Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HFA08PB60 are classified based on strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 600 V
• Current - Average Rectified (Io): Must equal or exceed 8 A
• Speed Classification: Must be Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Must be Through Hole
• Package / Case: Must be TO-247-2 or compatible TO-247 variant

Parametric Equivalents maintain identical or superior electrical ratings within the same package family, ensuring direct functional replacement without circuit redesign.

Manufacturer Recommended Substitutes may exceed the original specifications in current rating or other parameters while maintaining voltage class and package compatibility, suitable for applications requiring higher performance margins.

Parameter Comparison

Engineering Selection Recommendations

VS-HFA08PB60-N3 (Parametric Equivalent): This part is the direct parametric equivalent of HFA08PB60, manufactured by the same supplier (Vishay General Semiconductor - Diodes Division). It maintains identical electrical specifications: 600 V reverse voltage, 8 A average rectified current, 1.7 V forward voltage at 8 A, 55 ns reverse recovery time, and 5 µA reverse leakage current. The VS-HFA08PB60-N3 is classified as Active product status, ensuring ongoing availability and supply chain support. This part is ROHS3 Compliant, addressing regulatory requirements where the original HFA08PB60 (RoHS non-compliant) may present compliance constraints. The identical electrical and thermal specifications (-55 to 150 °C junction temperature range) enable direct substitution without circuit modification. Current inventory of 1373 pieces supports production requirements.

APT30D60BG (Manufacturer Recommended Substitute): This Microchip Technology part is rated for 600 V reverse voltage with a higher current capacity of 30 A average rectified current, compared to the 8 A rating of HFA08PB60. The APT30D60BG maintains Fast Recovery speed classification and TO-247-2 package compatibility. The reverse recovery time is 85 ns (versus 55 ns for HFA08PB60) and reverse leakage current is 250 µA @ 600 V (versus 5 µA for HFA08PB60). The operating temperature range extends to 175 °C junction temperature. This part is Active status and ROHS3 Compliant. The APT30D60BG is suitable for applications where higher current capacity provides design margin or where future performance upgrades are anticipated. Extensive inventory of 109480 pieces ensures supply availability. Selection of this part requires verification that the circuit design accommodates the higher current rating and the specified electrical parameter differences.

Frequently Asked Questions (FAQ)

Q: Can VS-HFA08PB60-N3 be used as a direct replacement for HFA08PB60?

A: Yes. The VS-HFA08PB60-N3 is a parametric equivalent with identical electrical specifications: 600 V reverse voltage, 8 A average rectified current, 1.7 V forward voltage at 8 A, 55 ns reverse recovery time, and 5 µA reverse leakage current. Both parts use the TO-247-2 package and Through Hole mounting. The primary difference is product status (Active versus Obsolete) and RoHS compliance (ROHS3 Compliant versus non-compliant). Direct substitution is supported without circuit redesign.

Q: What are the key differences between HFA08PB60 and APT30D60BG?

A: The APT30D60BG has a higher current rating (30 A versus 8 A), longer reverse recovery time (85 ns versus 55 ns), and higher reverse leakage current (250 µA @ 600 V versus 5 µA @ 600 V). Both maintain 600 V reverse voltage rating and Fast Recovery speed classification. The APT30D60BG extends the operating temperature range to 175 °C. These differences indicate the APT30D60BG is a higher-performance variant suitable for applications requiring greater current capacity or thermal margin.

Q: Are both substitute parts compatible with the TO-247-2 package footprint?

A: Yes. Both VS-HFA08PB60-N3 and APT30D60BG use TO-247-2 package classification with Through Hole mounting type, ensuring mechanical and footprint compatibility with the original HFA08PB60 design.

Q: What is the significance of the RoHS compliance difference?

A: The HFA08PB60 is RoHS non-compliant, while VS-HFA08PB60-N3 and APT30D60BG are ROHS3 Compliant. In applications subject to RoHS regulations or customer requirements, the compliant alternatives (VS-HFA08PB60-N3 or APT30D60BG) must be selected. The VS-HFA08PB60-N3 provides compliance while maintaining identical electrical specifications.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring 8 A at 600 V with Fast Recovery characteristics, the VS-HFA08PB60-N3 is the recommended choice due to parametric equivalence, Active product status, and ROHS3 compliance. The APT30D60BG is suitable if the application benefits from higher current capacity (30 A) or extended temperature range (to 175 °C).

Q: What inventory considerations apply to these parts?

A: HFA08PB60 has 1318 pieces in stock (Obsolete status). VS-HFA08PB60-N3 has 1373 pieces available (Active status). APT30D60BG has 109480 pieces in stock (Active status). For long-term supply security, Active status parts (VS-HFA08PB60-N3 or APT30D60BG) are preferred over the Obsolete HFA08PB60.
