Product details
Overview
P6KE30CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode in DO-15 package, 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 (IPP), and operates across –55°C to +175°C.
For engineers reviewing the P6KE30CA-T datasheet, P6KE30CA-T pinout, P6KE30CA-T application, or P6KE30CA-T equivalent, this component serves as a robust, RoHS-compliant surge protector for automotive power supplies, industrial I/O interfaces, telecom line cards, and AC/DC adapter inputs where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.45), and 600W pulse handling are required.
Technical Context
The P6KE30CA-T is a glass-passivated, bidirectional avalanche diode optimized for unidirectional or bidirectional transient suppression per IEC 61000-4-2/4-4/4-5. Its clamping behavior is defined by a controlled avalanche breakdown with <1 ns response time and stable thermal performance up to TJ = +175°C.
It delivers 600W peak pulse power (tP = 1.0 ms, 10/1000 µs waveform), supports 100A non-repetitive forward surge current (8.3 ms half-sine), and maintains ≤5.0 µA reverse leakage at VRWM - critical for low-power standby circuits and battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single-event surges up to 1.0 ms without failure, enabling compliance with Level 4 IEC 61000-4-5 (4 kV line-to-line) |
| Reverse Standoff Voltage (VRWM) | 25.6 V - maximum continuous DC or RMS voltage before significant leakage; sets operating margin for 24V nominal systems |
| Breakdown Voltage (VBR) | 28.5 V min @ 1.0 mA - ensures reliable avalanche initiation above normal operating voltage, minimizing false triggering |
| Clamping Voltage (VC) | 41.4 V max @ 14.4 A - limits protected circuit voltage during surge, providing ~1.45× VBR clamping ratio for predictable stress control |
| Operating Temperature | –55°C to +175°C - supports under-hood automotive, industrial motor drives, and high-ambient power supply designs |
| Package | DO-15 - industry-standard axial leaded package with 0.4 g mass, UL 94V-0 molding, and 9.5 mm lead length for 5.0 W steady-state dissipation |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), cathode band not marked on bidirectional version; marking consists of "P6KE30CA" only. Leads are plated, solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink (bidirectional) | Conducts surge current in either polarity; symmetric structure enables identical clamping in both directions |
| Cathode | Transient current sink (bidirectional) | Functionally identical to Anode in bidirectional configuration; no polarity dependence in circuit layout |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables protection against severe transients (e.g., ISO 7637-2 Pulse 1/2a/5a) without derating in compact DO-15 footprint |
| Glass-passivated junction | Improves long-term reliability and moisture resistance vs. epoxy-passivated alternatives; qualified for automotive-grade humidity testing |
| Bidirectional architecture | Eliminates need for polarity-aware placement in AC-coupled or floating signal paths (e.g., RS-485, CAN bus, sensor bridges) |
| RoHS-compliant, lead-free finish | Meets EU Directive 2011/65/EU with full exemption documentation; compatible with standard SnPb and lead-free reflow profiles |
Applications
| Automotive Power Distribution | Industrial PLC I/O Protection |
|---|---|
Use Scenario: 24V battery rail in engine control units exposed to load dump (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping device placed upstream of DC/DC converters and microcontroller power inputs. Use Value: Clamps transients to ≤41.4V, preventing damage to 36V-rated input stages while surviving 100A surge pulses. | Use Scenario: Analog input channels (0–10 V, 4–20 mA) on programmable logic controllers subject to field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: First-line protection element mounted directly at terminal block entry point. Use Value: Responds in <1 ns to clamp fast transients, limiting voltage excursion to safe levels for precision op-amps and ADC front-ends. |
| Telecom Line Interface | AC/DC Adapter Input Stage |
Use Scenario: T1/E1 line drivers and receivers interfacing with outside plant wiring susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential pair prior to transformer coupling. Use Value: Symmetric clamping preserves signal integrity during common-mode surges while meeting GR-1089-CORE Level 3 requirements. | Use Scenario: Input rectifier stage of offline SMPS in consumer adapters, exposed to AC mains surges (IEC 61000-4-5). IC Role / Device Role / Timing Role: Secondary surge limiter after MOV, absorbing residual energy and reducing let-through voltage. Use Value: Low clamping voltage (41.4 V) prevents overstress on bridge rectifier and bulk capacitor during 4 kV combination wave tests. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | Surface-mount SMB package; 33V VRWM; 53.3V VC @ 11.3A; lower thermal resistance (RθJA = 50°C/W) | Preferred for automated SMT assembly; limited to ≤150°C ambient due to smaller thermal mass | Select when board space is constrained and reflow compatibility is required; verify PCB copper area for thermal management. |
| 1.5KE33CA | Higher 1500W peak power; same DO-15 package; 33V VRWM; 53.3V VC @ 28.3A; larger die size increases capacitance (~150 pF) | Better suited for high-energy surges (e.g., utility meter surge immunity); higher clamping voltage reduces system margin | Choose when legacy DO-15 footprint must be retained but surge energy exceeds 600W capability. |
Compared with SMBJ33CA and 1.5KE33CA, P6KE30CA-T offers optimal balance of axial-lead manufacturability, 600W surge handling, and tight 41.4V clamping for 24V systems - making it ideal for cost-sensitive, through-hole industrial and automotive modules where thermal derating and manual assembly are acceptable.

FAQ
Is P6KE30CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE30CA-T (DS21502 Rev. 20-4, August 2024). However, Aetrix Electronics maintains legacy inventory and supports continued supply through authorized channel partners and last-time-buy programs for existing designs.
What is the difference between P6KE30A-T and P6KE30CA-T?
P6KE30A-T is unidirectional (cathode-banded), while P6KE30CA-T is bidirectional (no cathode band, marked "P6KE30CA"). Their electrical specs are identical except for polarity behavior: the 'C' suffix indicates symmetrical clamping in both directions, essential for AC or floating signal paths.
Can P6KE30CA-T replace P6KE33CA-T in a 24V system?
Yes, with design verification: P6KE30CA-T's 25.6V VRWM provides tighter margin below 24V nominal rails than P6KE33CA-T's 28.2V VRWM, reducing risk of leakage or premature conduction. Its lower clamping voltage (41.4V vs. 45.7V) also improves downstream component safety - confirm thermal derating at end-equipment ambient temperatures.
Does P6KE30CA-T meet AEC-Q200 requirements?
While not explicitly AEC-Q200 qualified, P6KE30CA-T is manufactured in IATF 16949-certified facilities and supports automotive change control (PPAP-capable). Diodes recommends contacting their automotive team for qualification path or approved alternatives like the AEC-Q200-compliant D3V3M12-7.
