Substitute Part Grouping Explanation

Substitute parts for the BZX584B13 are qualified based on matching the following critical parameters:

Voltage - Zener (Nominal): 13 V
Power - Maximum: 150 mW
Tolerance: ±2%
Impedance (Maximum): 30 Ohms
Current - Reverse Leakage @ Vr: 100 nA @ 8 V
Operating Temperature Range: -55°C to 150°C (TJ)
Mounting Type: Surface Mount
Package / Case: SC-79, SOD-523 or SOD-523F

All identified substitutes maintain these electrical specifications and physical form factors, ensuring functional equivalence in circuit applications. Packaging format variations (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical performance and represent alternative supply chain options.

Engineering Selection Recommendations

All three parts—BZX584B13, BZX584B13 RSG, and BZX584B13HE3-TP—are active-status zener diodes with identical electrical specifications and are suitable for direct substitution in applications requiring a 13 V, 150 mW surface mount zener diode.

BZX584B13 RSG (Taiwan Semiconductor Corporation) differs from the main part only in packaging format, supplied as Cut Tape & Digi-Reel rather than Tape & Reel. This substitute is appropriate for applications where alternative packaging logistics are acceptable. Moisture Sensitivity Level is rated 1 (Unlimited).

BZX584B13HE3-TP (Micro Commercial Co) provides an automotive-grade alternative with AEC-Q101 qualification. This part is suitable for applications requiring automotive-level reliability and traceability. Packaging is supplied as Tape & Reel, matching the main part format. Moisture Sensitivity Level is rated 1 (Unlimited). Forward voltage specification (900 mV @ 10 mA) is provided as additional characterization data.

Selection between these parts depends on supply chain availability, packaging requirements, and whether automotive-grade qualification is mandated by application specifications.

Frequently Asked Questions (FAQ)

Q: Can BZX584B13 RSG be used as a direct replacement for BZX584B13?

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (13 V, 150 mW, ±2% tolerance, 30 Ohms impedance, 100 nA reverse leakage). The only difference is packaging format: BZX584B13 RSG is supplied in Cut Tape & Digi-Reel format while BZX584B13 is supplied in Tape & Reel format. Electrical performance and physical package dimensions are equivalent.

Q: What is the difference between BZX584B13HE3-TP and the other substitutes?

A: BZX584B13HE3-TP is manufactured by Micro Commercial Co and carries automotive-grade qualification (AEC-Q101). All electrical parameters match the main part exactly. This part is appropriate for applications requiring automotive reliability standards. Packaging is Tape & Reel format, matching the main part.

Q: Are all three parts RoHS3 compliant?

A: Yes. BZX584B13, BZX584B13 RSG, and BZX584B13HE3-TP are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affects supply chain logistics and handling only. Electrical specifications and performance are identical across all packaging formats.

Q: Can BZX584B13HE3-TP be used in non-automotive applications?

A: Yes. BZX584B13HE3-TP meets or exceeds the electrical specifications of the main part and is suitable for any application requiring a 13 V, 150 mW surface mount zener diode. Automotive qualification is an additional feature that does not restrict use in other applications.

Q: What is the operating temperature range for all substitute parts?

A: All three parts operate across the temperature range -55°C to 150°C (TJ), providing equivalent thermal performance for applications requiring extended temperature operation.

Q: Are moisture sensitivity levels specified for all parts?

A: Moisture Sensitivity Level (MSL) 1 (Unlimited) is specified for BZX584B13 RSG and BZX584B13HE3-TP. This rating indicates no moisture sensitivity restrictions during storage and handling.
