Equivalent & Substitute Parts for 30EPF06

Part Overview

The 30EPF06 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V DC reverse voltage and 30 A average rectified current in a Through Hole TO-247AC Modified package. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity. The diode features fast recovery characteristics with a reverse recovery time of 160 ns and operates across a junction temperature range of -40°C to 150°C. Due to its obsolete status and non-RoHS3 compliance, alternative components with active product status are available to meet current regulatory and supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30EPF06 is determined by matching the following critical electrical and mechanical parameters:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 30 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: TO-247 family variants (TO-247-2, TO-247-3, TO-247AD, ISOPLUS247™)

Compliance Parameters:

• RoHS Status: Active product status preferred
• REACH Status: REACH Unaffected (all candidates meet this requirement)

All substitute parts listed maintain the core electrical specifications of 600 V reverse voltage and 30 A average rectified current. Variations in forward voltage drop, reverse recovery time, reverse leakage current, and operating temperature range are secondary parameters that may differ between candidates. Package variants within the TO-247 family are mechanically compatible with standard through-hole PCB layouts, though specific pin configurations should be verified for individual applications.

Parameter Comparison

Engineering Selection Recommendations

VS-30APF06-M3 (Vishay General Semiconductor - Diodes Division)

This part is a parametric equivalent manufactured by the same supplier as the 30EPF06. It maintains identical electrical specifications including 600 V reverse voltage, 30 A average rectified current, 1.41 V forward voltage drop, and 160 ns reverse recovery time. The primary distinction is active product status and ROHS3 compliance. The package variant is TO-247-3 rather than TO-247-2 Modified, requiring verification of PCB layout compatibility. This option provides the closest electrical match with current regulatory compliance.

APT30D60BG (Microchip Technology)

This part meets the core voltage and current requirements of 600 V and 30 A. It features improved reverse recovery time of 85 ns compared to the 30EPF06, resulting in lower switching losses. Forward voltage drop is 1.8 V, representing a 0.39 V increase. Reverse leakage current is 250 µA, higher than the 30EPF06 specification. Operating temperature range extends to -55°C to 175°C, providing broader thermal coverage. The part is ROHS3 compliant and maintains active product status. Package is TO-247-2, matching the original part footprint.

DSEP30-06A (IXYS)

This part is rated for 600 V and 30 A with forward voltage of 1.6 V and reverse recovery time of 35 ns, representing significant performance improvement over the 30EPF06. It belongs to the HiPerFRED™ series, indicating optimized fast recovery characteristics. Reverse leakage current is 250 µA. Operating temperature range is -55°C to 175°C. The package is TO-247-2, compatible with the original footprint. ROHS3 compliance and active product status are confirmed.

DSEP30-06B (IXYS)

This part meets the 600 V and 30 A specifications with the fastest reverse recovery time of 30 ns among all candidates. Forward voltage drop is 2.51 V, the highest of all options, resulting in increased power dissipation. It is packaged in ISOPLUS247™, a variant of the TO-247 family that requires PCB layout verification for compatibility. The part is ROHS3 compliant with active product status. Operating temperature range is -55°C to 175°C. This option is suitable for applications where switching speed is prioritized and thermal management accommodates the higher forward voltage drop.

Frequently Asked Questions (FAQ)

Q: Can the 30EPF06 be directly replaced with any of these substitute parts?

A: All substitute parts share the core electrical specifications of 600 V reverse voltage and 30 A average rectified current, making them functionally equivalent for applications requiring these ratings. However, package variants must be verified for PCB compatibility. The TO-247-3 variant (VS-30APF06-M3) and ISOPLUS247™ variant (DSEP30-06B) may require layout adjustments compared to the original TO-247-2 package.

Q: What is the significance of the differences in forward voltage drop?

A: Forward voltage drop directly affects power dissipation in the diode. The 30EPF06 and VS-30APF06-M3 both specify 1.41 V at 30 A. The APT30D60BG specifies 1.8 V, DSEP30-06A specifies 1.6 V, and DSEP30-06B specifies 2.51 V. Higher forward voltage results in greater heat generation. Applications with tight thermal budgets should account for these differences when selecting a substitute.

Q: Why do reverse recovery times vary significantly among the candidates?

A: Reverse recovery time is a function of diode technology and design. The 30EPF06 has 160 ns recovery time, while IXYS HiPerFRED™ parts (DSEP30-06A and DSEP30-06B) achieve 35 ns and 30 ns respectively. Faster recovery reduces switching losses and electromagnetic interference, beneficial in high-frequency applications. Selection depends on circuit switching frequency requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant. The original 30EPF06 is non-compliant. If regulatory compliance is required for new designs or procurement, any of the substitute parts satisfy this requirement.

Q: What is the difference between TO-247-2, TO-247-3, TO-247AD, and ISOPLUS247™ packages?

A: These are all variants of the TO-247 through-hole package family with different pin configurations and thermal characteristics. TO-247-2 and TO-247-3 differ in pin arrangement. TO-247AD is a variant used by IXYS. ISOPLUS247™ is a proprietary IXYS variant with enhanced thermal performance. PCB layout and mounting hardware must be verified for each specific package variant before substitution.

Q: Which substitute part is recommended for new designs?

A: Selection depends on application requirements. For closest electrical match with current compliance, VS-30APF06-M3 is recommended. For improved switching performance with standard TO-247-2 footprint, APT30D60BG or DSEP30-06A are suitable. For maximum switching speed, DSEP30-06B is appropriate if thermal management accommodates the higher forward voltage drop.

Q: What is the operating temperature range difference, and does it matter?

A: The 30EPF06 operates from -40°C to 150°C. All substitute parts extend this to -55°C to 175°C, providing broader thermal coverage. This is advantageous for applications in extreme temperature environments but does not restrict substitution in applications within the original temperature range.

Q: Is inventory availability a consideration for substitution?

A: Inventory levels vary among candidates. VS-30APF06-M3 has 1,038 units available. APT30D60BG has 109,480 units. DSEP30-06A has 33,491 units. DSEP30-06B has 2,318 units. Availability should be verified with suppliers for production requirements.
