Product details
Overview
P6KE120AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in power supply input stages and DC bus protection. It features a 120V nominal breakdown voltage (VBR min/max: 108–132V), 97.2V stand-off voltage (VWM), 165V maximum clamping voltage at 3.8A peak surge current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE120AH datasheet, P6KE120AH pinout, P6KE120AH application, or P6KE120AH equivalent, this device is selected for high-energy ESD and lightning surge protection where fast response (<1.0ps), low dynamic impedance, and stable junction temperature up to +175°C are required in DO-15 surface-mount-compatible through-hole layouts.
Technical Context
The P6KE120AH operates as a silicon avalanche diode with unidirectional polarity and single-die construction in a DO-204AC (DO-15) package. Its clamping action begins at VBR ≥108V under 1mA test current and limits transients to ≤165V at 3.8A (10/1000μs waveform), delivering 600W non-repetitive surge capability with <1μA reverse leakage above 102V.
Thermal performance is rated for junction temperatures from –55°C to +175°C, with derating applied above 25°C ambient per Fig.2. The device meets UL 94V-0 flammability, JESD201 Class 2 whisker resistance, and RoHS/halogen-free compliance per IEC 61249-2-21 - critical for automotive and industrial control board deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 97.2 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC blocking threshold. |
| VBR (min/max) | 108 / 132 V - Breakdown occurs within this range at 1 mA; ensures predictable clamping onset across manufacturing lot. |
| VC @ IPP | 165 V at 3.8 A - Peak clamped voltage during 10/1000μs surge; determines protected circuit's maximum transient exposure. |
| PPK | 600 W - Non-repetitive surge power rating; supports IEC 61000-4-5 Level 4 (4kV) surge immunity testing. |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; minimizes standby power loss in high-impedance sensing paths. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in engine bay or enclosed power converter environments. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with tin-plated leads; compatible with wave soldering per J-STD-002. |
Pinout & Package
DO-204AC (DO-15) package with axial leads: Cathode indicated by band-marked end; anode is unmarked lead. Mounting requires 5×5 mm copper pads per terminal for full 5W steady-state dissipation at TA = 75°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient clamp output node | Connected to protected line (e.g., +12V rail); conducts avalanche current to ground during overvoltage events. |
| Anode (unmarked end) | Reference / return path | Typically tied to system ground or low-side reference; completes clamping loop during surge conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements - supports PPAP documentation. |
| Clamping voltage ≤165V @ 3.8A | Ensures downstream 150V-rated MOSFETs or controllers remain within safe operating area during 4kV IEC 61000-4-5 surges. |
| Response time <1.0 ps | Activates faster than most microsecond-scale transients - prevents voltage overshoot before protection ICs react. |
| UL Recognized #E-326243 | Meets safety agency requirements for end-equipment certification in industrial and transportation applications. |
| Halogen-free & RoHS | Complies with environmental directives and eliminates corrosive halogen emissions during thermal failure or rework. |
Applications
| Automotive Power Input Protection | Industrial DC Bus Clamping |
|---|---|
|
Use Scenario: 12V/24V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator switching spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power rail upstream of DC-DC converters and microcontrollers. Use Value: Limits transients to ≤165V, preventing latch-up or gate oxide damage in 3.3V/5V logic and 40V-rated power FETs. |
Use Scenario: 48V telecom or factory automation DC distribution buses subject to inductive kickback from solenoid drivers. IC Role / Device Role / Timing Role: Unidirectional TVS placed across bus rails to absorb energy from relay coil de-energization. Use Value: Absorbs 600W surge without degradation, maintaining bus stability and avoiding false resets in PLC I/O modules. |
| Lighting System Surge Suppression | ESD Protection for Sensor Interfaces |
|
Use Scenario: LED driver inputs in streetlight or headlamp modules subjected to lightning-induced surges on long outdoor wiring. IC Role / Device Role / Timing Role: First-line defense against differential-mode transients entering via AC/DC front-end or DC input terminals. Use Value: Clamps 10/1000μs surges to safe levels while sustaining 175°C junction temperature during extended outdoor operation. |
Use Scenario: CAN/LIN transceiver power pins in vehicle cabin sensors exposed to human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Secondary protection stage after ferrite bead filtering, shunting fast ESD pulses to ground. Use Value: Sub-1ps response captures ESD rise times before transceiver internal protection triggers, reducing cumulative stress. |
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 120V nominal, DO-214AC (SMA) package; 165V VC @ 3.8A; 600W rating; AEC-Q101 qualified. | Surface-mount only; requires PCB re-layout; lower thermal mass than DO-15 for same power handling. | Select when space-constrained designs prioritize SMT assembly over through-hole robustness. |
| Vishay 1.5KE120A | Same 120V rating, DO-201AD package; 165V VC @ 3.8A; 1500W peak power; no AEC-Q101 qualification. | Higher surge rating but larger footprint; lacks automotive qualification; higher leakage (~5μA @ VWM). | Select for cost-sensitive industrial applications where AEC-Q101 is not mandated and higher single-pulse margin is needed. |
Compared with SMAJ120A and 1.5KE120A, the P6KE120AH offers identical clamping performance and AEC-Q101 validation in a proven DO-15 through-hole package - ideal for legacy automotive harness interfaces and high-reliability repairable assemblies requiring mechanical retention strength.

FAQ
What is the maximum clamping voltage of the P6KE120AH under surge conditions?
The P6KE120AH has a maximum clamping voltage (VC) of 165 V when subjected to a 3.8 A peak pulse current with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 165 V during standardized surge events - a key parameter verified in every P6KE120AH production lot.
Is the P6KE120AH suitable for automotive applications?
Yes, the P6KE120AH is AEC-Q101 qualified, making it suitable for automotive powertrain, body control, and lighting modules. Its –55°C to +175°C junction temperature range, UL recognition (#E-326243), and halogen-free construction meet stringent OEM requirements - confirmed in TSC's P2203 qualification report for the P6KE-H series.
How does the P6KE120AH differ from the non-AEC-Q101 P6KE120A variant?
The P6KE120AH adds AEC-Q101 qualification, including extended temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - while retaining identical electrical specs (VBR: 108–132 V, VC: 165 V, PPK: 600 W) and DO-15 packaging as the P6KE120A. Only the 'H' suffix denotes automotive qualification.
What is the reverse leakage current specification for the P6KE120AH at its stand-off voltage?
The P6KE120AH exhibits a maximum reverse leakage current (ID) of 1 μA when biased at its 97.2 V stand-off voltage (VWM) and tested at 25°C. This ultra-low leakage preserves efficiency in always-on circuits and avoids false triggering in high-impedance monitoring paths - a value confirmed in TSC's electrical specifications table on page 3 of the P2203 datasheet.
Can the P6KE120AH be used in bidirectional configurations?
No, the P6KE120AH is unidirectional only, as indicated by its part number suffix and cathode band marking. For bidirectional protection, TSC specifies CA-suffixed variants (e.g., P6KE120CA); using P6KE120AH in reverse-biased mode risks permanent breakdown due to lack of symmetrical avalanche structure.
