Product details
Overview
P6KE30A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 25.6V reverse standoff voltage (VRWM), 28.5V minimum breakdown voltage (VBR), 41.4V maximum clamping voltage (VC) at 14.4A peak pulse current, and DO-15 package with glass-passivated junction - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE30A-T datasheet, P6KE30A-T pinout, P6KE30A-T application, or P6KE30A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, peak pulse current handling under IEC 61000-4-5 surge conditions, thermal derating at elevated ambient temperatures, and unidirectional polarity alignment with DC rail topology.
Technical Context
This TVS operates as a voltage-clamped crowbar device triggered by transient overvoltage exceeding its breakdown threshold. Its glass-passivated silicon junction ensures stable avalanche characteristics and low leakage (<5 µA at VRWM), while the DO-15 package provides mechanical robustness and thermal path capability up to 5.0W steady-state dissipation at TL = +75°C.
The device responds within <1.0 ns to transients, clamping 10/1000 µs waveform surges to ≤41.4V at IPP = 14.4A. Its bidirectional counterpart (P6KE30CA-T) shares identical clamping and power ratings but supports AC-coupled or floating-line protection where polarity reversal may occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 1.0 ms non-repetitive surge without failure |
| Reverse Standoff Voltage | 25.6 V - maximum continuous DC operating voltage before leakage exceeds 5 µA |
| Breakdown Voltage | 28.5 V min @ 1.0 mA - guaranteed avalanche initiation threshold for reliable triggering |
| Clamping Voltage | 41.4 V max @ 14.4 A - limits downstream voltage stress during IEC 61000-4-5 Level 4 surge |
| Peak Pulse Current | 14.4 A - maximum transient current it can shunt while maintaining specified VC |
| Package | DO-15 - axial-leaded, UL 94V-0 molded plastic housing with 0.4 g mass and 75 °C/W θJA |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon die in molded plastic body (UL 94V-0), cathode band marking on unidirectional variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; defines reference for unidirectional clamping |
| Cathode | High-side connection point | Connected to protected line; conducts avalanche current when VR > VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables compliance with IEC 61000-4-5 surge immunity up to 4 kV (open-circuit) |
| Glass-passivated junction | Ensures stable VBR tolerance (±5%) and low parameter drift over temperature and life |
| Fast response time <1 ns | Protects sensitive logic and analog inputs before transient energy couples into IC pins |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A-T | Same VRWM (25.6V) and VC (41.4V), but SMC package (higher thermal mass, lower θJA ≈ 35 °C/W) | Better suited for high-power-density PCB layouts requiring higher steady-state power handling | Select when board space allows SMC footprint and thermal management includes copper pour or forced air |
| P6SMB30A-T | Identical electrical specs and DO-214AA package; same 600W rating but slightly higher VF in forward conduction | Compatible with automated placement systems using tape-and-reel; no axial lead forming required | Prefer for surface-mount assembly lines avoiding axial component insertion and trimming steps |
Compared with SMBJ30A-T and P6SMB30A-T, P6KE30A-T offers lowest cost per unit and proven reliability in through-hole industrial designs, though its DO-15 package requires manual or semi-automated insertion and delivers lower thermal performance than SMC/SMB packages under sustained surge duty cycles.

FAQ
Is P6KE30A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE30A-T and entire P6KE series (DS21502 Rev. 20–4, August 2024). Aetrix Electronics maintains limited legacy stock for ongoing production support and offers validated drop-in alternatives including SMBJ30A-T and P6SMB30A-T with identical electrical performance and enhanced thermal or assembly compatibility.
What is the maximum operating temperature for P6KE30A-T?
The P6KE30A-T is rated for junction and storage temperatures from –55°C to +175°C. Its steady-state power dissipation derates linearly above +75°C ambient (TL), reaching zero at +175°C. At +125°C ambient, allowable PD drops to approximately 2.5W based on the published derating curve in DS21502.
Can P6KE30A-T be used in bidirectional signal line protection?
No - P6KE30A-T is unidirectional only, with cathode band marking and asymmetric IV characteristics. For bidirectional AC or floating-line protection, use the designated P6KE30CA-T variant, which exhibits symmetrical clamping in both polarities and identical 41.4V VC rating at ±14.4A.
How does P6KE30A-T compare to SMAJ30A in surge handling?
P6KE30A-T and SMAJ30A share identical VRWM (25.6V), VBR (28.5V min), and VC (41.4V), but differ in package and power rating: SMAJ30A is rated for 400W (not 600W) and uses DO-214AC (SMA) package. Thus, P6KE30A-T handles 50% higher single-event surge energy, making it suitable for more severe IEC 61000-4-5 test levels where SMAJ30A would fail.
