Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HER208G-AP are identified based on strict equivalence of the following critical parameters:

• Voltage Rating: DC reverse voltage must equal 1000 V
• Current Rating: Average rectified current must equal 2 A
• Forward Voltage Drop: Maximum forward voltage at rated current must equal 1.7 V @ 2 A
• Recovery Characteristics: Fast recovery classification with reverse recovery time of 75 ns
• Reverse Leakage: Maximum reverse leakage current of 5 µA @ 1000 V
• Mounting Configuration: Through-hole axial package (DO-15 or DO-204AC equivalent)
• Temperature Range: Operating junction temperature range of -55°C to 150°C
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status

Substitution is valid when all electrical parameters match the specified tolerances and the physical package remains compatible with through-hole PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The HER208G A0G manufactured by Taiwan Semiconductor Corporation is a direct parametric equivalent to the HER208G-AP. Both components maintain identical electrical specifications across voltage rating, current capacity, forward voltage drop, and recovery characteristics. Both parts are Active product status and carry ROHS3 compliance with REACH unaffected designation, satisfying regulatory requirements for industrial and commercial applications.

The primary distinction between these parts is packaging format: the HER208G-AP is supplied in Tape & Box configuration, while the HER208G A0G is supplied in Cut Tape format. Both utilize the same DO-15 (DO-204AC) axial through-hole package, ensuring mechanical and electrical compatibility in PCB assembly. The capacitance specification shows a minor variance (30 pF versus 20 pF at 4V, 1MHz), which remains within acceptable tolerance for general-purpose rectification applications and does not affect substitution validity.

Selection between these parts should be based on packaging requirements, inventory availability, and supply chain considerations rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the HER208G A0G replace the HER208G-AP in existing circuit designs?

A: Yes. The HER208G A0G is a parametric equivalent with identical voltage rating (1000 V), current rating (2 A), forward voltage drop (1.7 V @ 2 A), and recovery characteristics (75 ns). Both components use the same DO-15 through-hole package, ensuring direct mechanical and electrical compatibility.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box packaging supplies components on continuous tape wound in a box, typically used for higher-volume automated assembly. Cut Tape supplies components on tape segments cut to specific lengths, typically used for smaller quantities or manual assembly. Both formats contain the same component in the same package; the difference is in handling and dispensing method.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both the HER208G-AP and HER208G A0G operate across the identical temperature range of -55°C to 150°C junction temperature and carry the same moisture sensitivity level (MSL 1 - Unlimited). Both are RoHS3 compliant and REACH unaffected.

Q: Does the capacitance difference (30 pF vs 20 pF) affect circuit performance?

A: The capacitance variance is minor and occurs at the same measurement conditions (4V, 1MHz). For general-purpose rectification applications, this difference does not impact circuit functionality or substitution validity. Applications requiring precise capacitance specifications should reference detailed circuit analysis.

Q: What is the base product number for these parts?

A: Both the HER208G-AP and HER208G A0G share the base product number HER208, indicating they are variants of the same core rectifier design from different manufacturers.

Q: Are both parts suitable for high-frequency switching applications?

A: Both parts are classified as Fast Recovery diodes with a reverse recovery time of 75 ns, meeting the speed requirements for switching applications up to the specified frequency limits. The fast recovery characteristic indicates suitability for applications requiring rapid diode turn-off.
