P6KE36C Equivalent & Substitute Parts

Part Overview

The P6KE36C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in through-hole applications. This component operates with a reverse standoff voltage of 30.8V and provides 600W peak pulse power dissipation in a DO-15 axial package. The P6KE36C is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6KE36C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 30.8V
• Voltage - Clamping (Max) @ Ipp: Maximum 52.4V
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Package / Case: DO-15 Axial
• Mounting Type: Through Hole
• Type: Zener

Substitute parts must maintain identical reverse standoff voltage (30.8V), equivalent or lower clamping voltage, and the same 600W power rating. All candidates must be bidirectional single-channel devices in DO-15 through-hole packages. The P6KE36CA (Taiwan Semiconductor Corporation) and P6KE36CA-G (Comchip Technology) meet these electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both P6KE36CA and P6KE36CA-G are active, production-supported alternatives to the obsolete P6KE36C. The P6KE36CA (Taiwan Semiconductor Corporation) offers the highest inventory availability at 25,300 units and maintains ROHS3 compliance with REACH unaffected status. The P6KE36CA-G (Comchip Technology) provides an alternative with 914 units in stock, packaged in Tape & Box format, and supports an operating temperature range of -55°C to 150°C.

Both substitutes deliver superior clamping voltage performance (49.9V versus 52.4V) and specified peak pulse current ratings (12A and 12.02A respectively), providing enhanced protection characteristics within the same electrical class and package footprint.

Frequently Asked Questions (FAQ)

Q: Can P6KE36CA be used as a direct replacement for P6KE36C?

A: Yes. Both devices share identical reverse standoff voltage (30.8V), equivalent 600W power rating, and DO-15 through-hole packaging. The P6KE36CA delivers lower clamping voltage (49.9V vs. 52.4V), which provides improved transient suppression performance.

Q: What is the difference between P6KE36CA and P6KE36CA-G?

A: Both parts are electrically equivalent with 30.8V standoff voltage and 49.9V clamping voltage. The primary differences are manufacturer (Taiwan Semiconductor vs. Comchip Technology), packaging format (standard vs. Tape & Box), inventory availability, and operating temperature range (-55°C to 175°C vs. -55°C to 150°C).

Q: Are all substitute parts RoHS compliant?

A: Yes. P6KE36C, P6KE36CA, and P6KE36CA-G are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Why does the P6KE36CA have a lower clamping voltage than the original P6KE36C?

A: The clamping voltage difference (49.9V vs. 52.4V) reflects manufacturing variations within the P6KE36 series specification. Both values fall within acceptable design margins for general-purpose transient suppression applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the lower clamping voltage of the substitute parts. The 49.9V maximum clamping voltage of P6KE36CA and P6KE36CA-G is within typical design tolerances for 30.8V standoff applications.
