Overview
The DDTC122TE-7 is an obsolete NPN pre-biased transistor manufactured by Diodes Incorporated. It features a single configuration with built-in biasing resistors, specifically R1 at 0.22 kOhms and an open circuit for R2. The device operates within a collector-emitter voltage range of up to 50 V and supports a continuous collector current of 100 mA. Power dissipation is rated at 150 mW, with an operating temperature range spanning from -55°C to +150°C. It utilizes the SOT-523 surface-mount package.
Feature Summary
- Epitaxial planar die construction
- Built-in biasing resistors
- Totally lead-free and fully RoHS compliant
- Qualified to AEC-Q101 standards
Applications
- High reliability electronic circuits
- Automotive applications requiring AEC-Q101 compliance
- Surface mount assembly processes
Procurement Notes
This component is officially marked as obsolete and discontinued by the manufacturer. Verification of availability should focus on finding direct replacement part numbers or checking for surplus stock through authorized distributors. Confirm that any substitute components meet the original electrical specifications and package requirements before integration into designs.
Selection Notes
Designers should note that this specific part number is no longer in production. Selection of alternative components must ensure compatibility with the required 50 V collector-emitter voltage and 100 mA current limits. Verify that replacement devices offer similar input resistance characteristics and fit within the thermal constraints defined by the 150 mW power dissipation rating.
Part Context
The DDTC122TE-7 belongs to the DDTC (LO-R1) E series of NPN pre-biased transistors produced by Diodes Incorporated. This series includes complementary PNP types and variants with different resistor configurations. The product line emphasizes green manufacturing practices and automotive-grade reliability standards.
Replacement Considerations
Direct substitutes include DDTC122LE-7-F, DDTC142JE-7-F, and DDTC142TE-7-F. These alternatives share the same package and general electrical ratings but differ in internal resistor values.
