Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HER207-TP are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Operating Temperature - Junction: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant

All substitute parts listed meet or exceed these electrical specifications and are compatible with the through-hole mounting footprint. Variations in secondary parameters such as reverse recovery time, reverse leakage current, and capacitance remain within acceptable ranges for general-purpose rectification applications.

Engineering Selection Recommendations

HER207G (Taiwan Semiconductor Corporation)

The HER207G is an active product that provides direct electrical equivalence to the HER207-TP. It maintains identical voltage, current, and forward voltage specifications with matching reverse recovery time of 75 ns. The HER207G is ROHS3 compliant and REACH unaffected, ensuring regulatory compliance for new designs. This part is available in higher inventory quantities (4585 pcs) and is supplied in Cut Tape packaging, suitable for automated assembly processes.

UF208G_R2_00001 (Panjit International Inc.)

The UF208G_R2_00001 is an active product that meets all critical electrical parameters of the HER207-TP. It exhibits superior reverse leakage current performance (1 µA versus 5 µA at 800 V), which may provide operational advantages in low-leakage applications. The reverse recovery time is 100 ns, which remains within fast recovery classification. This part is ROHS3 compliant and REACH unaffected. It is supplied in Tape & Reel packaging and maintains adequate inventory availability (965 pcs).

Both substitute parts are suitable for direct replacement in applications requiring 800 V, 2 A general-purpose rectification with through-hole mounting. Selection between HER207G and UF208G_R2_00001 depends on packaging requirements, inventory lead times, and specific application sensitivity to reverse leakage current and recovery time characteristics.

Frequently Asked Questions (FAQ)

Q: Can HER207G be used as a direct replacement for HER207-TP?

A: Yes. The HER207G meets all critical electrical specifications: 800 V reverse voltage, 2 A average rectified current, 1.7 V forward voltage at 2 A, and 75 ns reverse recovery time. Both components use identical through-hole DO-15 packaging and operate across the same temperature range (-55°C to 150°C). The HER207G is an active product with established supply availability.

Q: What is the difference between HER207G and UF208G_R2_00001?
