Overview
The DDTC122TE-7-F is an obsolete NPN pre-biased transistor manufactured by Diodes Incorporated, housed in a compact SOT523 surface-mount package. This component integrates an NPN epitaxial planar die with a single built-in biasing resistor (R1) of 0.22kΩ connected to the base, while the second resistor position remains open. It is designed for high-reliability applications and meets AEC-Q101 automotive standards. The device operates within a supply voltage range up to 50V and supports a maximum output current of 100mA, featuring a gain-bandwidth product of 200MHz.
Feature Summary
- Integrates an NPN transistor with a single internal biasing resistor to simplify circuit design
- Constructed using epitaxial planar die technology for robust performance
- Qualified to AEC-Q101 standards ensuring suitability for high-reliability automotive environments
- Manufactured as a totally lead-free, halogen-free, and antimony-free green device
Applications
- Automotive electronic systems requiring AEC-Q101 qualified components
- General-purpose switching applications utilizing pre-biased configurations
- Digital logic interface circuits where simplified biasing networks are required
Procurement Notes
This specific part number is officially marked as obsolete and discontinued by the manufacturer. Verification of availability should focus on secondary market distributors or surplus suppliers rather than direct OEM channels. Engineers must confirm the authenticity of any sourced units through rigorous testing due to the discontinuation status. Replacement strategies should be initiated immediately to ensure long-term supply chain stability for production lines.
Selection Notes
Designers selecting this component should note it is an NPN type with only one internal resistor (R1 = 0.22kΩ) and an open R2 terminal. For complementary PNP functionality, the DDTA series is available. If two resistors are required, variants like the DDTC122LE offer both R1 and R2 values. The SOT523 package limits power dissipation to 150mW, necessitating careful thermal management in high-current switching scenarios.
Part Context
The DDTC122TE-7-F belongs to the DDTC family of pre-biased transistors from Diodes Incorporated. These devices combine bipolar junction transistors with internal resistors to reduce board space and assembly costs. The 'TE' suffix indicates the specific resistor configuration with R1 present and R2 open. The '-7-F' suffix denotes the standard reel packaging format used for automated surface-mount assembly processes.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the official documentation for this discontinued item. Engineers should evaluate equivalent NPN pre-biased transistors from other manufacturers that match the SOT523 footprint, 0.22kΩ base resistor value, and AEC-Q101 qualification requirements.
