ASML-5822-BLKG RF Diode PIN Equivalent & Substitute Parts

Part Overview

The ASML-5822-BLKG is an RF Diode PIN manufactured by Broadcom Limited, combining PIN and Schottky diode functionality in a single SOT-323 package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates at peak reverse voltages of 60V and 22V with a maximum current rating of 1 A, designed for RF switching and attenuation applications requiring integrated PIN-Schottky architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ASML-5822-BLKG is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode type architecture (PIN + Schottky series connection vs. alternative topologies)
• Voltage rating compatibility (peak reverse voltage and forward voltage characteristics)
• Current handling capability (maximum current and average rectified current)
• Package form factor (SOT-323 / SC-70 surface mount compatibility)
• Operating temperature range
• Product status and availability

Substitution Logic: The three identified substitute parts represent different architectural approaches to RF diode functionality. The MADL-011021-14150T maintains the identical PIN + Schottky series connection topology as the main part, making it the closest functional equivalent. The 1PS70SB82,115 is a pure Schottky diode with reduced voltage and current ratings, suitable only for applications where PIN functionality is not required. The SKY16602-632LF is a single PIN diode with significantly different electrical characteristics and package configuration, applicable only to specific RF switching scenarios.

Parameter Comparison

Engineering Selection Recommendations

MADL-011021-14150T (Primary Substitute): This part maintains the PIN + Schottky series connection architecture identical to the ASML-5822-BLKG, providing the closest functional equivalence. The part is active and ROHS3 compliant with an elevated maximum junction temperature of 175°C. The 6-TDFN package requires PCB layout modification from the original SOT-323 footprint. This substitute is recommended for new designs or production transitions where package redesign is feasible.

1PS70SB82,115 (Package-Compatible Substitute): This part maintains the SOT-323 package form factor, eliminating PCB layout changes. However, it is a pure Schottky diode without PIN functionality, with significantly reduced voltage (15V) and current (30mA) ratings. This substitute is applicable only to applications where PIN diode characteristics are not functionally required and voltage/current requirements are within the reduced specifications. The part is active, ROHS3 compliant, and AEC-Q100 qualified for automotive applications.

SKY16602-632LF (Alternative Architecture): This part is a single PIN diode with 20V peak reverse voltage and 50mA maximum current in a 2-MLP package. It represents a fundamentally different architecture from the original part and is suitable only for RF switching applications where single PIN diode functionality is sufficient. The part is active and ROHS3 compliant but operates at a reduced maximum ambient temperature of 85°C.

Frequently Asked Questions (FAQ)

Q: Can the 1PS70SB82,115 directly replace the ASML-5822-BLKG in all applications?

A: No. The 1PS70SB82,115 is a Schottky-only diode without PIN functionality. It can only replace the ASML-5822-BLKG in applications where PIN diode characteristics are not required. Additionally, its voltage rating (15V) and current rating (30mA) are significantly lower than the original part (60V/22V, 1A). Verify that your application operates within these reduced specifications before substitution.

Q: What is the primary advantage of the MADL-011021-14150T?

A: The MADL-011021-14150T maintains the identical PIN + Schottky series connection topology as the ASML-5822-BLKG, providing true functional equivalence. It also offers a higher maximum junction temperature (175°C vs. 150°C). The trade-off is a package change from SOT-323 to 6-TDFN, requiring PCB layout modification.

Q: Why does the SKY16602-632LF have different package and power specifications?

A: The SKY16602-632LF is a single PIN diode architecture, not a PIN + Schottky combination. Its 2-MLP package and 12W power dissipation rating reflect its design for different RF applications. This part is suitable only for specific RF switching scenarios where single PIN diode functionality is appropriate.

Q: Are all substitute parts MSL Level 1?

A: Yes. All three substitute parts carry MSL Level 1 (Unlimited) moisture sensitivity classification, matching the original ASML-5822-BLKG. This ensures equivalent handling and storage requirements.

Q: What compliance certifications apply to these substitutes?

A: All substitute parts are ROHS3 compliant and REACH unaffected. The 1PS70SB82,115 carries additional AEC-Q100 automotive qualification. All parts are classified under ECCN EAR99 for export control purposes.

Q: Can I use the SKY16602-632LF as a direct replacement?

A: No. The SKY16602-632LF is a single PIN diode, not a PIN + Schottky combination. Its 20V voltage rating and 50mA current rating are also lower than the original part. This substitute is applicable only to applications where single PIN diode functionality is sufficient and voltage/current requirements are within specification.
