MBR30100PTHC0G Equivalent & Substitute Parts

Part Overview

The MBR30100PTHC0G is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode with a maximum reverse voltage rating of 100 V and average rectified current of 30A per diode. The device is packaged in TO-247-3 through-hole configuration and is qualified to AEC-Q101 automotive standards. This part is currently active in production with 995 pieces in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed specifications for this diode rectifier category. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative sourcing is required while maintaining circuit performance and reliability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR30100PTHC0G are qualified based on the following critical parameters that must remain constant or equivalent:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Mounting Type: Through Hole
• Package / Case: TO-247-3
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Current Rating Consideration: The MBR30100PTHC0G operates at 30A average rectified current per diode. Substitute parts are grouped by their current rating capability. Parts rated at or above 30A maintain full electrical equivalence. Parts rated below 30A (15A, 20A) are listed as substitutes but operate at reduced current capacity and require circuit design verification for current derating.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and active product status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Full Current Rating):

The STPS61H100CW from STMicroelectronics is the direct equivalent substitute for the MBR30100PTHC0G. Both devices maintain identical electrical specifications: 100 V reverse voltage, 30A average rectified current per diode, 1 Pair Common Cathode configuration, and TO-247-3 through-hole packaging. The STPS61H100CW operates at a maximum junction temperature of 175°C compared to the MBR30100PTHC0G at 150°C, providing enhanced thermal margin. Both parts are ROHS3 compliant, MSL Level 1, and maintain active product status. The STPS61H100CW has 9230 pieces in stock inventory.

Reduced Current Rating Substitutes:

The STPS40H100CW (20A per diode) and STPS30H100CW (15A per diode) are available as substitutes when current derating is acceptable for the application. These parts maintain all other critical parameters: 100 V reverse voltage, Schottky technology, fast recovery speed, TO-247-3 packaging, and full compliance certifications. The STPS40H100CW provides 67% of the original current capacity with 2921 pieces in stock. The STPS30H100CW provides 50% of the original current capacity with 22238 pieces in stock inventory.

All substitute parts from STMicroelectronics maintain active product status and equivalent compliance certifications (ROHS3, MSL Level 1, REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can the STPS61H100CW be used as a direct replacement for the MBR30100PTHC0G?

A: Yes. The STPS61H100CW is a direct equivalent substitute. Both devices share identical electrical ratings (100 V, 30A per diode), diode configuration (1 Pair Common Cathode), technology (Schottky), and packaging (TO-247-3 through-hole). The STPS61H100CW operates at a higher maximum junction temperature (175°C vs. 150°C), which provides additional thermal headroom in the application.

Q: What is the difference between the STPS30H100CW, STPS40H100CW, and STPS61H100CW?

A: The primary difference is the average rectified current rating per diode. The STPS30H100CW is rated for 15A, the STPS40H100CW for 20A, and the STPS61H100CW for 30A. All three maintain the same 100 V reverse voltage rating, Schottky technology, fast recovery speed, and TO-247-3 packaging. Selection depends on the current requirements of the application circuit.

Q: Can I use the STPS30H100CW (15A) or STPS40H100CW (20A) in place of the MBR30100PTHC0G (30A)?

A: These parts are substitutes only when the application circuit can operate at reduced current levels. The STPS30H100CW provides 50% of the original current capacity, and the STPS40H100CW provides 67%. If the circuit requires the full 30A rating, these lower-rated devices are not suitable without circuit redesign or parallel configuration.

Q: Are all substitute parts compatible with the TO-247-3 footprint?

A: Yes. The MBR30100PTHC0G and all three substitute parts (STPS30H100CW, STPS40H100CW, STPS61H100CW) use the TO-247-3 through-hole package. Pin-to-pin compatibility is maintained, allowing direct board-level substitution without layout modifications.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, MSL Level 1 (Unlimited), REACH Unaffected, and classified as EAR99. The MBR30100PTHC0G carries AEC-Q101 automotive qualification; compliance status for substitute parts should be verified against specific application requirements.

Q: What is the difference in forward voltage between these devices?

A: The STPS40H100CW has a forward voltage of 730 mV at 20A, the STPS61H100CW has 790 mV at 30A, and the STPS30H100CW has 800 mV at 15A. These differences are typical for Schottky diodes at different current levels and may affect power dissipation calculations in high-current applications.

Q: Which substitute part has the best inventory availability?

A: The STPS30H100CW has the highest inventory with 22238 pieces in stock. The STPS61H100CW (direct equivalent) has 9230 pieces available. The STPS40H100CW has 2921 pieces in stock.
