Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SM4006PL-TP are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 800 V
• Current - Average Rectified (Io): Equal to or greater than 1 A
• Mounting Type: Surface Mount
• Package Category: SOD-123F or compatible surface mount package
• RoHS Status: ROHS3 Compliant
• MSL: Level 1 (Unlimited)

Secondary Compatibility Factors:

• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Current - Reverse Leakage @ Vr: Acceptable for application requirements
• Operating Temperature Range: Sufficient for intended thermal environment
• Product Status: Active

Substitute parts are grouped into two categories based on voltage rating: parts rated at 800 V (direct voltage match) and parts rated at 1000 V (higher voltage capability with backward compatibility).

Parameter Comparison

Engineering Selection Recommendations

Direct Voltage Match (800 V Rating):

The CRF02(TE85L,Q,M) from Toshiba Semiconductor and Storage maintains the 800 V voltage rating of the SM4006PL-TP. However, this part is rated for 500 mA average rectified current, which is 50% of the SM4006PL-TP rating. This part is suitable only for applications requiring 500 mA or less. The CRF02(TE85L,Q,M) features fast recovery characteristics (≤500ns) compared to the standard recovery (>500ns) of the SM4006PL-TP, with a reverse recovery time of 100 ns. All parts maintain ROHS3 compliance and MSL 1 rating. The operating temperature range of the CRF02(TE85L,Q,M) is -40 to 150°C, which is narrower than the SM4006PL-TP range of -65 to 175°C.

Higher Voltage Rating (1000 V Rating):

The RS1MWF-7 from Diodes Incorporated and CGRKM4007-HF from Comchip Technology both provide 1000 V voltage rating with 1 A current capability, offering higher voltage margin than the SM4006PL-TP. Both parts maintain ROHS3 compliance and MSL 1 rating. The RS1MWF-7 features fast recovery characteristics (≤500ns) with 500 ns reverse recovery time and lower capacitance (8pF @ 1V, 1MHz). The CGRKM4007-HF maintains standard recovery characteristics (>500ns) matching the SM4006PL-TP recovery speed profile. Both 1000 V rated parts operate within -55 to 150°C temperature range, which is narrower than the SM4006PL-TP at the lower end (-65°C minimum).

All substitute parts are Active product status with ROHS3 compliance and REACH Unaffected status, maintaining regulatory equivalence with the SM4006PL-TP.

Frequently Asked Questions (FAQ)

Q: Can the CRF02(TE85L,Q,M) replace the SM4006PL-TP in all applications?

A: The CRF02(TE85L,Q,M) is rated for 500 mA average rectified current, while the SM4006PL-TP is rated for 1 A. The CRF02(TE85L,Q,M) can only replace the SM4006PL-TP in applications requiring 500 mA or less. Both maintain 800 V voltage rating and SOD-123F package compatibility.

Q: What is the advantage of using RS1MWF-7 or CGRKM4007-HF over the SM4006PL-TP?

A: Both RS1MWF-7 and CGRKM4007-HF provide 1000 V voltage rating compared to the SM4006PL-TP 800 V rating. This higher voltage rating provides additional safety margin in high-voltage applications. Both maintain 1 A current capability and SOD-123F package compatibility. The trade-off is a narrower operating temperature range (-55 to 150°C versus -65 to 175°C).

Q: Are all substitute parts compatible with the SM4006PL-TP PCB footprint?

A: The SM4006PL-TP, RS1MWF-7, and CGRKM4007-HF all use SOD-123F package category. The CRF02(TE85L,Q,M) uses S-FLAT (1.6x3.5) package, which differs from SOD-123F. Verify PCB footprint compatibility before substitution.

Q: Do all substitute parts meet the same regulatory compliance as the SM4006PL-TP?

A: All substitute parts listed are ROHS3 compliant and have REACH Unaffected status, matching the SM4006PL-TP regulatory profile. All parts maintain MSL 1 (Unlimited) moisture sensitivity level.

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

A: The SM4006PL-TP features standard recovery (>500ns) while RS1MWF-7 and CRF02(TE85L,Q,M) feature fast recovery (≤500ns). Fast recovery diodes have shorter reverse recovery time, reducing switching losses in high-frequency applications. Standard recovery diodes are suitable for lower frequency rectification applications.

Q: Can I use a 1000 V rated diode in place of an 800 V rated diode?

A: Yes, a 1000 V rated diode (RS1MWF-7 or CGRKM4007-HF) can replace an 800 V rated diode (SM4006PL-TP) in applications where the circuit voltage does not exceed 800 V. The higher voltage rating provides additional safety margin without affecting circuit operation at lower voltages.

Q: What is the impact of forward voltage difference between substitute parts?

A: The SM4006PL-TP has 1.1 V forward voltage at 1 A, while RS1MWF-7 has 1.3 V at 1 A and CGRKM4007-HF has 1.1 V at 1 A. Higher forward voltage results in increased power dissipation. The CRF02(TE85L,Q,M) has 3 V forward voltage at 500 mA, which is significantly higher due to its lower current rating. Verify thermal design compatibility when substituting parts with different forward voltage characteristics.
