ER1C-TP General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The ER1C-TP is a general purpose rectifier diode manufactured by Micro Commercial Co, rated for 150V DC reverse voltage and 1A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The ER1C-TP operates across a junction temperature range of -50°C to 150°C and features fast recovery characteristics with a reverse recovery time of 50 nanoseconds, making it suitable for standard rectification applications requiring moderate switching speeds.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ER1C-TP is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Voltage - DC Reverse (Vr) Maximum: 150 V
• Current - Average Rectified (Io): 1 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 150 V
• Capacitance @ Vr, F: 45 pF @ 4V, 1MHz
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters:

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -50°C to 150°C

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all electrical, mechanical, and compliance criteria are classified as direct substitutes. The ER1C-TP base product number ER1C serves as the common reference for the substitute part family.

Parameter Comparison
