Product details
Overview
P6KE110A-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 94.0V reverse standoff voltage (VRWM), 105.0V minimum breakdown voltage (VBR), 152.0V maximum clamping voltage (VC) at 4.0A peak pulse current (IPP), and DO-15 package with glass-passivated junction-used in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE110A-T datasheet, P6KE110A-T pinout, P6KE110A-T application, or P6KE110A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, 1.0ms pulse power derating above +25°C ambient, unidirectional polarity marking (cathode band), and compatibility with lead-free reflow profiles per J-STD-020 Level 1.
Technical Context
The P6KE110A-T operates as a silicon avalanche diode that enters controlled breakdown when transient voltage exceeds its VRWM, diverting surge current away from downstream circuitry. Its glass-passivated die ensures stable leakage performance and long-term reliability under repeated 8.3ms half-sine surges up to 100A IFSM.
Clamping behavior is defined by a 1.0ms 10/1000μs waveform per REA standards, with thermal resistance of 75°C/W (junction-to-ambient) and 15°C/W (junction-to-lead), enabling sustained operation at TL = +75°C with 5.0W steady-state dissipation on 40mm² copper land.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive surge-defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 94.0V-maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 105.0V min @ 1.0mA-guaranteed avalanche initiation threshold under test conditions |
| Clamping Voltage (VC) | 152.0V max @ 4.0A IPP-upper limit of protected node voltage during surge event |
| Package | DO-15 molded plastic (UL 94V-0)-standard axial-leaded through-hole package with 0.4g mass |
| Thermal Resistance (RθJA) | 75°C/W-determines junction temperature rise under static power dissipation |
| Moisture Sensitivity | Level 1 per J-STD-020-no floor life limitation or bake requirement prior to assembly |
Pinout & Package
DO-15 package: axial-leaded, cylindrical epoxy-molded case with cathode band marking for unidirectional polarity. Leads are tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected circuit ground | Current sink path during positive transients; tied to system GND or low-impedance return plane |
| Cathode | High-side connection to protected line (e.g., +12V rail) | Marked with band; connects to input/power trace requiring clamping to prevent overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Power | Enables robust protection against IEC 61000-4-5 Level 4 (4kV/2Ω) surges without degradation |
| Glass-Passivated Junction | Reduces surface leakage and improves long-term stability in humid or contaminated environments |
| Fast Response Time (<1.0ps) | Clamps transients before sensitive downstream ICs experience overstress-critical for microcontroller I/O protection |
| RoHS-Compliant Lead Finish | Meets EU Directive 2011/65/EU with full exemption documentation; compatible with Pb-free reflow profiles |
| Unidirectional Polarity | Prevents reverse-bias conduction during normal operation-essential for DC-biased power rail protection |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) Power Rail |
|---|---|
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 TVS clamp placed upstream of input filter capacitor and DC-DC converter. Use Value: Limits transient voltage to ≤152V, preventing damage to 200V-rated input capacitors and ensuring converter startup integrity after 100A surge events. | Use Scenario: +12V battery feed to BCM microcontroller and CAN transceiver in passenger vehicle door module. IC Role / Device Role / Timing Role: Unidirectional surge suppressor on main power rail, positioned before ESD protection diodes and LDO regulators. Use Value: Clamps load-dump transients (ISO 7637-2 Pulse 5a) to safe levels while maintaining <5μA leakage at 94V, preserving sleep-mode current budget. |
| Telecom AC-DC Adapter Secondary Side | Factory Automation Sensor Interface |
Use Scenario: Output side of isolated 48V telecom adapter subject to backfeed surges from connected equipment. IC Role / Device Role / Timing Role: Secondary-side TVS across output terminals to protect downstream PoE injectors and Ethernet PHYs. Use Value: Absorbs 600W pulses without failure, ensuring continuity of 48V power delivery during field-induced transients in data center environments. | Use Scenario: 24V analog sensor bus in CNC machine tool cabinet with long cable runs susceptible to EFT bursts. IC Role / Device Role / Timing Role: Point-of-entry TVS on sensor power line, mounted directly at connector PCB footprint. Use Value: Maintains ≤152V clamping during 5kHz EFT bursts (IEC 61000-4-4), preventing latch-up in 24V op-amp signal conditioning circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-T | Same VRWM (94V) and VC (152V), but SMC package (surface-mount); 600W rating maintained | Requires PCB redesign for SMD placement; better thermal performance due to lower RθJA (50°C/W) | Select for space-constrained designs where automated assembly and higher board density are prioritized |
| P6SMB110A-T | Identical electrical specs and DO-214AA package; same 600W rating and unidirectional configuration | DO-214AA has shorter leads and smaller footprint than DO-15; not suitable for high-vibration through-hole mounting | Select when transitioning from axial to flat-lead SMD layout while retaining mechanical robustness and surge handling |
Compared with SMBJ110A-T and P6SMB110A-T, the P6KE110A-T offers proven mechanical retention in high-shock environments via axial leads and simpler wave-solder compatibility-but requires more PCB area and exhibits higher thermal resistance than SMD alternatives.

FAQ
Is P6KE110A-T still in active production?
No-P6KE110A-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 supports last-time buy requirements for ongoing production programs.
What is the maximum operating temperature for P6KE110A-T?
The P6KE110A-T has an operating junction temperature range of –55°C to +175°C. At ambient temperatures above +25°C, its 600W peak pulse power must be derated linearly per Figure 4 in DS21502, reaching ~400W at +85°C ambient.
Can P6KE110A-T be used in bidirectional configurations?
No-P6KE110A-T is unidirectional only. The bidirectional variant is P6KE110CA-T, which lacks cathode band marking and exhibits symmetrical clamping in both polarities. Substitution requires schematic and layout revision to accommodate dual-rail protection topology.
How does P6KE110A-T compare to P6KE100A-T in clamping performance?
P6KE110A-T clamps at 152.0V max vs. P6KE100A-T's 137.0V max, reflecting its higher VRWM (94.0V vs. 85.5V). Both deliver identical 600W pulse power, but the 110A variant provides greater margin for systems with higher nominal rail voltages and tighter VDD tolerances.
