Engineering Selection Recommendations

Both the GLL4735A-E3/97 and GLL4735A-E3/96 are Active product status components manufactured by Vishay General Semiconductor - Diodes Division. Selection between these parts is based on packaging and supply requirements rather than electrical performance.

The GLL4735A-E3/97 in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. The GLL4735A-E3/96 in Cut Tape format accommodates lower-volume production runs, manual assembly processes, or applications requiring smaller quantity procurement.

Both parts maintain identical electrical specifications, thermal operating range, and regulatory compliance. ROHS3 compliance and REACH Unaffected status apply uniformly across both variants. Moisture Sensitivity Level 1 (Unlimited) indicates no special storage or handling requirements for either part.

Frequently Asked Questions (FAQ)

Q: Can GLL4735A-E3/96 be used as a direct replacement for GLL4735A-E3/97?

A: Yes. Both parts are electrically identical with matching Zener voltage (6.2 V), power rating (1 W), impedance (2 Ohms), and operating temperature range (-65°C ~ 150°C). The only difference is packaging format: Tape & Reel versus Cut Tape. Circuit performance and reliability are unaffected by this substitution.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides components on tape segments, typically used for manual assembly, lower-volume production, or component kitting. Both formats contain the same component in the same DO-213AB MELF package.

Q: Are there any compliance or certification differences between these parts?

A: No. Both GLL4735A-E3/97 and GLL4735A-E3/96 carry identical ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level is 1 (Unlimited) for both parts, indicating no special environmental controls are required during storage or handling.

Q: Which part should be selected for high-volume production?

A: The GLL4735A-E3/97 in Tape & Reel format is optimized for high-volume automated assembly. Continuous reel feeding reduces component handling time and integrates directly with standard surface mount assembly equipment.

Q: Which part should be selected for low-volume or prototype applications?

A: The GLL4735A-E3/96 in Cut Tape format is suitable for low-volume production, prototype builds, or applications requiring smaller quantity purchases. Cut Tape format reduces waste and accommodates manual assembly processes.

Q: Do both parts have the same thermal performance?

A: Yes. Both parts operate across the identical temperature range of -65°C ~ 150°C with the same maximum power dissipation of 1 W. Thermal characteristics are determined by the component design and package type (DO-213AB MELF), which are identical for both variants.

Q: Is inventory availability a factor in part selection?

A: Inventory levels may influence procurement decisions. The GLL4735A-E3/96 (Cut Tape) currently has higher inventory availability (23,200 Pcs) compared to the GLL4735A-E3/97 (Tape & Reel, 648 Pcs). However, electrical and functional performance are identical regardless of packaging format or inventory status.
