DTB513ZE3TL

Overview

The DTB513ZE3TL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in an SOT-416 (EMT3) surface-mount package. It operates with a collector-emitter voltage of -300 mV and a continuous collector current of -500 mA. The device includes a typical input resistor of 1 kOhm and an emitter-base resistance of 10 kOhm, maintaining a resistor ratio of 10. Key electrical characteristics include a minimum DC current gain (hFE) of 140 at -100 mA and -2 V, a transition frequency of 260 MHz, and a power dissipation rating of 150 mW. It supports operating temperatures up to +150°C.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external components.
• Provides high-speed switching capabilities suitable for digital applications.
• Offers low saturation voltage for efficient power management.

Applications

• General-purpose digital switching circuits
• Interface circuits between logic gates and loads
• Driver stages for small-signal applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives as indicated in official documentation. Confirm availability through authorized distributors, noting that lead times may vary based on production schedules. Validate component authenticity via serial number tracking or manufacturer verification services before integration into final assemblies.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The SOT-416 package offers a compact footprint suitable for high-density PCB layouts. Consider the 1 kOhm input resistance value for compatibility with standard logic levels. Evaluate the 260 MHz transition frequency against the target application's switching speed requirements to ensure adequate performance margins.

Part Context

This part belongs to ROHM's series of Bias Resistor Built-in Transistors (BRBTs). These devices combine a single bipolar junction transistor with internal resistive networks to reduce board space and assembly costs. The DTB513 variant specifically utilizes a PNP structure with unequal bias resistors (R1/R2 = 1/10), distinguishing it from potential divider types where resistors are equal.

Replacement Considerations

Cross-reference with DTD513ZE3TL for NPN polarity alternatives within the same package family. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult ROHM's replacement guide for qualified equivalents that maintain identical mechanical dimensions and thermal characteristics.
