Engineering Selection Recommendations

FR306G (Taiwan Semiconductor Corporation)

The FR306G is an active product offering identical electrical specifications to the FR306GP-TP across all critical parameters: 800V reverse voltage, 3A current rating, 1.3V forward voltage, and 500ns recovery time. This part is suitable for direct substitution in applications currently using the FR306GP-TP. The FR306G is available in Cut Tape packaging, which differs from the main part's Tape & Reel format. Both parts maintain ROHS3 compliance and identical temperature operating ranges.

PG308R_R2_00001 (Panjit International Inc.)

The PG308R_R2_00001 meets all critical electrical specifications and is classified as an active product. This part demonstrates superior reverse leakage characteristics (1 µA versus 5 µA at 800V), indicating lower standby current performance. The PG308R_R2_00001 is available in Tape & Reel packaging, matching the main part's format. ROHS3 compliance and temperature range specifications are identical. This part is suitable for direct substitution where lower leakage current provides system-level benefits.

Both substitute parts are active products, eliminating the obsolescence concern associated with the FR306GP-TP's Not For New Designs status.

Frequently Asked Questions (FAQ)

Q: Can FR306G be used as a direct replacement for FR306GP-TP?

A: Yes. The FR306G meets all critical electrical parameters: 800V reverse voltage, 3A current rating, 1.3V forward voltage at 3A, and 500ns recovery time. Both parts use the DO-201AD axial through-hole package and operate across -55°C to 150°C. The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status (Active versus Not For New Designs).

Q: What is the difference between FR306G and PG308R_R2_00001?

A: Both parts are electrically equivalent across all critical parameters. The PG308R_R2_00001 exhibits lower reverse leakage current (1 µA versus 5 µA at 800V), which may reduce standby power consumption in certain applications. The FR306G is available in Cut Tape packaging, while PG308R_R2_00001 is supplied in Tape & Reel format. Both are ROHS3 compliant and active products.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape) affects handling, storage, and assembly processes but does not alter electrical characteristics. Both packaging types contain identical diode components in DO-201AD configuration.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The FR306GP-TP, FR306G, and PG308R_R2_00001 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the FR306GP-TP being classified as Not For New Designs?

A: This classification indicates the manufacturer has discontinued active promotion and development of this part number. Existing inventory remains available, but new designs should utilize active alternatives such as FR306G or PG308R_R2_00001 to ensure long-term supply chain stability.

Q: Can these parts be used interchangeably in existing circuits?

A: Yes, provided the circuit design accommodates the DO-201AD through-hole package and the specified electrical parameters. All three parts share identical voltage ratings, current ratings, forward voltage characteristics, and recovery times, making them functionally interchangeable at the component level.
