Product details
Overview
P6KE24A-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 20.5V reverse standoff voltage (VRWM), 22.8V minimum breakdown voltage (VBR), 33.2V maximum clamping voltage (VC) at 18A peak pulse current, and DO-15 package construction for through-hole mounting in industrial power supplies and automotive body electronics.
For engineers reviewing the P6KE24A-T datasheet, P6KE24A-T pinout, P6KE24A-T application, or P6KE24A-T equivalent, this part supports fast-response surge suppression in 24V system interfaces where clamping performance, thermal robustness, and RoHS-compliant lead-free finish are critical selection criteria.
Technical Context
The P6KE24A-T operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to ESD and lightning-induced transients. Its unidirectional configuration enables asymmetric clamping-blocking reverse conduction while clamping positive surges above VBR.
Thermal design relies on its DO-15 package's 75°C/W junction-to-ambient thermal resistance and 5.0W steady-state power dissipation at TL = +75°C. Derating curves confirm usable pulse energy down to -55°C and up to +175°C operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms 10/1000µs waveform; defines maximum single-event surge energy handling) |
| Reverse Standoff Voltage (VRWM) | 20.5V (maximum continuous DC or RMS voltage before significant leakage; sets operating rail margin) |
| Breakdown Voltage (VBR) | 22.8V min @ 1.0mA (avalanche initiation threshold; ensures reliable turn-on before damage to downstream ICs) |
| Clamping Voltage (VC) | 33.2V max @ 18A IPP (voltage seen by protected circuit during worst-case surge; determines safe IC survival margin) |
| Peak Pulse Current (IPP) | 18.0A (maximum non-repetitive surge current it can shunt without failure; correlates directly to IEC 61000-4-5 Level 4 immunity) |
| Package | DO-15 (standard axial-leaded through-hole package; enables manual assembly and high-reliability solder joints on PCBs) |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), cathode band marking on unidirectional devices. Leads are tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to ground or low-side reference; completes clamping path when transient exceeds VRWM |
| Cathode | Current exit terminal during reverse-biased clamping | Connected to protected line; conducts avalanche current to ground during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Supports IEC 61000-4-5 4th edition surge testing (1.2/50μs–8/20μs combination wave) on 24V DC inputs |
| Glass-passivated die construction | Ensures stable VBR over time and temperature; eliminates moisture-induced parameter drift in humid environments |
| Fast response time (<1.0ns) | Clamps transients before sensitive logic or analog circuitry sustains damage; critical for CAN/LIN bus protection |
| RoHS-compliant lead-free finish | Meets global environmental compliance requirements without compromising solder wetting or joint reliability |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) Inputs |
|---|---|
Use Scenario: 24V DC input stage of DIN-rail mounted PLC power supply exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp protecting upstream rectifier and downstream DC-DC controller ICs. Use Value: Limits transient voltage to ≤33.2V during 18A surges, preserving 36V-rated input capacitors and enabling use of cost-optimized 40V MOSFETs. |
Use Scenario: LIN bus line interface in door module subjected to battery reversal and ESD events per ISO 10605. IC Role / Device Role / Timing Role: Unidirectional TVS placed between LIN transceiver pin and vehicle battery rail. Use Value: Clamps negative transients to ground while blocking reverse battery connection; maintains LIN signal integrity below 1V offset. |
| Telecom Remote Radio Unit (RRU) DC Feeder | Factory Automation Sensor Interface |
Use Scenario: 24V DC power feed to outdoor 5G RRU unit vulnerable to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: First-stage surge protector on DC input before DC-DC conversion and RF front-end biasing. Use Value: Absorbs 600W pulses without degradation, reducing need for secondary MOV-based protection and minimizing board space. |
Use Scenario: Analog 4–20mA current loop input on programmable logic controller (PLC) analog input card. IC Role / Device Role / Timing Role: Line-to-ground TVS on each channel to prevent field-wiring induced transients from damaging precision op-amps and ADCs. Use Value: Maintains <5µA leakage at 20.5V, avoiding measurement error; clamps to 33.2V before 24-bit delta-sigma ADC input stages saturate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A-T | Same VRWM/VBR/VC specs but SMB package (surface-mount); 600W rating retained; lower RθJA (50°C/W vs 75°C/W) | Better suited for automated SMT production and space-constrained layouts; less suitable for manual repair or high-vibration environments | Select when board assembly uses reflow only and thermal management includes copper pour under pad |
| P6KE24CA-T | Bidirectional version; identical VRWM/VBR/VC values but symmetrical clamping for AC or dual-polarity signals | Required for RS-485 differential pairs or AC-coupled sensor outputs where polarity reversal occurs | Choose only if protected line may experience both positive and negative transients relative to ground |
Compared with P6KE24A-T, SMBJ24A-T offers superior thermal performance and SMT compatibility but reduced mechanical robustness, while P6KE24CA-T provides bidirectional clamping essential for AC signal paths-neither is pin-compatible, and substitution requires layout and schematic revision.

FAQ
Is P6KE24A-T still in active production?
No-P6KE24A-T is officially obsolete per Diodes Incorporated's DS21502 Rev. 20-4 (August 2024). However, Aetrix Electronics maintains secured legacy inventory with full traceability and documentation for ongoing production support of mature designs.
What is the maximum operating temperature for P6KE24A-T?
The P6KE24A-T has an operating and storage temperature range of -55°C to +175°C. Its thermal resistance values (RθJA = 75°C/W, RθJC = 20°C/W) allow sustained operation at +125°C ambient when mounted on adequate copper land area per datasheet guidelines.
Can P6KE24A-T be used in bidirectional signal lines like RS-485?
No-P6KE24A-T is unidirectional and will not clamp negative transients. For RS-485 or other AC-coupled or polarity-agnostic lines, the bidirectional P6KE24CA-T must be used instead to ensure symmetrical clamping above and below ground.
How does P6KE24A-T compare to MOV-based protection?
P6KE24A-T offers faster response (<1ns vs >25ns for MOVs), tighter voltage tolerance (±5% VBR vs ±20% for MOVs), and no degradation after repeated surges-making it preferable for precision 24V systems where clamping accuracy and longevity are critical.
