BAV170-TP Equivalent & Substitute Parts

Part Overview

The BAV170-TP is a general-purpose diode array manufactured by Micro Commercial Co, configured as a 1 Pair Common Cathode design in a surface mount SOT-23-3 package. This component is rated for 85 V DC reverse voltage with 215 mA average rectified current per diode and operates at a maximum junction temperature of 150°C. The part is currently in active production status and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical packaging allow direct replacement in circuit applications without design modification.

Substitute Part Grouping Explanation

Substitution of the BAV170-TP is permissible when an alternative part meets or exceeds all critical electrical parameters while maintaining identical mechanical packaging. The substitution logic is based on the following key parameters:

Electrical Equivalence Criteria:

• Diode Configuration: 1 Pair Common Cathode (must match exactly)
• Voltage - DC Reverse (Vr) (Max): 85 V (substitute must equal or exceed)
• Current - Average Rectified (Io) (per Diode): 215 mA (DC) (substitute must equal or exceed)
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA (substitute must equal or be lower)
• Reverse Recovery Time (trr): 3 µs (substitute must equal or be faster)
• Current - Reverse Leakage @ Vr: 5 nA @ 75 V (substitute must equal or be lower)
• Operating Temperature - Junction (Max): 150°C (substitute must equal or exceed)

Mechanical Equivalence Criteria:

• Package / Case: TO-236-3, SC-59, SOT-23-3 (must match exactly)
• Mounting Type: Surface Mount (must match exactly)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (substitute must maintain compliance)

The BAV170Q-13-F from Diodes Incorporated satisfies all electrical and mechanical equivalence criteria and is therefore classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

BAV170Q-13-F (Diodes Incorporated) is a direct parametric equivalent to the BAV170-TP. Both parts are active production components with ROHS3 compliance. The BAV170Q-13-F carries AEC-Q101 automotive qualification and an extended operating temperature range of −65°C to 150°C, compared to the BAV170-TP specification of 150°C maximum. All critical electrical parameters—reverse voltage, rectified current, forward voltage, recovery time, and leakage current—are identical. Mechanical packaging is identical, with both parts supplied in SOT-23-3 surface mount configuration. Selection between these parts depends on application requirements: the BAV170Q-13-F is suitable for automotive and extended temperature applications, while the BAV170-TP serves general-purpose applications within the specified 150°C maximum junction temperature.
