Substitute Part Grouping Explanation

Substitution of Zener diodes within the PLZ13 series is determined by electrical parameter equivalence across the following criteria:

Primary Substitution Parameters:

Zener voltage nominal value: 13 V
Tolerance specification: ±3%
Maximum power dissipation: 500 mW
Package type: DO-219AC (microSMF)
Mounting configuration: Surface Mount
Maximum impedance: 14 Ohms
Reverse leakage current: 200 nA @ 10 V
Operating temperature rating: 150°C

Secondary Considerations:

Forward voltage specification (Vf @ 10 mA): 900 mV or 800 mV
Packaging format: Cut Tape (CT), Tape & Reel (TR), or Digi-Reel®
Automotive qualification (AEC-Q101) where applicable

All substitute parts maintain identical core electrical specifications and package geometry, ensuring direct functional replacement in circuit applications. Packaging format differences do not affect electrical performance and are selected based on procurement and assembly requirements.

Engineering Selection Recommendations

PLZ13A-G3/H: Functionally equivalent to PLZ13C-G3/H with identical electrical specifications. Supplied in Tape & Reel (TR) format for automated assembly processes. Suitable for high-volume production environments requiring continuous reel packaging.

PLZ13B-G3/H: Functionally equivalent with forward voltage specification of 800 mV @ 10 mA, compared to 900 mV for the main part. All other electrical parameters remain identical. Supplied in Tape & Reel (TR) format. Highest inventory availability (23,135 pcs) among substitute options.

PLZ13C-HG3_A/H: Functionally equivalent to PLZ13C-G3/H with additional AEC-Q101 automotive qualification. Supplied in Cut Tape (CT) and Digi-Reel® formats. Suitable for automotive applications requiring formal qualification documentation. Identical electrical specifications to the main part.

All substitute parts are active products with RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1). Selection between substitutes is based on packaging format requirements, inventory availability, and automotive qualification needs rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can PLZ13A-G3/H replace PLZ13C-G3/H in existing designs?

A: Yes. Both parts share identical zener voltage (13 V), tolerance (±3%), power rating (500 mW), impedance (14 Ohms), reverse leakage current (200 nA @ 10 V), and operating temperature (150°C). The primary difference is packaging format: PLZ13A-G3/H is supplied in Tape & Reel (TR) while PLZ13C-G3/H is supplied in Cut Tape (CT). Electrical performance is equivalent.

Q: What is the difference between PLZ13B-G3/H and PLZ13C-G3/H?

A: The forward voltage specification differs: PLZ13B-G3/H specifies 800 mV @ 10 mA while PLZ13C-G3/H specifies 900 mV @ 10 mA. All other electrical parameters are identical. Both are supplied in Tape & Reel (TR) format. The lower forward voltage of PLZ13B-G3/H may be advantageous in applications sensitive to forward voltage characteristics.

Q: Is PLZ13C-HG3_A/H suitable for automotive applications?

A: Yes. PLZ13C-HG3_A/H carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. It maintains identical electrical specifications to PLZ13C-G3/H and is supplied in Cut Tape (CT) and Digi-Reel® formats.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts in this substitution group (PLZ13C-G3/H, PLZ13A-G3/H, PLZ13B-G3/H, and PLZ13C-HG3_A/H) are RoHS3 compliant and REACH unaffected.

Q: What packaging formats are available for these Zener diodes?

A: PLZ13C-G3/H and PLZ13C-HG3_A/H are supplied in Cut Tape (CT) format. PLZ13A-G3/H and PLZ13B-G3/H are supplied in Tape & Reel (TR) format. PLZ13C-HG3_A/H is also available in Digi-Reel® format. Selection depends on assembly process requirements and volume specifications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the PCB design accommodates the selected packaging format. All parts use the same DO-219AC (microSMF) surface mount package and have identical pin configurations. Tape & Reel (TR) format is standard for automated pick-and-place assembly, while Cut Tape (CT) is suitable for manual or lower-volume assembly processes.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All parts in this group have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage or handling.
