DTB113ZCHZGT116

Overview

The DTB113ZCHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors consisting of thin-film elements to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -500 mA. The device features a typical input resistance (R1) of 1 kOhm and an emitter-base resistance (R2) of 10 kOhm, yielding a typical resistor ratio of 10. It operates with a maximum power dissipation of 200 mW and supports a transition frequency up to 200 MHz. The component is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates thin-film bias resistors to eliminate the need for external input components in inverter circuits.
• Provides negative biasing at the input terminal to minimize parasitic effects.
• Simplifies circuit design by requiring only on/off condition settings for operation.

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose switching applications

Procurement Notes

Verify the specific suffix GT116 against official ROHM documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the procurement channel sources directly from authorized distributors to guarantee AEC-Q101 automotive grade authenticity. Cross-reference the full part number with the manufacturer's latest datasheet to confirm active status and compliance with current RoHS directives before finalizing orders.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The 1 kOhm input resistance suits standard logic interfaces, while the -50 V rating accommodates moderate voltage levels. Consider the 200 mW power dissipation limit for thermal management. Verify that the SOT-23-3 footprint aligns with the PCB layout constraints and that the 200 MHz frequency response meets the signal speed requirements of the target application.

Part Context

This part belongs to the DTx series of digital transistors from ROHM Semiconductor, which are designed as pre-biased transistors. The DTB113ZCHZGT116 specifically denotes the PNP variant within this family. It shares structural similarities with other models like DTD113ZCHZG but differs in polarity and specific electrical ratings. The series is characterized by the use of thin-film resistors for improved performance over traditional discrete resistor networks.

Replacement Considerations

The DTD113ZCHZG is documented as the complementary NPN type within the same product family. Direct substitution requires verifying polarity compatibility and ensuring the replacement part meets the -50 V and -500 mA requirements. Check if alternative PNP digital transistors from other manufacturers match the 1 kOhm/10 kOhm resistor ratio and SOT-23-3 package dimensions.
