DTD513ZETL

Overview

The DTD513ZETL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates bias resistors with a typical base resistance (R1) of 1 kOhm and emitter-base resistance (R2) of 10 kOhm. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 12 V, continuous collector current of 500 mA, and power dissipation of 150 mW. The device features a minimum DC current gain (hFE) of 140 at 100 mA and 2 V, with a transition frequency of 260 MHz. It operates within a temperature range up to +150°C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities suitable for digital logic applications.
• Offers low saturation voltage for efficient power management.

Applications

• General-purpose digital switching circuits
• Interface between microcontrollers and peripheral devices
• Level shifting and buffer applications

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as standard quantities may vary. Ensure the procurement channel provides original manufacturer documentation to validate RoHS compliance and authenticity. Cross-reference the part number with official ROHM databases to confirm current production status and availability constraints before finalizing orders.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. The 1k/10k resistor ratio is suitable for standard TTL or CMOS logic interfaces. Consider the 12V voltage rating and 500mA current capacity against load requirements. Verify thermal management needs given the 150mW power dissipation limit in the small SOT-416 package.

Part Context

This part belongs to the DTD513ZE series of pre-biased transistors from ROHM. It is functionally similar to other variants like DTD513ZE3TL but differs in packaging and taping specifications. The EMT3 package designation corresponds to the industry-standard SOT-416 form factor, ensuring compatibility with existing footprints designed for this family.

Replacement Considerations

Direct substitutes include DTC113E and DTC114E series parts, though resistor values and current ratings differ. For identical electrical characteristics, verify equivalent NPN digital transistors with 1k/10k bias ratios and compatible VCEO ratings. Always check pinout compatibility and thermal performance before swapping components.
