Product details
Overview
P6KE120A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supply inputs, DC bus lines, and automotive electronics. It features a 120V nominal breakdown voltage (VBR min/max = 114–126V), 102V maximum standoff voltage (VWM), 165V clamping voltage at 3.8A peak surge current, and operates across –55°C to +175°C junction temperature range.
For engineers reviewing the P6KE120A datasheet, P6KE120A pinout, P6KE120A application, or P6KE120A equivalent, this device is selected for high-energy ESD and lightning surge suppression where fast response (<1.0ps), low dynamic impedance, and AEC-Q101 qualification (H-suffix variant) are critical in industrial power converters and automotive body control modules.
Technical Context
The P6KE120A employs a planar junction silicon avalanche structure optimized for unidirectional clamping with tightly controlled VBR tolerance (±5% for "A" grade). Its 10/1000μs waveform surge rating of 600W is derated linearly above 25°C ambient per Fig.2, maintaining reliable operation up to 175°C junction temperature.
Clamping performance is defined by VC = 165V at IPP = 3.8A, with reverse leakage ID ≤ 1μA at VWM = 102V and temperature coefficient of VBR = 0.107%/°C - enabling stable voltage threshold behavior across wide thermal operating ranges in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 114 V / 126 V - Ensures consistent avalanche initiation within ±5% tolerance at IT = 1 mA |
| VWM | 102 V - Maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPP | 165 V at 3.8 A - Clamped voltage during 10/1000μs surge; defines worst-case stress on downstream circuitry |
| PPK | 600 W - Peak pulse power handling capability under standardized 10/1000μs waveform |
| ID @ VWM | ≤ 1 μA - Ultra-low leakage ensures minimal standby power loss and signal integrity in high-impedance nodes |
| TJ max | +175 °C - Enables use in under-hood automotive and high-temperature industrial power stages without derating |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads compliant to J-STD-002 solderability |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking; polarity-sensitive unidirectional configuration. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; defines reference for clamping action |
| Cathode | Protected line input | Connected to line being protected (e.g., 120V DC bus); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (H-suffix) | Validated for automotive applications including engine control units and body electronics per stress test requirements |
| Clamping time <1.0 ps | Sub-picosecond response enables suppression of nanosecond-scale ESD transients before IC damage occurs |
| Low dynamic impedance | Minimizes voltage overshoot during surge events, improving protection margin for sensitive downstream components |
| UL 94V-0 molding compound | Flame-retardant encapsulation meets safety standards for enclosed power systems and industrial enclosures |
| Halogen-free (IEC 61249-2-21) | Complies with environmental regulations for RoHS-compliant manufacturing and end-of-life recycling |

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 SMAJ120A | Same DO-214AC package; 120V VBR (114–126V), 165V VC @ 3.8A, but rated for 400W PPK (vs. 600W) | Lower surge rating limits use in high-energy industrial transients; suitable only where 400W margin is sufficient | Select P6KE120A when full 600W 10/1000μs surge headroom is required; choose SMAJ120A for space-constrained SMD layouts |
| ON Semiconductor 1.5KE120A | Same DO-204AC package; identical VBR/VWM/VC specs, but rated for 1500W PPK and higher IPP (10.3A) | Higher surge capacity supports repeated surge events in utility metering or grid-tied inverters | Choose 1.5KE120A for applications requiring >600W single-pulse or multi-pulse endurance; P6KE120A offers tighter thermal profile and AEC-Q101 option |
Compared with SMAJ120A and 1.5KE120A, P6KE120A delivers optimal balance of 600W surge capability, AEC-Q101 qualification, and DO-15 through-hole reliability - making it preferred for automotive and industrial designs where proven long-term surge endurance and qualification compliance are mandatory.

FAQ
What is the maximum clamping voltage of P6KE120A under standard surge conditions?
The P6KE120A has a maximum clamping voltage (VC) of 165 V when subjected to a 10/1000μs surge waveform at a peak current (IPP) of 3.8 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6KE120A suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P6KE120A is available in an AEC-Q101 qualified version designated by the "H" suffix (e.g., P6KE120AH). While the base P6KE120A part number itself is not automatically qualified, Taiwan Semiconductor explicitly lists the H-suffix variant as AEC-Q101 compliant in its ordering information - confirming suitability for automotive power modules, body control units, and infotainment power rails.
How does the VBR tolerance of P6KE120A compare to non-"A" grade variants?
The "A" suffix in P6KE120A indicates ±5% breakdown voltage tolerance (VBR = 114–126 V at IT = 1 mA), whereas standard P6KE120 has ±10% tolerance (108–132 V). This tighter specification ensures more predictable clamping onset in precision power protection circuits, reducing design margin uncertainty and improving consistency across production batches.
What is the thermal derating behavior of P6KE120A above 25°C ambient?
P6KE120A follows a linear derating curve per Figure 2 in the datasheet: its 600W peak pulse power rating decreases by approximately 5.3W/°C above 25°C ambient, reaching zero at 135°C ambient. At 75°C ambient, the usable PPK drops to ~330W - a key consideration for enclosed automotive or industrial enclosures with limited airflow.
Can P6KE120A be used in bidirectional configurations?
No, P6KE120A is a unidirectional TVS diode with cathode-band polarity marking and specified only for single-polarity clamping. For bidirectional protection at 120V, Taiwan Semiconductor offers the P6KE120CA variant - which uses a center-tapped dual-die configuration and exhibits symmetrical VBR in both directions (114–126 V each way).
