SS22MHRSG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS22MHRSG is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Micro SMA package. This component operates at 20V DC reverse voltage with a 2A average rectified current rating and is suitable for fast recovery rectification circuits. The part is supplied in Tape & Reel (TR) packaging format.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. Alternative packaging formats may be required based on procurement availability or assembly process requirements.

Substitute Part Grouping Explanation

Substitution of the SS22MHRSG is determined by equivalence across the following critical parameters:

Reverse Voltage Rating: 20V DC maximum
Forward Current Capacity: 2A average rectified current
Forward Voltage Drop: 600 mV maximum at 2A
Recovery Speed: Fast recovery ≤ 500ns for currents > 200mA
Reverse Leakage Current: 150 µA at 20V
Junction Capacitance: 35 pF at 4V, 1MHz
Temperature Range: -55°C to 150°C junction operating range
Package Configuration: 2-SMD, Flat Lead in Micro SMA form factor
Mounting Technology: Surface mount compatible

The SS22M RSG maintains identical electrical specifications and mechanical compatibility with the SS22MHRSG. The primary difference is the packaging format: SS22M RSG is supplied in Cut Tape (CT) format rather than Tape & Reel (TR).

Engineering Selection Recommendations

Both the SS22MHRSG and SS22M RSG are active products manufactured by Taiwan Semiconductor Corporation with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional performance.

SS22MHRSG (Tape & Reel) is appropriate for high-volume automated assembly operations where continuous reel feeding is standard practice.

SS22M RSG (Cut Tape) is appropriate for lower-volume production runs, manual assembly processes, or applications where individual component handling is required.

Both parts maintain full compliance with ROHS3 and REACH regulations. Moisture sensitivity level MSL 1 indicates unlimited shelf life under standard storage conditions for both variants. The identical electrical performance ensures direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can SS22M RSG be used as a direct replacement for SS22MHRSG in production?

A: Yes. The SS22M RSG provides identical electrical performance and mechanical compatibility. The only difference is the packaging format (Cut Tape versus Tape & Reel). Assembly equipment compatibility must be verified based on your specific production line configuration.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical specifications for reverse voltage (20V), forward current (2A), forward voltage drop (600 mV @ 2A), recovery speed (≤ 500ns), reverse leakage current (150 µA @ 20V), and junction capacitance (35 pF @ 4V, 1MHz).

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, typically used for lower-volume assembly or manual handling. Both formats use the same Micro SMA package configuration.

Q: Do both parts have the same temperature operating range?

A: Yes. Both SS22MHRSG and SS22M RSG operate across the identical junction temperature range of -55°C to 150°C.

Q: Are compliance certifications identical for both parts?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings.

Q: Can these parts be mixed in the same assembly?

A: Yes, from an electrical and mechanical standpoint. However, assembly process compatibility must be evaluated based on your production equipment's ability to handle both Tape & Reel and Cut Tape formats.
