CMR1-01M TR13 Equivalent & Substitute Parts

Part Overview

The CMR1-01M TR13 is a general-purpose rectifier diode manufactured by Central Semiconductor Corp, rated for 100 V DC reverse voltage and 1 A average rectified current in a surface mount SMA package (DO-214AC). This component operates across a junction temperature range of -65°C to 150°C and features standard recovery characteristics with reverse recovery time exceeding 500 ns.

The CMR1-01M TR13 is classified as an active product. Equivalent and substitute parts are identified based on matching electrical specifications (voltage rating, current rating, forward voltage, and recovery characteristics) and mechanical compatibility (surface mount SMA packaging). Substitute parts enable design flexibility, support supply chain continuity, and provide options across multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the CMR1-01M TR13 is determined by the following critical parameters:

Electrical Compatibility Requirements:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 100 V
Current - Average Rectified (Io): Must equal or exceed 1 A
Package / Case: Must be DO-214AC (SMA) surface mount
Operating Temperature - Junction: Must accommodate the application's thermal requirements

Recovery Characteristics: Substitute parts are grouped into two categories based on recovery speed:

Standard Recovery (>500 ns): Direct functional equivalents with identical switching behavior
Fast Recovery (≤500 ns): Enhanced performance alternatives with improved switching characteristics

Forward Voltage Considerations: The CMR1-01M TR13 specifies a maximum forward voltage of 1.1 V @ 1 A. Substitute parts with lower forward voltage (0.9 V to 1.0 V) offer improved efficiency with no functional incompatibility. Substitute parts with forward voltage up to 1.1 V maintain electrical equivalence.

Compliance and Certification: Substitute parts are available with standard industrial compliance (ROHS3, REACH Unaffected) and automotive-grade options (AEC-Q101 qualified). Selection depends on application requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CMR1-01M TR13 with a fast recovery diode?

A: Yes. Fast recovery diodes (≤500 ns) are functionally compatible with the CMR1-01M TR13 (standard recovery >500 ns). Fast recovery variants offer improved switching performance and reduced switching losses. All listed fast recovery substitutes maintain the required 100 V voltage rating and 1 A current rating. Electrical compatibility is maintained across all fast recovery alternatives.

Q: What is the difference between standard recovery and fast recovery diodes?

A: Recovery speed refers to the reverse recovery time (trr), which is the time required for the diode to transition from forward conduction to reverse blocking. The CMR1-01M TR13 specifies standard recovery (>500 ns). Fast recovery substitutes (≤500 ns) switch more rapidly, reducing switching losses and electromagnetic interference. Both types are electrically compatible when voltage and current ratings match.

Q: Are all substitute parts available in the same SMA package?

A: Yes. All listed substitute parts use the DO-214AC (SMA) surface mount package, ensuring mechanical and footprint compatibility with the CMR1-01M TR13. No PCB layout modifications are required.

Q: What does "Not For New Designs" product status mean?

A: Parts marked "Not For New Designs" (ES1B-LTP and GS1B-LTP) are legacy products that remain available for existing system support and replacement applications. These parts are not recommended for incorporation into new product designs. For new designs, select from active product alternatives.

Q: Which substitute part offers the lowest forward voltage drop?

A: ESH1B-E3/61T offers the lowest forward voltage at 900 mV @ 1 A, compared to the CMR1-01M TR13 at 1.1 V @ 1 A. This represents a 200 mV reduction, resulting in improved power efficiency. ES1B variants (ES1B-13-F, ES1B-E3/5AT, ES1B-E3/61T, ES1BHE3_A/H, ES1BHE3_A/I) offer 920 mV @ 1 A, providing a 180 mV reduction.

Q: Are automotive-qualified alternatives available?

A: Yes. ES1BHE3_A/H and ES1BHE3_A/I are AEC-Q101 qualified automotive-grade diodes. Both maintain the 100 V voltage rating, 1 A current rating, and SMA package. These parts are suitable for automotive applications requiring component-level qualification.

Q: What is the operating temperature range difference between substitute parts?

A: The CMR1-01M TR13 operates from -65°C to 150°C. Most fast recovery substitutes operate from -55°C to 150°C, providing a 10°C reduction in minimum temperature capability. EGF1B, ES1B-LTP, and ESH1B-E3/61T extend the maximum temperature to 175°C, providing 25°C additional high-temperature capability. Application thermal requirements determine the appropriate selection.

Q: Can I use a substitute part with higher reverse leakage current?

A: Reverse leakage current specifications range from 1 µA to 10 µA @ 100 V across the substitute parts. The CMR1-01M TR13 specifies 5 µA @ 100 V. Parts with higher leakage (EGF1B and GS1B-LTP at 10 µA) are functionally compatible but exhibit slightly higher standby current. Parts with lower leakage (ESH1B-E3/61T at 1 µA) offer improved standby performance. Selection depends on application power consumption requirements.

Q: What is the significance of capacitance specifications?

A: Capacitance values range from 8 pF to 20 pF @ 4V, 1MHz. The CMR1-01M TR13 specifies 8 pF. Higher capacitance values (US1B-13-F at 20 pF) may affect high-frequency circuit performance. Lower capacitance values (ES1B variants at 10 pF) provide improved high-frequency characteristics. For applications operating above 1 MHz, select substitutes with capacitance values closest to the original specification.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant except EGF1B and the CMR1-01M TR13, for which RoHS status is not specified. ROHS3 compliance is a standard requirement for new product designs and ensures compliance with hazardous substance restrictions.
