1PGSMA180Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 1PGSMA180Z is a surface mount Zener diode rated for 180 V nominal voltage with 1.25 W maximum power dissipation in a DO-214AC (SMA) package. This component is manufactured by Taiwan Semiconductor Corporation and maintains Active product status. Substitute parts become necessary when the primary part number is unavailable from distribution channels or when alternative packaging formats are required for manufacturing processes. The electrical and mechanical specifications of substitute parts must match the original component to ensure functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1PGSMA180Z is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Zener (Nom): 180 V
• Tolerance: ±5%
• Power - Max: 1.25 W
• Impedance (Max): 1200 Ohms
• Current - Reverse Leakage @ Vr: 1 µA @ 136.8 V
• Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 200 mA
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Equivalence Criteria:

• Package / Case: DO-214AC (SMA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain identical electrical performance and environmental compliance specifications. Packaging format (Tape & Reel versus Cut Tape) represents the only variable among equivalent parts and does not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

1PGSMA180Z (Main Part - Active Status)

The 1PGSMA180Z is the primary specification with Active product status. This part number is suitable for new designs and ongoing production where standard-grade Zener diodes meet application requirements. Tape & Reel packaging is standard for high-volume automated assembly processes.

1PGSMA180Z R3G (Substitute - Discontinued)

This part maintains identical electrical specifications and RoHS3 compliance. The Cut Tape packaging format differs from the main part and is suitable for lower-volume or manual assembly operations. Product discontinuation at DiGi Electronics indicates limited future availability; use only when inventory is confirmed available from alternative distribution channels.

1PGSMA180ZHR3G (Substitute - Discontinued, Automotive Grade)

This part is qualified to AEC-Q101 automotive standards and carries Automotive grade designation. Electrical specifications remain identical to the main part. Tape & Reel packaging matches the main part format. Product discontinuation at DiGi Electronics indicates limited future availability. Selection of this part is appropriate only for automotive applications requiring AEC-Q101 qualification and when inventory availability is confirmed.

Frequently Asked Questions (FAQ)

Q: Can 1PGSMA180Z R3G be used as a direct replacement for 1PGSMA180Z?

A: Yes. Both parts share identical electrical specifications (180 V nominal, 1.25 W power rating, ±5% tolerance, operating temperature -55°C to 175°C) and mechanical compatibility (DO-214AC SMA package, surface mount). The only difference is packaging format: Cut Tape versus Tape & Reel. Electrical performance and circuit functionality are equivalent.

Q: What is the difference between 1PGSMA180Z and 1PGSMA180ZHR3G?

A: Both parts have identical electrical specifications and RoHS3 compliance. The 1PGSMA180ZHR3G carries Automotive grade designation and AEC-Q101 qualification, making it suitable for automotive applications. Packaging format is identical (Tape & Reel). Selection depends on application requirements and automotive qualification necessity.

Q: Why are some substitute parts marked as Discontinued at DiGi Electronics?

A: Product discontinuation at a specific distributor does not indicate functional obsolescence. Discontinued status reflects distribution channel decisions and inventory management. Substitute parts remain electrically and mechanically equivalent. Availability must be confirmed through alternative distribution channels before design implementation.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly process compatibility. Electrical specifications, performance characteristics, and circuit functionality remain identical regardless of packaging format. Selection should be based on manufacturing process requirements and assembly equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status, identical to the main part. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can 1PGSMA180ZHR3G be used in non-automotive applications?

A: Yes. The 1PGSMA180ZHR3G meets or exceeds all electrical and mechanical specifications required for standard applications. AEC-Q101 qualification represents an additional quality assurance level and does not restrict use in non-automotive circuits. Selection can be based on availability and cost considerations.
