Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZD27C47P R3G is determined by the following critical parameters:

• Zener Voltage (Vz): 47 V nominal
• Maximum Power Dissipation: 1 W or greater
• Package Type: DO-219AB surface mount
• Impedance (Zzt): 45 Ohms maximum
• Reverse Leakage Current: 1 µA @ 36 V
• Forward Voltage: 1.2 V maximum @ 200 mA
• Operating Temperature Range: Minimum -55°C to 175°C coverage
• Compliance: RoHS3 compliant

All identified substitute parts meet or exceed these electrical and mechanical specifications. Substitute parts BZD27C47P-E3-08, BZD27C47P-E3-18, and BZD27C47P-HE3-08 are manufactured by Vishay General Semiconductor - Diodes Division and maintain full electrical equivalence with the main part number.

Parameter Comparison

Engineering Selection Recommendations

BZD27C47P-E3-08 and BZD27C47P-E3-18: These Vishay parts are direct electrical equivalents with identical zener voltage, impedance, and leakage characteristics. Both are rated for 800 mW maximum power dissipation, which is lower than the main part's 1 W rating. These parts are suitable for applications where power dissipation does not exceed 800 mW. Both parts are RoHS3 compliant and maintain the same operating temperature floor of -65°C, providing enhanced low-temperature performance compared to the main part. BZD27C47P-E3-18 offers significantly higher inventory availability at 50,528 pieces.

BZD27C47P-HE3-08: This Vishay variant is electrically identical to BZD27C47P-E3-08 and additionally carries AEC-Q101 automotive qualification. This part is specified for automotive applications requiring formal qualification documentation. The 800 mW power rating applies to this variant as well. This part is suitable for automotive-grade circuit designs where component qualification is a contractual or regulatory requirement.

All substitute parts maintain full compliance with RoHS3 and REACH regulations. Selection between substitute candidates should be based on power dissipation requirements, automotive qualification necessity, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can BZD27C47P-E3-08, BZD27C47P-E3-18, or BZD27C47P-HE3-08 be used as direct replacements for BZD27C47P R3G?

A: Yes, all three substitute parts are electrically equivalent for applications where power dissipation does not exceed 800 mW. The main part is rated for 1 W; substitute parts are rated for 800 mW. If your circuit design requires the full 1 W dissipation capability, the substitute parts are not suitable. For applications operating below 800 mW, substitution is valid.

Q: What is the difference between BZD27C47P-E3-08 and BZD27C47P-E3-18?

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability: BZD27C47P-E3-18 has 50,528 pieces in stock compared to 6,100 pieces for BZD27C47P-E3-08. Both are packaged in Tape & Reel format and are suitable for high-volume production environments.

Q: When should BZD27C47P-HE3-08 be selected?

A: BZD27C47P-HE3-08 is specified for automotive applications requiring AEC-Q101 qualification. Select this part when your design is subject to automotive industry standards or when component qualification documentation is contractually required. The electrical performance is identical to the other Vishay variants.

Q: Are all substitute parts in the same package?

A: Yes, all substitute parts use the DO-219AB surface mount package, identical to the main part. All parts are compatible with the same PCB footprint and reflow soldering processes.

Q: What is the impact of the lower power rating on substitute parts?

A: Substitute parts are rated for 800 mW maximum dissipation versus 1 W for the main part. In applications where the zener diode dissipates less than 800 mW, this difference has no impact. For circuits designed to operate near or above 800 mW, the substitute parts may experience thermal stress and reduced reliability. Verify your circuit's actual power dissipation before substitution.

Q: Do substitute parts have different temperature operating ranges?

A: Substitute parts operate from -65°C to 175°C, compared to -55°C to 175°C for the main part. The substitute parts provide an extended low-temperature operating range of 10°C lower. Both ranges cover standard industrial and commercial temperature specifications.

Q: Are all parts RoHS3 compliant?

A: Yes, the main part and all substitute parts are RoHS3 compliant and REACH unaffected. All parts meet current environmental and regulatory requirements for electronic component manufacturing.
