Product details
Overview
P6KE36A-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 30.8V reverse standoff voltage (VRWM), 34.2V minimum breakdown voltage (VBR), 49.9V maximum clamping voltage (VC) at 12A peak pulse current, and DO-15 package with glass-passivated junction - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE36A-T datasheet, P6KE36A-T pinout, P6KE36A-T application, or P6KE36A-T equivalent, key selection criteria include clamping performance under 10/1000µs surge, thermal derating above +25°C ambient, unidirectional polarity marking, and compatibility with lead-free reflow profiles per J-STD-020 Level 1.
Technical Context
This TVS operates as a voltage-clamped crowbar device triggered by avalanche breakdown when transient voltage exceeds VBR. Its glass-passivated die ensures stable leakage (<5µA @ VRWM) and repeatable clamping across temperature (-55°C to +175°C).
The 600W peak pulse power rating applies to non-repetitive 1.0ms waveform (10/1000µs standard), with steady-state dissipation limited to 5.0W at TL = +75°C on 40mm² copper land. Thermal resistance from junction to ambient is 75°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 1.0ms 10/1000µs surge without failure |
| Reverse Standoff Voltage (VRWM) | 30.8V - maximum continuous DC operating voltage before leakage exceeds 5µA |
| Breakdown Voltage (VBR) | 34.2V min @ IT = 1.0mA - guaranteed avalanche initiation threshold |
| Clamping Voltage (VC) | 49.9V max @ IPP = 12.0A - limits protected circuit voltage during surge |
| Package | DO-15 - axial-leaded, molded plastic case rated UL 94V-0, 0.4g mass |
| Thermal Resistance (RθJA) | 75°C/W - defines junction-to-ambient temperature rise under steady-state bias |
| Operating Temperature | -55°C to +175°C - supports under-hood automotive and industrial environments |
Pinout & Package
DO-15 package: axial-leaded, cylindrical molded plastic body with cathode band marking. Leads are tin-plated, solderable per MIL-STD-202 Method 208. Dimensions: A = 25.40mm (length), B = 5.50–7.62mm (diameter), C = 0.686–0.889mm (lead diameter), D = 2.60–3.60mm (lead spacing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-potential node in unidirectional configuration |
| Cathode | High-side surge input terminal | Marked with band; accepts transient energy and clamps to VC when VRWM exceeded |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 24V systems |
| Glass-Passivated Junction | Ensures stable VBR tolerance (±5%) and low leakage drift over 1000-hour HTOL stress |
| RoHS-Compliant Lead Finish | Meets EU Directive 2011/65/EU with full exemption documentation; compatible with Pb-free reflow |
| Fast Response Time | Sub-nanosecond turn-on enables clamping before downstream IC damage in <100ns edge transients |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 24V DC input rail of programmable logic controller (PLC) power supply exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converter input. Use Value: Limits transient excursions to ≤49.9V, preventing MOSFET gate oxide rupture and enabling use of 60V-rated input capacitors. |
Use Scenario: LIN bus line and 12V auxiliary rail in BCM subjected to ISO 7637-2 Pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Unidirectional TVS on power input and data line, referenced to chassis ground. Use Value: Clamps 100V/500ms load dump to <50V within 1ns, preserving CAN/LIN transceiver integrity without adding series impedance. |
| Telecom Remote Radio Unit (RRU) | Smart Energy Meter Surge Protection |
Use Scenario: -48V DC feed line in outdoor RRU enclosure subject to lightning-induced surges via long cable runs. IC Role / Device Role / Timing Role: First-stage protector before DC-DC isolation stage and monitoring circuitry. Use Value: Absorbs 600W peak energy while maintaining VRWM margin >20% below -48V nominal, avoiding false triggering during brownouts. |
Use Scenario: AC mains input rectifier output and metering IC supply rail exposed to EN 61000-4-5 surges. IC Role / Device Role / Timing Role: Secondary clamping device after MOV-based front-end protection. Use Value: Provides precise low-clamping-voltage backup protection (VC = 49.9V) to safeguard 3.3V/5V metrology SoCs from residual overshoot. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-T | Same VRWM (36V) and VC (58.1V), but 600W in SMB package; lower RθJA (50°C/W) and higher IPP (10.3A) | Suitable for surface-mount layouts; requires PCB thermal relief for 5W steady-state dissipation | Select when board space is constrained and reflow assembly is preferred over axial through-hole |
| P6KE36CA-T | Bidirectional variant: identical VRWM/VBR/VC specs but symmetric clamping for AC-coupled lines | Required for RS-485, Ethernet PHY, or audio line protection where polarity reversal occurs | Choose only if bidirectional surge immunity is mandated; unidirectional P6KE36A-T offers tighter leakage (<5µA vs. 10µA) |
Compared with SMBJ36A-T, P6KE36A-T provides lower-profile axial mounting and superior moisture resistance (J-STD-020 Level 1), while P6KE36CA-T adds bidirectional capability at the cost of doubled reverse leakage - making P6KE36A-T optimal for cost-sensitive, high-reliability DC rail protection.

FAQ
Is P6KE36A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE36A-T (Document DS21502 Rev. 20-4 states "OBSOLETE – PART DISCONTINUED"). However, Aetrix Electronics maintains secured legacy inventory with full traceability and supports last-time-buy orders for ongoing production programs.
What is the meaning of the "-T" suffix in P6KE36A-T?
The "-T" suffix denotes tape-and-reel packaging: 4,000 units per 13-inch reel, optimized for automated SMT placement equipment. The base part P6KE36A is identical electrically and mechanically; only packaging differs from bulk or ammo-pack variants.
Can P6KE36A-T be used in place of P6KE36CA-T?
No - P6KE36A-T is unidirectional (cathode-banded), while P6KE36CA-T is bidirectional (no band, symmetrical clamping). Substitution risks open-circuit failure on negative transients or excessive leakage in AC-coupled applications; polarity and circuit topology must match exactly.
What is the maximum allowable lead temperature during soldering?
The DO-15 package supports a maximum lead temperature of +250°C for 10 seconds during manual soldering, per Diodes' packaging specification. For wave or reflow, follow J-STD-020 Level 1 profile: peak temperature ≤260°C, time above 217°C ≤60 seconds, with ramp rates ≤3°C/s.
