P6KE36A-T Equivalent & Substitute Parts

Part Overview

The P6KE36A-T is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection applications. This unidirectional zener diode operates with a 30.8V reverse standoff voltage and provides 49.9V clamping at peak pulse current. The part is packaged in DO-15 (DO-204AC) axial configuration for through-hole mounting.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement): P6KE36A-AP, P6KE36A-BP, and P6KE36A-TP from Micro Commercial Co are direct electrical and mechanical equivalents. All three maintain identical voltage specifications (30.8V standoff, 49.9V clamping) and 12A peak pulse current. These parts are active products with full RoHS3 compliance and REACH unaffected status. Selection among these three depends on packaging requirements: -AP (Bulk), -BP (Bulk), or -TP (Cut Tape).

Secondary Substitutes (Compatible Electrical Performance): P6KE36A from Fairchild Semiconductor and P6KE36A-HF from Comchip Technology maintain identical voltage and power specifications. The Fairchild part offers slightly higher peak pulse current (12.6A) and is active. The Comchip part provides 12.02A current with RoHS3 compliance. Both are suitable where the original DO-15 package is required.

Alternative Voltage Class (Limited Compatibility): BZW06-31RL from STMicroelectronics shares the same 30.8V reverse standoff voltage but features higher clamping voltage (64.3V) and significantly higher peak pulse current (62A at 8/20µs). This part is suitable only for applications where higher clamping voltage and current handling are acceptable or beneficial.

Axial Package Option: P6KE36AE3/TR13 from Microsemi Corporation provides identical electrical specifications in axial through-hole configuration. This part extends the operating temperature range to -65°C minimum and is suitable for applications requiring axial lead geometry.

Frequently Asked Questions (FAQ)

Q: Can P6KE36A-AP, P6KE36A-BP, and P6KE36A-TP be used interchangeably with P6KE36A-T?

A: Yes. All three Micro Commercial Co variants maintain identical electrical specifications: 30.8V reverse standoff, 49.9V clamping voltage, and 12A peak pulse current. The differences are packaging formats (Bulk, Bulk, and Cut Tape respectively). Selection depends on your procurement and assembly requirements.

Q: What is the difference between P6KE36A from Fairchild and the Micro Commercial variants?

A: The Fairchild P6KE36A provides slightly higher peak pulse current (12.6A versus 12A) while maintaining all other electrical parameters. Both are active products. The Fairchild part operates at -50°C minimum versus -55°C for the Micro Commercial parts.

Q: Is BZW06-31RL a suitable replacement?

A: BZW06-31RL shares the same 30.8V reverse standoff voltage but differs significantly in clamping voltage (64.3V versus 49.9V) and peak pulse current (62A versus 12A). This part is suitable only if your application can tolerate higher clamping voltage and benefits from increased current handling capability.

Q: What are the packaging differences among the substitute parts?

A: P6KE36A-AP and P6KE36A-BP are supplied in Bulk packaging. P6KE36A-TP is supplied in Cut Tape (CT). P6KE36A-HF is supplied in Tape & Box (TB). P6KE36AE3/TR13 uses axial lead geometry instead of DO-15. All maintain through-hole mounting compatibility except for lead configuration differences.

Q: Are all substitute parts RoHS3 compliant?

A: P6KE36A-T, P6KE36A-TP, P6KE36A-HF, and P6KE36AE3/TR13 are confirmed RoHS3 compliant. P6KE36A-AP and P6KE36A-BP are REACH unaffected. Verify specific compliance documentation for your application requirements.

Q: What is the operating temperature range consideration for substitution?

A: P6KE36A-T operates -55°C to 175°C. Micro Commercial variants match this range. Fairchild P6KE36A operates -50°C to 175°C (higher minimum). Comchip P6KE36A-HF and Microsemi P6KE36AE3/TR13 operate to 150°C maximum (lower maximum). Select based on your thermal environment requirements.
