HS3F V7G Equivalent & Substitute Parts

Part Overview

The HS3F V7G is a general-purpose rectifier diode rated for 300 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. The part operates across a junction temperature range of -55°C to 150°C and features fast recovery characteristics with a reverse recovery time of 50 ns, making it suitable for standard rectification applications requiring moderate voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS3F V7G is determined by electrical and mechanical parameter equivalence within the general-purpose rectifier diode category. The critical parameters governing substitution are:

• Voltage Rating: Maximum DC reverse voltage of 300 V
• Current Rating: Average rectified current of 3 A
• Package Type: DO-214AB (SMC) surface mount configuration
• Speed Classification: Fast recovery diode with reverse recovery time of 50 ns
• Reverse Leakage: 10 µA at 300 V
• Capacitance: 80 pF at 4 V, 1 MHz
• Temperature Range: -55°C to 150°C junction operating range
• Compliance: ROHS3 compliance and MSL 1 rating

Parts meeting all these parameters are classified as direct electrical and mechanical equivalents. The HS3F manufactured by SURGE meets all specified parameters and qualifies as a substitute part.

Parameter Comparison

Engineering Selection Recommendations

The HS3F manufactured by SURGE is a direct substitute for the discontinued HS3F V7G from Taiwan Semiconductor Corporation. Both parts are ROHS3 compliant and carry MSL 1 rating, indicating equivalent environmental and regulatory compliance. The SURGE variant is currently in active product status with 4,100 units available in inventory, compared to the discontinued Taiwan Semiconductor version. All electrical parameters, including voltage rating, current capacity, recovery time, and thermal operating range, are identical. The DO-214AB surface mount package ensures mechanical compatibility with existing PCB layouts and assembly processes. Selection of the SURGE HS3F is supported by complete parameter equivalence and active product availability.

Frequently Asked Questions (FAQ)

Q: Can the HS3F from SURGE be used as a direct replacement for the HS3F V7G?

A: Yes. Both parts share identical electrical specifications including 300 V reverse voltage rating, 3 A average rectified current, 50 ns reverse recovery time, and DO-214AB surface mount packaging. All critical parameters for rectifier diode functionality are equivalent.

Q: Are there any differences in compliance or environmental ratings between these parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The Taiwan Semiconductor version lists REACH as unaffected, while the SURGE version lists REACH status as vendor undefined. Both meet the specified compliance requirements for general-purpose rectifier applications.

Q: What is the significance of the DO-214AB package designation?

A: DO-214AB (also designated SMC) is a surface mount package for semiconductor diodes. Both the original and substitute parts use this identical package, ensuring compatibility with existing PCB footprints, solder reflow processes, and automated assembly equipment without design modification.

Q: How do the reverse recovery time specifications affect circuit performance?

A: Both parts specify 50 ns reverse recovery time, classifying them as fast recovery diodes. This parameter determines switching speed in rectification circuits and is critical for applications requiring rapid diode turn-off. Identical specifications ensure equivalent performance in switching and rectification applications.

Q: Is the forward voltage specification relevant for substitution?

A: The SURGE HS3F provides forward voltage data (1 V @ 3 A) while the Taiwan Semiconductor version does not include this specification in the provided data. However, this does not affect substitution validity, as the critical electrical parameters for rectifier operation are fully matched.

Q: What inventory considerations apply to this substitution?

A: The original HS3F V7G is discontinued with 1,123 units listed in stock. The SURGE HS3F is an active product with 4,100 units available, providing superior long-term procurement security and supply chain continuity for ongoing production requirements.
