Product details
Overview
P6KE400CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 400V nominal standoff voltage (VWM = 324V), 360–440V breakdown range (VBR), clamps to ≤574V at 1A peak pulse current, and uses DO-204AC (DO-15) package for industrial power supply input protection.
For engineers reviewing the P6KE400CH datasheet, P6KE400CH pinout, P6KE400CH application, or P6KE400CH equivalent, this AEC-Q101 qualified TVS offers verified 10/1000μs surge immunity, low dynamic impedance, and sub-1ps response time - critical for automotive body electronics, industrial PLC I/O protection, and AC/DC front-end EFT hardening.
Technical Context
The P6KE400CH operates as a unidirectional avalanche diode with precise VBR min/max of 360V–440V at 1mA test current and maximum clamping voltage VC of 574V at IPP = 1.0A under 10/1000μs waveform. Its junction temperature rating extends to +175°C, supporting operation in under-hood automotive environments and high-ambient industrial enclosures.
It exhibits <1μA reverse leakage at 324V (VWM), a temperature coefficient of VBR at 0.110%/°C, and meets UL 94V-0 flammability requirements in its molded DO-204AC case. Polarity is marked by cathode band; terminals are pure tin-plated per J-STD-002 solderability standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 324 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin. |
| VBR (min/max) | 360 V / 440 V - Breakdown occurs within this range at 1 mA; ensures predictable turn-on during transients. |
| VC @ IPP = 1.0A | ≤574 V - Clamped voltage during 10/1000μs surge; determines protected circuit's maximum stress level. |
| PPK | 600 W - Peak pulse power handling at 10/1000μs; supports IEC 61000-4-5 Level 4 surges. |
| IR @ VWM | <1 μA - Ultra-low leakage preserves system efficiency and minimizes standby power loss. |
| TJ max | +175 °C - Enables placement near heat sources (e.g., rectifiers, transformers) without derating. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400g mass and UL 94V-0 molding compound. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, epoxy-molded, cathode indicated by band-marked end. Leads are pure tin-plated, compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current path / ground reference | Connected to circuit ground or low-side return; conducts during positive transients on cathode side. |
| Cathode (banded end) | Protected line connection | Connected to line being protected (e.g., 400V DC bus); avalanches into conduction when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and body electronics per stress test requirements. |
| 600W 10/1000μs surge rating | Withstands IEC 61000-4-5 Level 4 (4kV/2Ω) surges without degradation when properly heatsinked. |
| Sub-1ps response time (unidirectional) | Activates faster than most microsecond-scale transients, limiting voltage overshoot before downstream ICs react. |
| Low dynamic impedance | Ensures stable clamping performance across varying surge amplitudes and repetition rates. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ400A | Same DO-214AC package; lower PPK (400W), higher VC (612V @ 1A), non-AEC-Q101 rated. | Not qualified for automotive under-hood use; suitable for commercial telecom or lighting. | Select when cost sensitivity outweighs AEC-Q101 compliance and 600W headroom is unnecessary. |
| ON Semiconductor 1.5KE400A | Higher PPK (1500W), same VWM/VBR range, DO-201AD package (larger footprint, higher thermal mass). | Requires PCB layout change; better for high-repetition surge environments like factory automation. | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 or thermal cycling demands greater robustness. |
Compared with SMAJ400A and 1.5KE400A, the P6KE400CH uniquely balances AEC-Q101 qualification, DO-204AC compactness, and 600W capability - making it optimal for space-constrained automotive and industrial modules where certification and reliability are non-negotiable.

FAQ
What is the maximum clamping voltage of the P6KE400CH under standard test conditions?
The P6KE400CH has a maximum clamping voltage (VC) of 574 V when subjected to a 10/1000μs surge waveform at 1.0 A peak pulse current. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during transient events. The P6KE400CH maintains this clamping performance across its full operating temperature range.
Is the P6KE400CH suitable for bidirectional transient protection?
No, the P6KE400CH is a unidirectional TVS diode, indicated by the "H" suffix and absence of "CA" or "C" designation. It conducts only when the cathode is driven positive relative to the anode. For bidirectional protection at 400V standoff, the P6KE400A variant must be used instead. The P6KE400CH is optimized for DC rail protection where polarity is fixed.
Does the P6KE400CH meet automotive qualification standards?
Yes, the P6KE400CH is AEC-Q101 qualified, as confirmed in the ordering information section of the official Taiwan Semiconductor datasheet (Version P2203). This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock - validating its suitability for automotive powertrain and body electronics applications.
What is the reverse leakage current specification for the P6KE400CH at rated standoff voltage?
The P6KE400CH exhibits a maximum reverse leakage current (ID) of 1 μA when biased at its rated standoff voltage (VWM = 324 V) and ambient temperature of 25°C. This ultra-low leakage ensures minimal impact on system standby power consumption and prevents false triggering in high-impedance sensing circuits.
What packaging options are available for the P6KE400CH?
The P6KE400CH is supplied in DO-204AC (DO-15) package format, available in two configurations: 3,500 units per tape-and-reel (P6KE400CH) and 1,500 units per ammo box (P6KE400CHA0G). Both variants feature pure tin-plated leads, UL 94V-0 molding compound, and cathode band marking per JEDEC standards.
