Product details
Overview
P6KE10A-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 8.55V reverse standoff voltage (VRWM), 9.50V minimum breakdown voltage (VBR), 14.5V maximum clamping voltage (VC) at 41.0A peak pulse current, and DO-15 axial package - used in industrial power supplies, automotive body control modules, and PoE-powered devices.
For engineers reviewing the P6KE10A-T datasheet, P6KE10A-T pinout, P6KE10A-T application, or P6KE10A-T equivalent, key selection criteria include clamping ratio (VC/VBR ≈ 1.53), low leakage (<10µA @ VRWM), fast response time (<1.0ps), and compatibility with IEC 61000-4-2 Level 4 ESD protection requirements.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (>100MΩ), but avalanches within picoseconds when transient voltage exceeds VBR to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability across -55°C to +175°C operating range.
The device is rated for 600W non-repetitive peak pulse power (tp = 1.0ms, 10/1000µs waveform), supports 100A forward surge current (8.3ms half-sine), and exhibits thermal resistance of 75°C/W (junction-to-ambient) when mounted on standard PCB land patterns - enabling robust surge handling without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms 10/1000µs waveform; defines maximum transient energy absorption capability) |
| Reverse Standoff Voltage (VRWM) | 8.55V (maximum continuous DC or RMS voltage before significant leakage; sets operating rail margin) |
| Breakdown Voltage (VBR) | 9.50V min @ 1.0mA (avalanche initiation threshold; ensures reliable triggering above normal operating voltage) |
| Clamping Voltage (VC) | 14.5V max @ 41.0A IPP (voltage seen by protected circuit during worst-case surge; determines safe IC withstand level) |
| Peak Pulse Current (IPP) | 41.0A (maximum surge current the device can safely clamp; directly tied to system-level surge test compliance) |
| Leakage Current (IR) | <10µA @ 8.55V (ensures minimal standby power loss and no false triggering on nominal supply) |
| Package | DO-15 (axial leaded, 0.4g weight, UL 94V-0 molded plastic; compatible with wave soldering and manual assembly) |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, cathode indicated by band on body. Leads are tin-plated, solderable per MIL-STD-202 Method 208, with 9.5mm lead length for thermal derating calculations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path | Connected to ground or low-impedance reference; completes clamping loop during transient events |
| Cathode | Protected line input | Connected to line being protected (e.g., +12V rail); avalanche conduction occurs from cathode to anode |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Enables single-device protection against IEC 61000-4-5 4kV surge (line-earth) in 24V systems |
| Fast response time (<1.0ps) | Clamps transients before sensitive logic or analog circuitry sustains damage |
| Glass passivated die construction | Ensures stable VBR over temperature and lifetime; eliminates moisture-induced parameter drift |
| RoHS-compliant lead finish | Meets global environmental regulations without compromising solderability or thermal performance |
| Low clamping ratio (VC/VBR ≈ 1.53) | Minimizes voltage overshoot during clamping - critical for protecting 12V-rated ICs with 16V abs max ratings |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Primary shunt TVS placed between VIN and GND upstream of DC-DC converter input filter. Use Value: Clamps 100V/100ms load dump transients to ≤14.5V, preventing MOSFET gate oxide rupture and regulator latch-up. |
Use Scenario: LIN bus line protection in door module ECU subjected to battery reversal and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN data line and chassis ground. Use Value: Limits line voltage to 14.5V during 12V reverse polarity event, preserving transceiver ESD structures and bus integrity. |
| POE-Powered Access Point | Smart Meter Communication Interface |
|
Use Scenario: Ethernet port protection on IEEE 802.3af/at powered device (PD) receiving up to 57V DC via RJ45. IC Role / Device Role / Timing Role: TVS on PSE-side DC feed line (pair 4–5 or 7–8) before PD controller IC. Use Value: Absorbs 600W lightning-induced surges while maintaining <10µA leakage to avoid false PD detection. |
Use Scenario: RS-485 interface protection in utility smart meter exposed to induced surges on long outdoor runs. IC Role / Device Role / Timing Role: Bidirectional clamping (using P6KE10CA variant) across A/B differential pair to ground. Use Value: Maintains signal integrity below 14.5V clamping during 10/1000µs transients, preserving 250kbps communication timing margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VRWM (10V), lower PPK (400W), SMA package (surface-mount) | Requires PCB real estate optimization; unsuitable for through-hole legacy designs | Select when board space is constrained and reflow assembly is available |
| P6KE10CA | Bidirectional version; identical VRWM, VBR, VC, and IPP specs | Protects AC-coupled or bidirectional signal lines (e.g., RS-485, CAN) | Choose for symmetric surge threats where polarity reversal must be suppressed |
Compared with P6KE10A-T, SMAJ10A trades 33% lower surge capacity for SMT compatibility, while P6KE10CA retains identical clamping performance but enables bidirectional protection - making the original unidirectional DO-15 variant optimal for cost-sensitive, high-energy DC rail protection where polarity is fixed.

FAQ
Is P6KE10A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE10A-T (Document DS21502 Rev. 20-4 states "OBSOLETE – PART DISCONTINUED"). Aetrix Electronics maintains limited legacy stock and offers controlled allocation for ongoing production needs, with full traceability and documentation.
What is the difference between P6KE10A-T and P6KE10CA-T?
P6KE10A-T is unidirectional (cathode-banded), suppressing only positive transients relative to ground; P6KE10CA-T is bidirectional (no band), clamping both polarities equally. Their electrical specs (VRWM, VBR, VC, IPP) are identical, but CA variants are used on AC or differential lines like RS-485 or CAN.
Can P6KE10A-T replace P6KE12A-T in a 12V system?
No - P6KE10A-T has VRWM = 8.55V, which is too low for reliable operation on a nominal 12V rail (risk of leakage and thermal runaway). P6KE12A-T (VRWM = 10.2V) provides appropriate margin; substituting requires verifying that downstream components tolerate 14.5V clamping versus 16.7V.
What is the thermal derating behavior above +25°C ambient?
Per Figure 4 in DS21502, P6KE10A-T's peak pulse power derates linearly: at +75°C ambient, it delivers ~75% of rated 600W (450W); at +125°C, ~50% (300W). Steady-state power dissipation drops to 5.0W at TL = +75°C with 9.5mm leads on 40mm² copper land.
