Product details
Overview
DDTC113ZE-7-F from Diodes Incorporated is an NPN pre-biased transistor in SOT523 package with integrated R1 = 1 kΩ and R2 = 10 kΩ bias resistors (R1 ≠ R2), VI(OFF) = 0.3 V, VI(ON) = 3.0 V (at IO = 20 mA), VO(ON) ≤ 0.3 V, and IOUT = 100 mA - used for digital logic-level switching in space-constrained load control circuits.
For engineers reviewing the DDTC113ZE-7-F datasheet, DDTC113ZE-7-F pinout, DDTC113ZE-7-F application, or DDTC113ZE-7-F equivalent, key selection criteria include input threshold voltage compatibility with 3.3 V/5 V microcontrollers, guaranteed saturation at low drive current, built-in resistor ratio stability, and SOT523 thermal performance under pulsed load conditions.
Technical Context
This device integrates a monolithic NPN transistor with two discrete on-die bias resistors (R1 = 1 kΩ, R2 = 10 kΩ) configured as a single-input inverter circuit, enabling direct interface with CMOS/TTL logic without external base resistors. Its R1 ≠ R2 topology ensures predictable turn-on behavior and stable DC current gain (GI = 33 min at IO = 5 mA).
Designed for low-power digital switching, it operates with VCC up to 50 V, supports IO(off) leakage < 0.5 μA at 50 V, and delivers fT = 250 MHz - confirming suitability for high-speed signal routing in portable and automotive body-control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VI(OFF) | 0.3 V - Ensures reliable cutoff when driven by 0 V or near-ground logic outputs. |
| VI(ON) | 3.0 V @ IO = 20 mA - Guarantees full saturation with standard 3.3 V GPIO without additional level-shifting. |
| VO(ON) | ≤ 0.3 V - Minimizes power loss and heat generation during active switching in battery-powered loads. |
| IOUT | 100 mA - Supports driving small relays, LEDs, or MOSFET gates directly from MCU pins. |
| GI (DC Current Gain) | 33 min @ IO = 5 mA - Provides consistent switching margin across temperature and process variation. |
| fT | 250 MHz - Validates capability for clean edge response in <100 ns pulse applications. |
| PD | 150 mW - Matches thermal limits of SOT523 on FR-4 PCB with minimal copper area. |
Pinout & Package
Package: SOT523 - ultra-small surface-mount plastic package (1.60 × 1.60 × 0.75 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.002 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Input reference node for bias network | Connected internally to R2; sets common return path for base current and output current. |

Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | R1 = 1 kΩ, R2 = 10 kΩ (±30% R1 tolerance, ±20% R2/R1 ratio) - eliminates 2 external resistors and layout error risk. |
| Guaranteed logic-compatible thresholds | VI(OFF) ≤ 0.3 V and VI(ON) ≥ 3.0 V - ensures interoperability with 3.3 V and 5 V digital families without ambiguity. |
| SOT523 footprint | 1.60 × 1.60 mm outline with 0.5 mm pitch - enables high-density placement in wearables and compact sensor nodes. |
| AEC-Q101 readiness | Manufactured in IATF 16949 certified facilities; PPAP-capable - supports automotive body electronics qualification paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDTC123YE-7-F | R1 = 2.2 kΩ, R2 = 10 kΩ; VI(ON) = 3.0 V @ IO = 20 mA but higher input impedance reduces drive current demand. | Better suited for 5 V logic systems where lower base current minimizes MCU loading. | Select when interfacing with older 5 V microcontrollers or when optimizing for lowest possible input current. |
| DDTC143XE-7-F | R1 = 4.7 kΩ, R2 = 10 kΩ; VI(ON) = 1.1 V @ IO = 20 mA - lower threshold enables use with 1.8 V logic families. | Enables direct interface with ultra-low-voltage MCUs (e.g., ARM Cortex-M0+ at 1.8 V supply) without level shifters. | Choose for next-generation battery-powered IoT nodes requiring sub-2 V input compatibility. |
Compared with DDTC123YE-7-F and DDTC143XE-7-F, the DDTC113ZE-7-F offers the lowest input resistance (1 kΩ), delivering highest base drive for robust saturation in noisy environments - ideal where margin against marginal logic levels is critical.

FAQ
What is the maximum continuous collector current rating for DDTC113ZE-7-F?
The absolute maximum rated output current is 100 mA, verified per datasheet DS30314 Rev.10–2 Section "Absolute Maximum Ratings". This value applies at TA = +25°C with proper PCB thermal relief; derating is required above 25°C per the published derating curve (1.5 mW/°C above 25°C).
Does DDTC113ZE-7-F require external base resistors?
No - it integrates R1 = 1 kΩ and R2 = 10 kΩ on-die bias resistors in a fixed R1 ≠ R2 configuration, forming a complete inverter circuit. No external resistors are needed for standard logic-level switching, confirmed by the schematic and test conditions in the Electrical Characteristics table.
Is DDTC113ZE-7-F qualified for automotive applications?
While not pre-qualified to AEC-Q101 in this specific marking, it is manufactured in IATF 16949 certified facilities and supports PPAP documentation. Diodes states that automotive-grade versions are available upon request - contact Diodes or Aetrix for change-controlled AEC-Q101 qualified variants.
What is the meaning of the 'N02' top-side marking on DDTC113ZE-7-F?
'N02' is the product type and date code marking per Diodes' specification: 'N' indicates year 2025, '02' denotes February 2025 production. This matches the Date Code Key in DS30314 Rev.10–2 page 3 and confirms traceability to manufacturing lot and cycle.
