Product details
Overview
P6KE39CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 39 V, clamps transients to ≤56.4 V at 11.1 A peak surge current, and delivers <1 μA reverse leakage above 33.3 V standoff voltage - deployed in automotive lighting control modules, industrial PLC I/O protection, and 24 V/48 V power supply input stages.
For engineers reviewing the P6KE39CH datasheet, P6KE39CH pinout, P6KE39CH application, or P6KE39CH equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package thermal derating behavior, 10/1000 µs surge rating, and unidirectional polarity marking for correct PCB orientation during ESD/EFT hardening.
Technical Context
The P6KE39CH implements a silicon avalanche junction optimized for fast clamping response (<1.0 ps rise time from 0 V to VBR) and low dynamic impedance under transient stress. Its unidirectional configuration enables asymmetric protection with cathode-anode polarity, supporting DC-biased circuits where reverse conduction must be blocked.
Thermal performance is defined by a 175 °C maximum junction temperature and 5 W steady-state dissipation at 75 °C ambient on 5 × 5 mm copper pads. The device operates across –55 °C to +175 °C storage and junction ranges, meeting JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 35.1 V / 42.9 V at 1 mA test current - defines guaranteed avalanche initiation window for reliable overvoltage triggering |
| VWM | 31.6 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA, setting safe DC bias margin |
| VC @ IPP | 56.4 V at 11.1 A peak pulse current - clamping voltage limiting downstream component stress during 10/1000 µs transients |
| PPK | 600 W - non-repetitive surge power handling per standard 10/1000 µs waveform, enabling robust lightning/inductive spike suppression |
| IR @ VWM | <1 μA - ultra-low reverse leakage ensuring minimal standby power loss and signal integrity in high-impedance circuits |
| TJ(max) | 175 °C - maximum junction temperature allowing operation in under-hood automotive or enclosed industrial enclosures |
| Package | DO-204AC (DO-15) - axial-leaded through-hole package with tin-plated leads compliant to J-STD-002 solderability |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking; lead spacing 5.0–10.0 mm, body diameter 3.6 mm, total length 9.5 mm. Cathode terminal is marked by a colored band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 600 W 10/1000 µs surge rating | Withstands repeated 600 W transient pulses without parametric shift or catastrophic failure in power rail protection |
| Clamping voltage ≤56.4 V | Ensures downstream 3.3 V/5 V logic ICs and MOSFET gate drivers remain below absolute maximum ratings during surge events |
| Reverse leakage <1 μA at 31.6 V | Minimizes quiescent current draw in battery-powered or energy-sensitive applications such as remote sensors |
| UL Recognized #E-326243 | Meets safety certification requirements for end-equipment compliance in North American industrial and transportation systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Surface-mount SMB package; 36 V standoff; 600 W rating; bidirectional configuration | Requires PCB redesign for SMT placement; suitable for space-constrained designs needing bidirectional protection | Select when board real estate is limited and bidirectional clamping is acceptable for the circuit topology |
| 1.5KE39A | Same DO-15 package; 39 V nominal; 1500 W rating; higher clamping voltage (60.0 V); no AEC-Q101 qualification | Higher surge capacity but larger VC margin; lacks automotive qualification and tighter leakage spec | Choose for cost-sensitive industrial applications where 1500 W surge headroom outweighs AEC-Q101 and leakage requirements |
Compared with SMBJ36A and 1.5KE39A, the P6KE39CH provides AEC-Q101 validation, lower clamping voltage (56.4 V vs. 60.0 V), and sub-1 μA leakage at rated VWM, making it optimal for automotive and low-power industrial systems requiring certified reliability and precision voltage limiting.

FAQ
What is the clamping voltage of the P6KE39CH under maximum surge conditions?
The P6KE39CH clamps to a maximum of 56.4 V when subjected to its rated 11.1 A peak pulse current (IPP) using the standard 10/1000 µs waveform. This value is measured at the device terminals under specified test conditions and ensures downstream components remain within safe operating limits during transient events. The P6KE39CH maintains this clamping performance across its full operating temperature range.
Is the P6KE39CH suitable for automotive applications?
Yes, the P6KE39CH is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and lighting modules. Its construction meets automotive reliability requirements for temperature cycling, high-temperature reverse bias, and mechanical robustness. The P6KE39CH is explicitly designated with the "H" suffix to indicate AEC-Q101 compliance per the manufacturer's ordering code.
How does the P6KE39CH differ from the P6KE39A variant?
The P6KE39CH differs from P6KE39A in three key ways: it carries AEC-Q101 qualification (denoted by the "H" suffix), uses green molding compound (halogen-free per IEC 61249-2-21), and is supplied in tape-and-reel packaging (3,500 units). Electrically, both share identical VBR, VWM, and VC specifications, but the P6KE39CH is validated for automotive-grade stress testing while P6KE39A is intended for general industrial use.
What is the maximum reverse leakage current for the P6KE39CH at its rated standoff voltage?
The P6KE39CH exhibits a maximum reverse leakage current of 1 μA when biased at its rated standoff voltage of 31.6 V (VWM). This ultra-low leakage supports energy-efficient designs, particularly in battery-backed or always-on systems where standby current must be minimized. The P6KE39CH achieves this performance while maintaining full 600 W surge capability and AEC-Q101 qualification.
Can the P6KE39CH be used in bidirectional protection configurations?
No, the P6KE39CH is a unidirectional TVS diode and is not suitable for bidirectional protection. Its cathode-band marking indicates polarity-sensitive installation, and it only clamps in the reverse direction. For bidirectional applications, engineers should select the CA-suffixed variant (e.g., P6KE39CA) or alternate families like SMBJ36CA. Using the P6KE39CH in AC-coupled or symmetrical signal paths risks forward conduction and failure.
