1. Overall Purpose:

️· This document outlines the packaging requirements for diodes manufactured by the company. It covers:
- Ammo (tape & reel) specifications.
- Inner box requirements.
- Labeling requirements (LRC labels and environmental labels).
- Cartoon (outer box) quantities and dimensions.
- Tape dimensions.

2. Key Components & Specifications:

️· Tape & Reel (Ammo) Specifications:
- Several tape sizes are specified: 26, 35, 40, 42, and 52. Note that the "52" size specifically refers to the DO-201AD package.
- Tape Width (W), Pitch (P), Lead Lengths (L1-L2), Height (H), Length (Z), Radius (R), and Thickness (T) are all defined with tolerances.
- Lead lengths (L1-L2) are designed to be less than 1.0mm.
- Tape Thickness (T) must be greater than 3.5mm.
- Red and white tapes have a thickness of 0.05mm.
- Lead wire should extend 20-40cm.
- Red tape indicates the negative terminal (cathode), and white tape indicates the positive terminal (anode).

️· Inner Box Specifications:
- Dimensions for ammo are given for T52, T42, and T26.

️· Labeling Requirements:
- LRC labels are used, with specific information included like the part number, peak repetitive voltage, average output current, quantity, and production date.
- Environmental labels are also required.

️· Cartoon (Outer Box) Specifications:
- Dimensions for cartoon boxes are provided.
- Quantity per cartoon varies based on the tape size (ammo) and specific diode type. The document provides the number of diodes per ammo and outer box for several diode types and tape sizes.

️· Update Record: This section tracks revisions to the specification.

3. Important Notes:

️· "52 Tape #" designation: Specifically references the DO-201AD package and has tighter specifications.
️· Material & Color: Red and white tapes are specified with a thickness of 0.05mm, ensuring consistent color and thickness.
️· Lead Wire: The length of the lead wires extending from the tape is controlled (20-40cm).
️· Polarity: The tape color indicates the diode polarity, crucial for proper circuit assembly.
️· Environmental Compliance: The inclusion of "environmental labels" indicates a requirement for RoHS or other environmental compliance.

4. General Interpretation:

This is a fairly detailed packaging specification designed to ensure consistency and quality control throughout the manufacturing and distribution process. The tight tolerances on the tape dimensions, along with the labeling and outer box quantities, are meant to support automated handling and accurate inventory management.
