Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 1 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package / Case: T-18, Axial
• Supplier Device Package: TS-1

Compliance & Status:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The HT13G A0G meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The HT13G A0G is a direct functional and mechanical equivalent to the HT13G A1G. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, package configuration, and compliance certifications. The primary distinction is product status: the HT13G A1G is discontinued at DiGi Electronics, while the HT13G A0G maintains active product status with current inventory availability (972 pieces in stock).

For applications requiring the HT13G A1G, the HT13G A0G provides complete substitution without circuit redesign or performance degradation. Both parts satisfy ROHS3 compliance requirements and REACH unaffected status, ensuring regulatory alignment. The identical operating temperature range (-55°C to 150°C) and fast recovery characteristics (50 ns reverse recovery time) support direct replacement in existing designs.
