Frequently Asked Questions (FAQ)
Q: Can GDZ2V2B-E3-18 be used as a direct replacement for GDZ2V2B-HE3-08?
A: Yes. Both parts are parametric equivalents with identical electrical specifications, including 2.2 V zener voltage, 200 mW power rating, ±4% tolerance, and SOD-323 surface mount packaging. No circuit redesign or board layout modification is required.
Q: What is the difference between the two part numbers?
A: The part numbers differ in packaging configuration designators (HE3-08 versus E3-18), which relate to tape and reel specifications and supplier packaging formats. Electrical and mechanical performance are identical.
Q: Are both parts suitable for automotive applications?
A: The GDZ2V2B-HE3-08 carries explicit automotive-grade designation with AEC-Q101 qualification. The GDZ2V2B-E3-18 meets all equivalent electrical and compliance requirements. Confirmation of automotive qualification status for the E3-18 variant should be obtained from the manufacturer datasheet if automotive certification is a mandatory design requirement.
Q: What is the operating temperature range for these diodes?
A: Both parts operate across -55°C to 150°C, suitable for industrial and automotive temperature environments.
Q: Are these parts RoHS compliant?
A: Yes. Both GDZ2V2B-HE3-08 and GDZ2V2B-E3-18 are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations.
Q: What is the reverse leakage current specification?
A: Both parts specify 120 µA maximum reverse leakage current measured at 700 mV reverse bias voltage.
Q: Can these diodes be used interchangeably in existing PCB designs?
A: Yes. Both parts use identical SOD-323 (SC-76) surface mount packaging with matching pin configurations, footprints, and soldering requirements. No PCB redesign is necessary.
