2M36ZH Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M36ZH is an active-status Zener diode rated for 36 V nominal voltage and 2 W maximum power dissipation in a DO-204AC (DO-15) axial through-hole package. This component is manufactured by Taiwan Semiconductor Corporation and is AEC-Q101 qualified for automotive applications. Substitute parts are identified based on matching electrical specifications and package compatibility to support design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M36ZH is determined by the following critical parameters:

1. Zener Voltage (Vz): Must match 36 V nominal with ±5% tolerance
2. Package Type: Must be DO-204AC or DO-15 axial through-hole configuration for mechanical and electrical compatibility
3. Reverse Leakage Current: Must not exceed 500 nA @ 27.4 V to maintain circuit performance
4. Voltage Tolerance: Must be ±5% to ensure specification compliance
5. RoHS Compliance: Must meet ROHS3 requirements for regulatory alignment
6. Operating Temperature Range: Must support the application's thermal environment

The 1N5365B-TP manufactured by Micro Commercial Co satisfies all substitution criteria. While this part features higher maximum power dissipation (5 W versus 2 W) and lower impedance (11 Ohms versus 25 Ohms), these represent performance enhancements that do not compromise circuit function. The matching zener voltage, tolerance, reverse leakage specification, package configuration, and compliance certifications establish full electrical and mechanical interchangeability.

Engineering Selection Recommendations

Primary Part (2M36ZH): Select this part when the application requires the full automotive-grade operating temperature range of -55°C to 175°C and when AEC-Q101 qualification is a mandatory requirement. This part is active-status with 1134 units in stock.

Substitute Part (1N5365B-TP): Select this part when supply constraints affect 2M36ZH availability or when the application operating temperature does not exceed 150°C. The 1N5365B-TP provides superior power handling (5 W) and lower impedance (11 Ohms), making it suitable for circuits where thermal margin or transient response is beneficial. This part is active-status with 3164 units in stock. Both parts maintain ROHS3 compliance and identical zener voltage and tolerance specifications.

Packaging Consideration: The 2M36ZH is supplied in Tape & Reel format, while the 1N5365B-TP is supplied in Cut Tape format. Verify packaging compatibility with assembly equipment and procurement workflows before selection.

Frequently Asked Questions (FAQ)

Q: Can the 1N5365B-TP directly replace the 2M36ZH in all applications?

A: The 1N5365B-TP is electrically and mechanically compatible with the 2M36ZH for circuits operating within the -55°C to 150°C temperature range. If the application requires operation above 150°C, the 2M36ZH must be used to maintain specification compliance.

Q: What is the significance of the different power ratings (2 W vs. 5 W)?

A: The 1N5365B-TP has a higher maximum power dissipation rating (5 W) compared to the 2M36ZH (2 W). This means the substitute part can safely dissipate more heat. In circuits designed for the 2M36ZH, the substitute will operate with additional thermal margin and will not cause circuit malfunction.

Q: Do the impedance differences affect circuit performance?

A: The 1N5365B-TP has lower impedance (11 Ohms) than the 2M36ZH (25 Ohms). Lower impedance generally improves transient response and voltage regulation characteristics. For circuits designed with the 2M36ZH impedance specification, the substitute will provide equal or improved performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2M36ZH and 1N5365B-TP are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths. Verify your assembly process compatibility before selecting based on packaging format.

Q: Is the 1N5365B-TP AEC-Q101 qualified?

A: The provided specifications do not include AEC-Q101 qualification status for the 1N5365B-TP. If automotive-grade qualification is a mandatory requirement, confirm qualification status with the manufacturer before substitution.
