ZMC11 Equivalent & Substitute Parts

Part Overview

The ZMC11 is an 11 V Zener diode manufactured by Diotec Semiconductor, rated for 500 mW power dissipation with ±5% voltage tolerance. This surface mount component is housed in a SOD-80C package (DO-213AC, MINI-MELF form factor) and operates across the temperature range of -50°C to 175°C. The ZMC11 maintains Active product status with 755 units currently in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative sources become necessary due to inventory availability, packaging format requirements, or tolerance specifications for particular application demands.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ZMC11 are qualified based on matching the following critical parameters:

• Zener Voltage (Nominal): 11 V
• Maximum Power Dissipation: 500 mW
• Impedance (Maximum): 20 Ohms
• Reverse Leakage Current: 100 nA @ 8 V
• Operating Temperature Range: -50°C to 175°C
• Mounting Type: Surface Mount
• Package / Case: DO-213AC, MINI-MELF, SOD-80 / SOD-80C

Substitutes are grouped into two categories based on voltage tolerance specification:

Category 1 - Standard Tolerance (±5%): Parts maintaining the original ±5% tolerance specification.

Category 2 - Tighter Tolerance (±2%): Parts offering improved voltage tolerance at ±2%, suitable for applications requiring higher precision voltage regulation.

All substitute parts are manufactured by Diotec Semiconductor and maintain Active product status with confirmed inventory availability.

Engineering Selection Recommendations

ZMM11 Selection Criteria:

The ZMM11 is a direct parametric equivalent to the ZMC11, maintaining identical electrical specifications including 11 V nominal zener voltage, 500 mW power rating, ±5% tolerance, and 20 Ohms maximum impedance. Both components share the same SOD-80C package configuration and operating temperature range. The primary distinction is packaging format: ZMM11 is supplied in Tape & Reel format with significantly higher inventory availability (42,600 units). Selection of ZMM11 is appropriate when tape and reel packaging accommodates assembly line requirements and inventory replenishment is prioritized.

ZMM11B Selection Criteria:

The ZMM11B provides identical electrical performance to the ZMC11 across all parameters except voltage tolerance, which is specified at ±2% compared to the original ±5%. This tighter tolerance specification qualifies ZMM11B for applications requiring enhanced voltage regulation precision. ZMM11B maintains the same SOD-80C package, operating temperature range, and power dissipation rating. Selection of ZMM11B is appropriate when circuit design specifications mandate voltage tolerance tighter than ±5%, and the component is supplied in Tape & Reel packaging with 30,892 units in stock.

All three parts maintain Active product status and are manufactured by Diotec Semiconductor, ensuring consistent quality and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can ZMM11 be used as a direct replacement for ZMC11?

A: Yes. The ZMM11 is a parametric equivalent with identical electrical specifications: 11 V nominal zener voltage, 500 mW power rating, ±5% tolerance, 20 Ohms maximum impedance, and identical operating temperature range. Both use the SOD-80C package. The difference is packaging format: ZMM11 is supplied in Tape & Reel while ZMC11 is supplied in bulk.

Q: What is the difference between ZMM11 and ZMM11B?

A: Both parts share identical electrical specifications except for voltage tolerance. ZMM11 specifies ±5% tolerance, while ZMM11B specifies ±2% tolerance. Both maintain 11 V nominal zener voltage, 500 mW power rating, and SOD-80C packaging. ZMM11B is selected when tighter voltage tolerance is required by circuit design specifications.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. ZMC11, ZMM11, and ZMM11B all use the DO-213AC, MINI-MELF, SOD-80 package configuration with SOD-80C supplier device package designation. PCB footprints designed for any of these parts are compatible with all three.

Q: What is the operating temperature range for these zener diodes?

A: All three parts operate across -50°C to 175°C junction temperature range (TJ), providing consistent thermal performance across the product line.

Q: Why would I select ZMM11B over ZMM11 if they have the same power rating and voltage?

A: ZMM11B is selected when application circuit design requires voltage tolerance tighter than ±5%. The ±2% tolerance specification of ZMM11B provides enhanced voltage regulation precision for sensitive analog circuits or precision reference applications.

Q: Is packaging format the only difference between ZMC11 and ZMM11?

A: Packaging format is the primary operational difference. ZMC11 is supplied in bulk packaging while ZMM11 is supplied in Tape & Reel format. All electrical parameters, thermal characteristics, and physical package dimensions are identical. Selection depends on assembly process requirements and inventory management strategy.

Q: What is the reverse leakage current specification for these parts?

A: All three parts specify 100 nanoamperes reverse leakage current measured at 8 V reverse bias (Vr), ensuring consistent leakage performance across the product line.
