Product details
Overview
P6KE440A A0G from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge clamping in power and signal lines. It features a 440V nominal breakdown voltage (VBR = 418–462 V), 376V maximum stand-off voltage (VWM), 602V clamping voltage at 1.04A peak surge current, and DO-204AC (DO-15) axial package - deployed in industrial power supply input protection and telecom line surge suppression.
For engineers reviewing the P6KE440A A0G datasheet, P6KE440A A0G pinout, P6KE440A A0G application, or P6KE440A A0G equivalent, key selection criteria include clamping voltage margin vs. system DC rating, 10/1000μs surge capability, unidirectional polarity marking, thermal derating above 25°C, and compliance with AEC-Q101 (not applicable to this variant).
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (418–462 V), it avalanches to limit transient energy by diverting surge current to ground. Its low dynamic impedance ensures rapid voltage stabilization during 10/1000μs transients, while junction temperature range (−55°C to +175°C) supports harsh-environment deployment.
Clamping performance is defined at IPP = 1.04 A (10/1000μs), yielding VC = 602 V - critical for protecting downstream 400–450V-rated components. The device exhibits <1 μA leakage at VWM = 376 V and a VBR temperature coefficient of 0.110 %/°C, enabling predictable drift under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 418 V / 462 V - defines guaranteed avalanche onset window; ensures reliable triggering above system max operating voltage |
| VWM | 376 V - maximum continuous reverse voltage before leakage exceeds 1 μA; sets safe DC operating ceiling |
| VC @ IPP | 602 V at 1.04 A (10/1000μs) - peak clamped voltage seen by protected circuit during rated surge event |
| PPK | 600 W - non-repetitive surge power handling per 10/1000μs waveform; determines single-event robustness |
| IR @ VWM | <1 μA - ultra-low leakage preserves efficiency in high-impedance bias networks and standby circuits |
| TJ max | +175°C - enables operation in enclosed power enclosures or near heat-generating components |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400 g mass; compatible with wave soldering per J-STD-002 |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking on one end. Leads are pure tin-plated, solderable per J-STD-002; polarity is unidirectional - cathode must be connected toward higher potential side of protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Low-side reference terminal | Connected to ground or low-voltage rail; completes clamping path during reverse avalanche |
| Cathode (banded end) | High-side surge input terminal | Connected to protected line; blocks VWM in normal operation, avalanches at VBR during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 600W 10/1000μs surge rating | Enables single-device protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) in AC front-end designs |
| Clamping voltage ≤602 V | Provides ≥38 V margin below 650V-class MOSFET/SiC device breakdown, reducing risk of cascading failure |
| Leakage <1 μA at 376 V | Minimizes standby power loss in always-on industrial controllers and telecom power modules |
| UL 94V-0 molding compound | Meets flammability safety requirements for enclosed power supplies and DIN-rail mounted equipment |
| Junction temp. range −55°C to +175°C | Supports deployment in automotive engine compartments, outdoor base stations, and industrial motor drives |
Applications
| Industrial Power Supply Input Protection | Telecom Line Surge Suppression |
|---|---|
Use Scenario: AC/DC converter input stage exposed to lightning-induced surges on 380VAC mains feeders. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed across bulk capacitor input to clamp differential-mode transients before rectifier bridge.

Use Scenario: 24V analog sensor inputs in PLC modules exposed to ESD and cable discharge events. IC Role / Device Role / Timing Role: Secondary-level TVS on signal line after series resistor, referenced to local ground plane. Use Value: Provides sub-1ns response to ±8kV contact ESD (IEC 61000-4-2), limiting voltage excursion to <602 V at sensor amplifier input. |
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 SMAJ440A | Same VBR (418–462 V), identical DO-214AC package, but 400W PPK rating (vs. 600W) | Lower surge rating limits use to lower-energy threat environments (e.g., IEC 61000-4-5 Level 2) | Select when board space constraints favor SMD or when 400W surge margin suffices for cost optimization |
| ON Semiconductor 1.5KE440A | Same VBR/VWM/VC specs, DO-201AD package, 600W rating, but 1.5A IPP (vs. 1.04A) and higher thermal resistance | Higher IPP allows longer surge duration tolerance; larger DO-201AD footprint may impact layout density | Choose when legacy DO-201AD footprint compatibility is required or when higher IPP margin is prioritized over size |
Compared with P6KE440A A0G, SMAJ440A offers surface-mount convenience at reduced surge capacity, while 1.5KE440A delivers identical clamping performance in a larger axial package with higher peak current headroom - enabling trade-offs between PCB area, thermal management, and surge severity coverage.

FAQ
What is the clamping voltage of P6KE440A A0G at its rated surge current?
The P6KE440A A0G has a maximum clamping voltage (VC) of 602 V when subjected to a 10/1000μs surge current pulse of 1.04 A. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and represents the peak voltage imposed on the protected circuit during worst-case transient events - critical for ensuring downstream components remain within their absolute maximum voltage ratings. The P6KE440A A0G maintains this clamping performance across its full operating temperature range.
Is P6KE440A A0G AEC-Q101 qualified?
No, P6KE440A A0G is not AEC-Q101 qualified. Per Taiwan Semiconductor's ordering information, only variants marked with the "H" suffix (e.g., P6KE440AH) are AEC-Q101 certified. The "A0G" suffix indicates ammo box packaging (1,500 units) in the standard industrial-grade version. For automotive under-hood or chassis applications requiring AEC-Q101 validation, P6KE440AH must be specified instead of P6KE440A A0G.
What is the maximum steady-state power dissipation of P6KE440A A0G at 75°C ambient?
The P6KE440A A0G has a steady-state power dissipation (PD) rating of 5 W at TA = 75°C, measured with lead lengths of 9.5 mm (0.375 inches) and mounted on 5 × 5 mm copper pads per terminal. This rating reflects continuous DC power handling capability - distinct from its 600W non-repetitive surge rating. Engineers must ensure thermal design accommodates this PD limit to avoid junction temperature exceeding 175°C, especially in enclosed or high-ambient environments where the P6KE440A A0G is deployed.
How does the leakage current of P6KE440A A0G compare at its VWM rating?
At its maximum stand-off voltage (VWM = 376 V), the P6KE440A A0G exhibits a maximum reverse leakage current (ID) of 1 μA at 25°C - verified per electrical specifications table. This ultra-low leakage ensures minimal power loss in high-impedance bias networks and preserves accuracy in precision sensing circuits upstream of the P6KE440A A0G. Leakage remains well below 10 μA even at elevated temperatures up to 125°C, supporting reliable operation in thermally demanding applications.
What package type and marking convention does P6KE440A A0G use?
P6KE440A A0G uses the DO-204AC (DO-15) axial leaded package with cathode band marking on one end. Per Taiwan Semiconductor's marking diagram, the device is laser-marked with part-specific code (e.g., "440A"), green compound indicator "G", date code "YWW", and factory code "F". The cathode band identifies the high-side terminal - essential for correct orientation during placement in unidirectional surge protection circuits using the P6KE440A A0G.
