• Zener Voltage (Nominal): 27 V
• Tolerance: ±2%
• Maximum Power Dissipation: 150 mW
• Impedance (Maximum): 80 Ohms
• Reverse Leakage Current: 100 nA @ 18.9 V
• Forward Voltage: 900 mV @ 10 mA
• Operating Temperature Range: -55°C to 150°C
• Package / Case: SC-79, SOD-523
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

All substitute parts listed maintain identical electrical specifications and package requirements. Differences exist only in manufacturer identity, packaging format (Tape & Reel versus Cut Tape), and optional automotive-grade qualifications.

Parameter Comparison

Engineering Selection Recommendations

BZX584B27HE3-TP (Micro Commercial Co): This substitute is electrically and mechanically identical to the BZX584B27-TP. The primary distinction is AEC-Q101 automotive qualification, which certifies the component for automotive applications. Selection of this part is appropriate when automotive-grade reliability standards are required. Both parts are manufactured by Micro Commercial Co and supplied in Tape & Reel packaging. Inventory availability is significantly higher for this substitute (17,020 pcs versus 716 pcs).

BZX584B27 RSG (Taiwan Semiconductor Corporation): This substitute maintains all electrical parameters and operating characteristics identical to the BZX584B27-TP. The manufacturer differs (Taiwan Semiconductor Corporation), and the packaging format is Cut Tape & Digi-Reel® rather than standard Tape & Reel. The supplier device package designation is SOD-523F. This part is suitable for applications where manufacturer source diversification or alternative packaging formats are acceptable. Inventory availability is 9,030 pcs.

All three parts are ROHS3 compliant, REACH unaffected, and carry identical electrical specifications. Selection between them depends on inventory requirements, manufacturer preference, automotive qualification necessity, and packaging format compatibility with assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can BZX584B27HE3-TP be used as a direct replacement for BZX584B27-TP?

A: Yes. The BZX584B27HE3-TP is a parametric equivalent with identical electrical specifications, voltage rating, power dissipation, impedance, and operating temperature range. The only difference is the addition of AEC-Q101 automotive qualification. Both are surface mount SOD-523 packages suitable for identical PCB layouts.

Q: What is the significance of AEC-Q101 qualification on the BZX584B27HE3-TP?

A: AEC-Q101 is an automotive electronics qualification standard. The BZX584B27HE3-TP meets this standard, making it suitable for automotive applications where component reliability under automotive operating conditions is required. The BZX584B27-TP and BZX584B27 RSG do not carry this certification.

Q: Are there differences in the SOD-523 package between the BZX584B27-TP and BZX584B27 RSG?

A: Both parts use the SC-79, SOD-523 package. The BZX584B27 RSG specifies the supplier device package as SOD-523F, which is a variant designation. Both are surface mount packages with identical footprints and electrical performance.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is continuous reel packaging for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® is a hybrid format where components are supplied on cut tape segments or alternative reel formats. Selection depends on assembly equipment compatibility and order quantity requirements.

Q: Can I substitute the BZX584B27 RSG (Taiwan Semiconductor) for the BZX584B27-TP (Micro Commercial Co)?

A: Yes. All electrical parameters, voltage ratings, power dissipation, impedance, and operating temperature specifications are identical. The manufacturer differs, and packaging format differs. Both are ROHS3 compliant and REACH unaffected. Compatibility depends on your assembly equipment's ability to handle Cut Tape & Digi-Reel® packaging.

Q: Are all three parts suitable for the same circuit applications?

A: Yes. All three parts are 27 V, 150 mW Zener diodes with ±2% tolerance and identical electrical characteristics. They are suitable for identical voltage regulation, overvoltage protection, and reference voltage applications. Selection between them is based on inventory availability, manufacturer preference, automotive qualification requirements, and packaging format compatibility.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All three parts have MSL 1 (Unlimited), indicating unlimited shelf life without moisture control measures. No special storage or handling precautions are required.
