MURA220T3 Equivalent & Substitute Parts

Part Overview

The MURA220T3 is an ultra-fast rectifier diode manufactured by onsemi, rated for 200 V DC reverse voltage and 2 A average rectified current in a surface mount SMA package (DO-214AC). This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement.

The MURA220T3 serves as a general-purpose fast recovery rectifier suitable for applications requiring efficient switching performance at moderate voltage and current levels. Due to its obsolete status, equivalent active alternatives are required to maintain design continuity and ensure component availability.

Substitute Part Grouping Explanation

Substitution of the MURA220T3 is determined by the following critical electrical and mechanical parameters:

Primary Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V minimum
Current - Average Rectified (Io): 2 A minimum
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Mounting Type: Surface Mount
Package / Case: DO-214AC, SMA or compatible surface mount package

Secondary Compatibility Factors:

Reverse Recovery Time (trr): ≤ 35 ns preferred for direct replacement
Voltage - Forward (Vf) (Max) @ If: ≤ 950 mV @ 2 A preferred
Current - Reverse Leakage @ Vr: ≤ 2 µA @ 200 V preferred
RoHS Compliance: ROHS3 Compliant preferred for new designs
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into three categories based on electrical performance alignment:

Category 1 - Direct Electrical Equivalent (Preferred): Parts matching all primary criteria with minimal deviation in secondary parameters.

Category 2 - Functional Equivalent with Minor Deviations: Parts meeting primary voltage and current requirements with acceptable variations in recovery time or forward voltage.

Category 3 - Package Variant Equivalent: Parts meeting electrical requirements but in alternative surface mount packages (SMB vs. SMA).

Engineering Selection Recommendations

MURA220T3G (onsemi) - Primary Recommendation

MURA220T3G is the direct equivalent replacement for MURA220T3. This part maintains identical electrical specifications across all critical parameters: 200 V reverse voltage, 2 A average rectified current, 950 mV forward voltage at 2 A, and 35 ns reverse recovery time. The part is manufactured by the same supplier (onsemi) and uses the identical package (DO-214AC, SMA). MURA220T3G holds active product status and is ROHS3 compliant, making it suitable for new designs and long-term procurement. Inventory availability is substantial at 245,400 pieces.

BYG22D-E3/TR (Vishay General Semiconductor - Diodes Division) - Secondary Recommendation

BYG22D-E3/TR qualifies as a functional equivalent with superior electrical performance characteristics. It meets the 200 V reverse voltage and 2 A current requirements in the same DO-214AC, SMA package. The part exhibits improved reverse recovery time (25 ns versus 35 ns) and lower reverse leakage current (1 µA versus 2 µA). Forward voltage is slightly elevated at 1.1 V compared to 950 mV, representing a 150 mV increase. BYG22D-E3/TR is active, ROHS3 compliant, and available in quantity (137,590 pieces). This part is suitable for applications where improved switching performance is beneficial.

UF2D_R1_00001 (Panjit International Inc.) - Package Variant Alternative

UF2D_R1_00001 provides electrical equivalence with a package variant consideration. It matches the 200 V reverse voltage and 2 A current rating with comparable forward voltage (1000 mV at 2 A) and reverse recovery time (50 ns). The critical difference is the package format: UF2D_R1_00001 uses DO-214AA (SMB) instead of DO-214AC (SMA). SMB packages are physically larger than SMA packages. This substitution requires PCB layout verification to confirm mechanical compatibility. The part is active and ROHS3 compliant with adequate inventory (1,962 pieces).

CMR1F-02M TR13 PBFREE and HS2DA - Limited Suitability

CMR1F-02M TR13 PBFREE and HS2DA do not meet the full current requirement of 2 A. CMR1F-02M TR13 PBFREE is rated for 1 A maximum, and HS2DA is rated for 1.5 A maximum. These parts are suitable only for applications where the actual circuit current requirement is below their respective ratings. Both parts are active and ROHS3 compliant but represent functional downgrades from the original specification.

Frequently Asked Questions (FAQ)

Q: Can MURA220T3G be used as a direct replacement for MURA220T3?

A: Yes. MURA220T3G is the direct equivalent. Both parts share identical electrical specifications (200 V, 2 A, 950 mV forward voltage, 35 ns recovery time) and the same package (DO-214AC, SMA). MURA220T3G is active and ROHS3 compliant, whereas MURA220T3 is obsolete and non-compliant. No circuit modifications are required.

Q: What is the difference between DO-214AC (SMA) and DO-214AA (SMB) packages?

A: DO-214AC (SMA) and DO-214AA (SMB) are both surface mount diode packages but differ in physical dimensions. SMB packages are larger than SMA packages. If substituting UF2D_R1_00001 (SMB) for MURA220T3 (SMA), PCB layout must be verified to confirm the larger package fits within the available space. Electrical performance is equivalent.

Q: Why does BYG22D-E3/TR have a higher forward voltage (1.1 V) than MURA220T3 (950 mV)?

A: BYG22D-E3/TR uses avalanche technology, whereas MURA220T3 uses standard technology. The forward voltage difference reflects the different semiconductor technologies employed. The 150 mV increase results in slightly higher power dissipation but is offset by superior reverse recovery time (25 ns versus 35 ns) and lower reverse leakage current (1 µA versus 2 µA). Circuit thermal analysis should confirm acceptability in the target application.

Q: Can CMR1F-02M TR13 PBFREE or HS2DA replace MURA220T3 in all applications?

A: No. CMR1F-02M TR13 PBFREE is rated for 1 A maximum, and HS2DA is rated for 1.5 A maximum. MURA220T3 is rated for 2 A. These parts can only substitute if the actual circuit current requirement is below their respective ratings. Operating these parts at or above their current ratings will cause failure. Circuit current analysis is mandatory before substitution.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. MURA220T3 is non-compliant (obsolete), whereas all substitute parts listed are ROHS3 compliant. For new designs and procurement, ROHS3 compliant parts are required in most jurisdictions and by most OEMs.

Q: Is reverse recovery time critical for my application?

A: Reverse recovery time (trr) determines switching speed and affects power dissipation in switching applications. MURA220T3 has 35 ns recovery time. BYG22D-E3/TR offers superior performance at 25 ns, while CMR1F-02M TR13 PBFREE and HS2DA have longer recovery times (150 ns and 50 ns respectively). For high-frequency switching applications, shorter recovery times reduce switching losses. For low-frequency or linear applications, recovery time is less critical.

Q: What is the significance of reverse leakage current specifications?

A: Reverse leakage current (Ir) represents the small current flowing through the diode when reverse biased. MURA220T3 specifies 2 µA at 200 V. Lower leakage current (BYG22D-E3/TR at 1 µA, UF2D_R1_00001 at 1 µA) indicates better blocking performance and lower standby power consumption. Higher leakage current (CMR1F-02M TR13 PBFREE and HS2DA at 5 µA) is acceptable for most applications but may impact low-power standby circuits.

Q: Are all substitute parts available in the same quantities as MURA220T3?

A: No. MURA220T3 has 1,900 pieces in stock. MURA220T3G has significantly higher availability at 245,400 pieces. Other substitutes vary: BYG22D-E3/TR (137,590 pieces), HS2DA (15,265 pieces), UF2D_R1_00001 (1,962 pieces), and CMR1F-02M TR13 PBFREE (779 pieces). For high-volume production, MURA220T3G or BYG22D-E3/TR are preferred due to superior inventory levels.
