TSF20H150C-S Equivalent & Substitute Parts

Part Overview

The TSF20H150C-S is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 150 V DC reverse voltage and 10 A average rectified current in a through-hole TO-220-3 package with isolated tab. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory requirements necessitate alternative sourcing from qualified manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSF20H150C-S is determined by strict equivalence of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Technology: Schottky
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Operating Temperature - Junction: -55°C to 150°C
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Within component design specifications
• Current - Reverse Leakage @ Vr: Within component design specifications
• Current - Average Rectified (Io): Equal or greater capacity

The substitute part STF20150C meets all critical matching parameters and is therefore classified as an equivalent substitute for the TSF20H150C-S.

Engineering Selection Recommendations

TSF20H150C-S (Primary Part):

• Manufacturer: Taiwan Semiconductor Corporation
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Current Inventory: 994 Pcs New Original In Stock
• Forward voltage specification: 920 mV @ 10 A

STF20150C (Substitute Part):

• Manufacturer: SMC Diode Solutions
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Affected
• Current Inventory: 1251 Pcs New Original In Stock
• Forward voltage specification: 1.2 V @ 10 A

Both parts are Active products with ROHS3 compliance. The STF20150C operates at a higher forward voltage (1.2 V versus 920 mV) and exhibits higher reverse leakage current (150 µA versus 100 µA). These differences are within acceptable design tolerances for Schottky rectifier diodes in the 150 V, 10 A class. Selection between these parts is determined by application thermal budget, circuit efficiency requirements, and supply availability.

Frequently Asked Questions (FAQ)

Q: Can STF20150C directly replace TSF20H150C-S in existing circuit designs?

A: Yes. Both parts share identical voltage ratings (150 V), current capacity (10 A per diode), package configuration (TO-220-3 Full Pack, Isolated Tab), and operating temperature range (-55°C to 150°C). Pin-to-pin compatibility is maintained. The higher forward voltage of the STF20150C (1.2 V versus 920 mV) results in increased power dissipation and must be evaluated within the specific thermal design of the application.

Q: What is the difference in diode configuration between these parts?

A: The TSF20H150C-S is a single Schottky diode rated at 10 A. The STF20150C is a diode array configured as 1 Pair Common Cathode. In common cathode configuration, two diodes share a single cathode terminal. Circuit integration requirements determine which configuration is appropriate for the application.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). The TSF20H150C-S is REACH Unaffected, while the STF20150C is REACH Affected. Applications subject to REACH regulations must account for this distinction during component selection.

Q: How do the reverse leakage current specifications affect part selection?

A: The TSF20H150C-S specifies 100 µA reverse leakage at 150 V, while the STF20150C specifies 150 µA at the same conditions. Higher reverse leakage increases standby power consumption and heat generation. Applications with stringent leakage requirements or extended standby operation should prioritize the lower leakage specification.

Q: What packaging considerations apply to these through-hole components?

A: Both parts are supplied in Tube packaging and utilize the TO-220-3 Full Pack with Isolated Tab configuration. This isolated tab design permits independent thermal management of the diode junction. Through-hole mounting requires PCB via holes and solder connections compatible with standard wave or selective soldering processes.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Both parts meet the Fast Recovery specification (≤ 500ns, > 200mA). Switching frequency capability is equivalent between the two parts. Application-specific performance validation is required to confirm suitability for particular switching frequencies and duty cycles.
