffix), which has symmetrical breakdown in both polarities and no polarity marking. Using P6KE16AH in reverse-biased configurations risks permanent damage due to lack of reverse avalanche capability.
What is the maximum allowable surge current for P6KE16AH at 85°C ambient?
Per the pulse derating curve (Fig.2), P6KE16AH's 600W peak pulse power is derated to ~420W at 85°C ambient, corresponding to a maximum peak surge current of approximately 23.5A (calculated as √(420W ÷ 22.5V)). This value assumes proper PCB thermal relief (5×5 mm copper pads per lead) and single-pulse conditions per IEC 61000-4-5.
Can P6KE16AH be used in parallel for higher surge handling?
No-P6KE16AH is not characterized or recommended for parallel operation. Mismatched dynamic impedance and VBR tolerances (±5%) cause current imbalance, leading to premature failure of one device. For higher surge ratings, select a single higher-power TVS (e.g., 1.5KE16A) or implement staged protection with upstream MOVs and downstream low-capacitance TVS arrays.
Is P6KE16AH compliant with UL 94V-0 and RoHS?
Yes, P6KE16AH's molding compound meets UL 94V-0 flammability rating, and the device is RoHS compliant and halogen-free per IEC 61249-2-21. UL recognition file #E-326243 applies to the entire P6KE series, including P6KE16AH, confirming compliance with UL 497B for surge protective components.
