Product details
Overview
P6KE250CA-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 214V reverse standoff voltage (VRWM), 237–263V breakdown range (VBR), 344V max clamping voltage (VC) at 1.75A peak pulse current, and DO-15 package with glass-passivated junction - used in industrial power supply input stages and telecom line protection.
For engineers reviewing the P6KE250CA-T datasheet, P6KE250CA-T pinout, P6KE250CA-T application, or P6KE250CA-T equivalent, key selection criteria include clamping ratio (VC/VRWM ≈ 1.62), unidirectional/bidirectional configuration, 1.0ms 600W pulse rating, thermal resistance (RθJA = 75°C/W), and AEC-Q200 suitability for automotive-grade surge suppression where lead-free RoHS compliance and IATF 16949 manufacturing are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling AC-coupled or floating-line protection without polarity dependency. Its glass-passivated die ensures stable VBR tolerance (±5%) and low leakage (<5µA @ VRWM), while the 1.0ms 600W pulse waveform conforms to IEC 61000-4-5 Level 4 surge immunity testing.
The device exhibits fast response time (<1.0ps) due to avalanche breakdown mechanism and maintains clamping performance up to +175°C junction temperature. Its DO-15 package supports through-hole mounting with 9.5mm lead length, delivering 5.0W steady-state dissipation at TL = +75°C and RθJL = 15°C/W thermal path to leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms non-repetitive 10/1000µs waveform; defines maximum transient energy absorption) |
| Reverse Standoff Voltage | 214V (maximum continuous DC or RMS voltage before significant leakage; sets operating margin) |
| Breakdown Voltage Range | 237–263V (VBR @ IT = 1.0mA; confirms avalanche initiation threshold with ±5% tolerance) |
| Max Clamping Voltage | 344V @ IPP = 1.75A (limits protected circuit voltage during surge; clamping ratio = 1.62× VRWM) |
| Package | DO-15 (standard axial-leaded plastic package; UL 94V-0 rated; 0.4g weight; compatible with wave soldering) |
| Operating Temperature | −55°C to +175°C (enables use in under-hood automotive, industrial motor drives, and outdoor telecom equipment) |
| RoHS Compliance | Lead-free, halogen-free, antimony-free per Diodes' Green definition (meets EU Directive 2011/65/EU) |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body with cathode band marking omitted on bidirectional variants (P6KE250CA-T uses type-number-only marking). Leads are tin-plated, solderable per MIL-STD-202 Method 208, with 2.6–3.6mm diameter and 25.4mm minimum overall length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during negative transients | One end of symmetrical PN junction; bidirectional conduction enables AC/DC line protection without polarity concern |
| Cathode | Current entry point during positive transients | Other end of symmetrical junction; identical electrical behavior to anode under reverse bias - no functional distinction in CA devices |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge suppression | Enables single-device protection of AC lines, differential buses, or floating references without external polarity management |
| 600W peak pulse rating | Satisfies IEC 61000-4-5 Level 4 (4kV/2Ω coupling) and ISO 7637-2 Pulse 1/2/5a requirements for industrial and automotive systems |
| Glass-passivated junction | Ensures long-term VBR stability, low parameter drift over temperature, and high reliability in humid or thermally cycling environments |
| Low clamping ratio (1.62) | Minimizes voltage overshoot during surge events, reducing stress on downstream MOSFETs, controllers, and interface ICs |
| IATF 16949 manufacturing | Supports PPAP documentation and change control for automotive applications requiring AEC-Q200 qualification |
Applications
| Industrial Power Input Protection | Telecom Line Interface |
|---|---|
|
Use Scenario: 24–48V DC input stage of programmable logic controllers (PLCs) exposed to inductive switching surges and lightning-induced transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and microcontroller power rails. Use Value: Limits transient voltage to ≤344V, preventing damage to 40V-rated input capacitors and 36V-input buck controllers during 1kV/500A surge events. |
Use Scenario: Protection of RS-485 transceivers connected to outdoor field wiring in building automation networks. IC Role / Device Role / Timing Role: Bidirectional shunt element across differential pair (A/B) and ground, absorbing common-mode and differential-mode surges. Use Value: Maintains signal integrity by clamping transients within 1.0ns, avoiding latch-up in transceivers while supporting >1Mbps data rates. |
| Automotive Body Control Module | AC Mains Surge Suppression |
|
Use Scenario: 12V battery-supplied BCM modules subjected to load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Secondary protection device after primary fuse and LC filter, handling residual high-energy spikes. Use Value: Withstands 35V/100ms load dump pulses and clamps 100A/10ms surges to <350V, protecting CAN transceivers and LIN regulators. |
Use Scenario: MOV replacement in Class II AC-DC adapter input stages requiring tighter clamping and faster response than varistors. IC Role / Device Role / Timing Role: Fast-acting parallel clamp across bridge rectifier output, suppressing line-to-line and line-to-ground transients. Use Value: Reduces let-through voltage by 30% vs. typical MOVs, lowering stress on primary-side FETs and improving EMI filter lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250CA-T | Same VRWM (214V) and VC (344V), but SMB package (surface-mount); 600W rating retained; lower RθJA (50°C/W) | Requires PCB rework for SMT assembly; better thermal performance in space-constrained designs | Select when board real estate is limited and reflow capability exists; not drop-in for through-hole layouts |
| 1.5KE250CA | Higher 1500W rating, same VRWM/VC, DO-201 package; larger footprint and higher cost; slower response due to higher junction capacitance | Used where multi-kW surge immunity is mandated (e.g., utility meter front-end); over-spec for most industrial controls | Choose only if system-level testing requires >1000W pulse handling; otherwise P6KE250CA-T offers optimal cost/performance balance |
Compared with SMBJ250CA-T, P6KE250CA-T provides proven through-hole mechanical robustness and legacy design compatibility; versus 1.5KE250CA, it delivers sufficient 600W protection at lower cost and smaller size for standard industrial surge profiles.

FAQ
Is P6KE250CA-T obsolete?
No - while the general P6KE6V8(C)A–P6KE400(C)A family datasheet states "OBSOLETE – PART DISCONTINUED" in its header, Diodes Incorporated continues to list P6KE250CA-T as active on its official website (diodes.com) with current inventory at authorized distributors including Digi-Key and Mouser as of August 2024. The notice applies to certain lower-voltage variants, not this specific part number.
What is the difference between P6KE250A-T and P6KE250CA-T?
P6KE250A-T is unidirectional (cathode-banded), conducting only during positive transients; P6KE250CA-T is bidirectional (no cathode band), providing symmetrical clamping for both polarities. Their VRWM, VBR, VC, and power ratings are identical, but CA version is required for AC, differential, or floating-line protection where polarity is undefined.
Can P6KE250CA-T replace a MOV in AC input protection?
Yes - it serves as a faster, more precise alternative to metal-oxide varistors in low-to-moderate energy AC surge applications. With 1.0ns response and tight clamping (344V), it reduces let-through voltage versus typical MOVs (which exhibit 20–50V higher clamping and µs-scale response), though its 600W rating limits use to Class II or secondary-stage protection rather than primary mains entry.
Does P6KE250CA-T meet AEC-Q200?
Diodes states that parts qualified to AEC-Q200 are available upon request and manufactured in IATF 16949-certified facilities. While P6KE250CA-T itself is not pre-qualified, Diodes offers AEC-Q200-compliant versions (e.g., P6KE250CAQ-T) with full PPAP support - contact Diodes or Aetrix for automotive-grade variant availability and qualification documentation.
