Product details
Overview
P6KE120CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supply input stages and DC bus lines. It features a 120V nominal breakdown voltage (VBR min/max: 108–132V), 97.2V stand-off voltage (VWM), 173V maximum clamping voltage at 3.6A peak surge current, and DO-204AC (DO-15) axial package. It is AEC-Q101 qualified and used in automotive body control modules to protect CAN transceivers from load dump transients.
For engineers reviewing the P6KE120CH datasheet, P6KE120CH pinout, P6KE120CH application, or P6KE120CH equivalent, key selection criteria include clamping voltage margin relative to system rail, surge current rating under 10/1000μs waveform, AEC-Q101 qualification status, thermal derating above 25°C ambient, and compatibility with lead-free reflow profiles per J-STD-002.
Technical Context
The P6KE120CH operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its VBR threshold and clamping transient energy into its junction. Its low dynamic impedance ensures rapid voltage stabilization during EFT or ISO 7637-2 pulse 5a events.
It is rated for non-repetitive 600W peak pulse power at 10/1000μs, with junction temperature range from –55°C to +175°C and maximum reverse leakage of 1μA at 97.2V. The device uses a single-die DO-204AC construction with pure tin-plated leads and UL 94V-0 molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 108–132 V - Ensures reliable conduction onset across manufacturing tolerance and temperature variation |
| VWM | 97.2 V - Maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPPM | 173 V at 3.6 A - Clamped voltage seen by protected IC during worst-case 10/1000μs surge; defines voltage stress on downstream circuitry |
| PPK | 600 W - Peak transient power dissipation capability under standardized 10/1000μs waveform |
| IR @ VWM | <1 μA - Negligible standby leakage, critical for low-power always-on systems like automotive wake-up circuits |
| TJ max | +175 °C - Enables operation in high-temperature engine bay environments without thermal shutdown |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Dimensions per JEDEC DO-15 outline; weight ≈ 0.400 g. Complies with UL 94V-0 flammability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current path / low-impedance return during clamping | Connected to system ground or low-side reference; must handle 3.6A surge current without trace fusing |
| Cathode (banded end) | Transient voltage sensing node / clamping anode | Connected to protected line (e.g., 12V battery rail); initiates avalanche conduction when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, high-temp reverse bias, and mechanical shock |
| Clamping voltage (VC) | 173 V at 3.6 A - Limits voltage overshoot to safe levels for 12V/24V system ICs with 180V absolute max ratings |
| Response time | <1.0 ps - Faster than most ESD events, enabling protection of high-speed interfaces upstream of TVS |
| Surge waveform compliance | Rated for 10/1000μs per IEC 61000-4-5 and ISO 7637-2 Pulse 5a - Matches real-world automotive load dump profiles |
| RoHS & halogen-free | Complies with IEC 61249-2-21 - Supports green manufacturing and end-of-life recycling requirements |
Applications
| Automotive Load Dump Protection | Industrial DC Power Input Protection |
|---|---|
Use Scenario: 12V battery rail in BCM exposed to ISO 7637-2 Pulse 5a (load dump up to 60V for 400ms). IC Role / Device Role / Timing Role: Primary clamping device placed between battery feed and LDO/regulator input. Use Value: Clamps peak voltage to 173V, preventing damage to 180V-rated power management ICs while surviving repeated surges. |
Use Scenario: 24V DC input stage of PLC I/O module subjected to inductive switching transients from solenoid drivers. IC Role / Device Role / Timing Role: First-line transient absorber ahead of input filter capacitor and DC-DC converter. Use Value: Absorbs 600W surge energy within 10/1000μs window, limiting voltage rise to <173V and preserving downstream isolation barrier integrity. |
| LED Driver Overvoltage Clamp | Telecom Line Card Surge Suppression |
Use Scenario: Constant-current LED driver board powered from 48V telecom supply experiencing hot-swap transients. IC Role / Device Role / Timing Role: Unidirectional clamp across input terminals to limit voltage excursion during connector insertion. Use Value: Sub-1μA leakage avoids false triggering of undervoltage lockout; 173V VC protects 60V-rated MOSFET gate drivers. |
Use Scenario: -48V DC power feed to line card in central office equipment facing lightning-induced surges. IC Role / Device Role / Timing Role: Secondary protection element after gas discharge tube (GDT), providing fast low-clamp backup. Use Value: Responds in <1ps to clamp residual transients missed by GDT's slower response, ensuring <173V stress on PMIC and PHY ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A | 600W rating, same VBR (108–126V), but SMB package (surface-mount); lower thermal resistance than DO-15 | Preferred for automated SMT assembly; less suitable for high-vibration through-hole mounting | Select SMBJ120A when PCB space is constrained and reflow profile supports SMB footprint. |
| 1.5KE120A | Same DO-204AC package and VBR range, but 1500W rating (1.5kW); higher IPP (10.5A vs 3.6A) and VC (193V vs 173V) | Better for extreme surge environments (e.g., railway traction power), but larger voltage overshoot during clamping | Choose 1.5KE120A only if system requires >600W surge handling and can tolerate 193V clamping. |
Compared with SMBJ120A and 1.5KE120A, the P6KE120CH offers optimal balance of AEC-Q101 qualification, compact DO-15 form factor, and tight 173V clamping-making it ideal for cost-sensitive, vibration-prone automotive and industrial applications where precise voltage limiting is critical.

FAQ
What does the 'H' suffix in P6KE120CH signify?
The 'H' suffix in P6KE120CH indicates full AEC-Q101 qualification per Rev D standards-including temperature cycling, high-temperature reverse bias, and ESD testing. This distinguishes it from standard P6KE120C, which lacks automotive-grade validation. The P6KE120CH is certified for under-hood deployment where ambient temperatures reach +125°C and mechanical shock is routine.
How does P6KE120CH differ from P6KE120A?
The P6KE120CH and P6KE120A share identical electrical specs (VBR 108–132V, VC = 173V, PPK = 600W) and DO-204AC packaging, but only the 'H' variant is AEC-Q101 qualified. The 'A' suffix denotes tighter VBR tolerance (114–126V vs 108–132V), while 'H' adds automotive reliability validation. For non-automotive industrial use, P6KE120A may suffice; for automotive, P6KE120CH is mandatory.
Can P6KE120CH be used in bidirectional configurations?
No-P6KE120CH is unidirectional only, with cathode band marking indicating polarity. Bidirectional operation requires CA-suffixed parts like P6KE120CA, which feature symmetrical breakdown in both directions. Using P6KE120CH in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles.
What is the maximum allowable PCB trace width for P6KE120CH anode connection?
To safely conduct the 3.6A peak surge current without thermal failure, the anode trace should be ≥2.0 mm wide with 2 oz copper and internal thermal vias to inner ground planes. Per JEDEC standards, the DO-204AC lead-to-trace interface must maintain ≥0.5 mm solder fillet height to avoid solder joint fracture under thermal cycling-verified in P6KE120CH's AEC-Q101 mechanical shock testing.
Does P6KE120CH meet UL 94V-0 flammability requirements?
Yes-P6KE120CH's epoxy molding compound meets UL 94V-0 flammability rating, confirmed in the mechanical data section of the official Taiwan Semiconductor datasheet (Version P2203). This ensures self-extinguishing behavior within 10 seconds after flame removal, a requirement for enclosures in automotive and industrial safety-critical systems.
