Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMBZ20VAL-7 are grouped based on electrical parameter equivalence and mechanical compatibility. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 17V
• Voltage - Breakdown (Min): 19V
• Voltage - Clamping (Max) @ Ipp: 28V
• Current - Peak Pulse (10/1000µs): 1.4A
• Power - Peak Pulse: 40W
• Unidirectional Channels: 2
• Type: Zener

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Product Status: Active

Substitute parts are differentiated by manufacturer, packaging format (Cut Tape vs. Tape & Reel), and operating temperature range specifications. All identified substitutes maintain identical electrical performance and package compatibility with the main part.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the MMBZ20VAL-7. Selection among substitutes is determined by application-specific requirements:

MMBZ20VAL,215 (Nexperia USA Inc.): Direct electrical equivalent with identical voltage and current specifications. Supplied in Tape & Reel packaging format. Maintains AEC-Q101 automotive qualification. Operating temperature range -55°C to 150°C. Suitable for applications requiring Nexperia component sourcing or Tape & Reel packaging format.

MMBZ20VALT1G (onsemi): Electrical equivalent with identical voltage and current specifications. Supplied in Tape & Reel packaging format. Operating temperature range -55°C to 150°C. Highest inventory availability (4,427,300 pcs). Suitable for high-volume production requirements. Note: AEC-Q101 qualification not specified in provided data.

SZMMBZ20VALT1G (onsemi): Electrical equivalent with identical voltage and current specifications. Supplied in Cut Tape & Digi-Reel® packaging format, matching the main part packaging. Maintains AEC-Q101 automotive qualification. Operating temperature range -55°C to 150°C. Suitable for applications requiring Cut Tape packaging format and automotive qualification.

SZMMBZ20VALT3G (onsemi): Electrical equivalent with identical voltage and current specifications. Supplied in Tape & Reel packaging format. Maintains AEC-Q101 automotive qualification. Operating temperature range -55°C to 150°C. Suitable for applications requiring Tape & Reel packaging format with automotive qualification.

All substitutes are Active product status with ROHS3 compliance and REACH Unaffected designation.

Frequently Asked Questions (FAQ)

Q: Can MMBZ20VAL,215 be used as a direct replacement for MMBZ20VAL-7?

A: Yes. Both parts share identical electrical parameters (17V reverse standoff, 19V breakdown minimum, 28V clamping maximum, 1.4A peak pulse current, 40W peak power) and are packaged in SOT-23-3 (TO-236-3) surface mount configuration. The primary difference is packaging format: MMBZ20VAL,215 is supplied in Tape & Reel format while MMBZ20VAL-7 is supplied in Cut Tape & Digi-Reel® format.

Q: What is the difference between SZMMBZ20VALT1G and SZMMBZ20VALT3G?

A: Both parts are electrically identical with matching voltage and current specifications. The difference is packaging format: SZMMBZ20VALT1G is supplied in Cut Tape & Digi-Reel® format, while SZMMBZ20VALT3G is supplied in Tape & Reel format. Both maintain AEC-Q101 automotive qualification.

Q: Are all substitute parts AEC-Q101 qualified?

A: MMBZ20VAL,215, SZMMBZ20VALT1G, and SZMMBZ20VALT3G are specified as AEC-Q101 qualified. MMBZ20VALT1G does not have AEC-Q101 qualification specified in the provided data. For automotive applications requiring AEC-Q101 compliance, use MMBZ20VAL,215, SZMMBZ20VALT1G, or SZMMBZ20VALT3G.

Q: What is the operating temperature difference between the main part and substitutes?

A: MMBZ20VAL-7 operates from -65°C to 150°C (junction temperature). All substitute parts operate from -55°C to 150°C. The main part provides 10°C additional low-temperature operating range. For applications requiring operation below -55°C, the MMBZ20VAL-7 is required.

Q: Can I use MMBZ10VAL,215 as a substitute?

A: No. MMBZ10VAL,215 has different electrical specifications: 6.5V reverse standoff (maximum), 9.5V breakdown minimum, and 14.2V clamping maximum. These parameters are not compatible with applications designed for the MMBZ20VAL-7 17V/28V specifications.

Q: Which substitute has the highest inventory availability?

A: MMBZ20VALT1G (onsemi) has the highest inventory with 4,427,300 pieces in stock, followed by SZMMBZ20VALT3G with 25,100 pieces and SZMMBZ20VALT1G with 20,400 pieces.

Q: Are all parts ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part MMBZ20VAL-7.
