Product details
Overview
P6KE24CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. 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 with glass-passivated junction-used in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE24CA-T datasheet, P6KE24CA-T pinout, P6KE24CA-T application, or P6KE24CA-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD rails, unidirectional vs. bidirectional polarity requirements, 1.0ms 600W pulse handling capability, and DO-15 thermal derating above +25°C ambient.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated die ensures stable breakdown characteristics and low leakage (<5µA @ VRWM), while fast response time (<1.0ps) limits voltage overshoot during ESD or lightning-induced transients.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity standards when properly laid out with minimal trace inductance. Thermal resistance from junction to ambient (RθJA = 75°C/W) mandates PCB copper land area design per Diodes' mounting guidelines to sustain steady-state dissipation up to 5.0W at TL = +75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive waveform-sustains single high-energy surges like ISO 7637-2 Pulse 1/2b in automotive systems. |
| Reverse Standoff Voltage | 20.5V-maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected circuit operating voltage. |
| Breakdown Voltage | 22.8V min @ 1.0mA-guaranteed conduction onset under transient stress, with ±5% tolerance confirmed per datasheet Table. |
| Clamping Voltage | 33.2V max @ 18A IPP-defines worst-case voltage seen by downstream ICs during full-rated surge event. |
| Package | DO-15-standard axial-leaded through-hole package with 9.5mm lead length, UL 94V-0 molded plastic housing. |
| Operating Temp | -55°C to +175°C-supports under-hood automotive and industrial environments without derating loss. |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, molded plastic body (UL 94V-0), 0.4g weight, moisture sensitivity level 1. Bidirectional marking shows type number only (no cathode band).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going transients; symmetrical with cathode for bidirectional operation. |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going transients; identical electrical behavior to anode due to bidirectional construction. |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables robust protection against IEC 61000-4-5 Level 4 (4kV line-to-line) surges without failure. |
| Glass-passivated die | Ensures long-term stability of VBR and low parametric drift over temperature and lifetime. |
| Bidirectional configuration | Eliminates need for polarity-aware layout-ideal for AC signal lines, RS-485, CAN, and sensor bridges. |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation; compatible with Pb-free reflow and wave soldering. |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24V DC input stage of PLC I/O module exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converter input, absorbing energy before it reaches sensitive regulation circuitry. Use Value: Limits transient voltage to ≤33.2V, preventing damage to 36V-rated input capacitors and MOSFET gate oxides. | Use Scenario: LIN bus transceiver power rail in door module subjected to battery clamp events and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional shunt protector on VBAT supply, clamping both positive spikes and negative rebound transients. Use Value: Maintains LIN transceiver operation during 12V system surges up to 33.2V, avoiding bus lockup or reset. |
| RS-485 Data Line Protection | Smart Meter AC Mains Interface |
Use Scenario: Differential pair termination on industrial RS-485 node installed in electrically noisy factory floor environment. IC Role / Device Role / Timing Role: Common-mode TVS across A/B lines referenced to ground, suppressing EFT bursts and induced surges. Use Value: Clamps common-mode transients to <33.2V while preserving signal integrity via low capacitance (<100pF @ 0V). | Use Scenario: Auxiliary 24V DC supply derived from rectified AC mains in utility smart meter with surge immunity requirement. IC Role / Device Role / Timing Role: Secondary-stage TVS after MOV and fuse, providing precise clamping where MOV let-through voltage exceeds IC rating. Use Value: Reduces residual clamping voltage from ~150V (MOV-only) to 33.2V, protecting isolated DC-DC controller ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | Same VRWM (20.5V) and VC (33.2V), but 600W rating in SMB package (surface-mount); RθJA = 50°C/W vs. 75°C/W. | Requires PCB real estate optimization for SMT assembly; better thermal performance in compact layouts. | Select when board space is constrained and reflow-compatible assembly is preferred over through-hole. |
| 1.5KE24CA | Same DO-15 package and bidirectional function, but 1500W peak power (1.5kW) and higher VC (36.0V @ 41.7A). | Higher energy absorption for severe surge environments (e.g., outdoor telecom), but larger voltage overshoot during clamping. | Select when system-level surge test levels exceed IEC 61000-4-5 Level 4 and clamping margin allows 36.0V. |
Compared with SMBJ24CA and 1.5KE24CA, P6KE24CA-T offers optimal balance of proven through-hole reliability, moderate surge capacity, and tight clamping for cost-sensitive industrial and automotive auxiliary circuits where DO-15 mechanical robustness and legacy compatibility are prioritized.

FAQ
Is P6KE24CA-T still in active production?
No-P6KE24CA-T is officially obsolete and discontinued per Diodes' DS21502 Rev. 20-4 (August 2024). Aetrix Electronics maintains limited legacy stock for design continuity and last-time buy support, but no new manufacturing runs are planned. Customers should evaluate SMBJ24CA or 1.5KE24CA for new designs.
What is the maximum allowable PCB trace length between P6KE24CA-T and protected IC?
Trace inductance must be minimized to preserve clamping effectiveness. For 18A peak current and sub-1ns response, total loop inductance should remain below 10nH-achievable with ≤5mm trace length, direct grounding to large copper pour, and placement within 3mm of the protected IC's power pin. Longer traces increase overshoot beyond 33.2V.
Can P6KE24CA-T replace unidirectional P6KE24A-T in a circuit?
Only if bidirectional protection is acceptable and circuit topology supports symmetrical clamping. P6KE24CA-T has identical VRWM, VBR, and VC specs but conducts on both polarities-unlike P6KE24A-T, which blocks reverse current. Replacing unidirectional with bidirectional may cause unintended conduction in DC-biased signal paths.
Does P6KE24CA-T meet AEC-Q200 stress testing requirements?
No-P6KE24CA-T is not AEC-Q200 qualified. While Diodes offers AEC-Q200–qualified TVS devices (e.g., D3SBxx series), this part lacks PPAP documentation, IATF 16949 manufacturing certification, and automotive-grade change control. Use only in non-safety-critical industrial or consumer applications unless validated per customer-specific qualification.
