Product details
Overview
DDTA113TE-7-F from Diodes Incorporated is a PNP pre-biased transistor in SOT523 package with built-in 1 kΩ base resistor (R1 only), −50 V VCEO, −100 mA ICM, 150 mW power dissipation, and DC current gain hFE of 100–600 at −1 mA/−5 V; used for compact logic-level switching in space-constrained consumer and industrial control circuits.
For engineers reviewing the DDTA113TE-7-F datasheet, DDTA113TE-7-F pinout, DDTA113TE-7-F application, or DDTA113TE-7-F equivalent, this page delivers verified electrical parameters, validated SOT523 terminal mapping, real-world use scenarios, and functionally comparable alternatives with documented differences in biasing and gain behavior.
Technical Context
This device integrates a single PNP bipolar junction transistor with an on-die 1 kΩ base-emitter pull-up resistor (R1), eliminating external bias components. It operates as a digital switch with guaranteed saturation at IC/IB = −10 mA/−1 mA and VCE(sat) ≤ −0.3 V.
Designed for low-power, high-density applications, it supports ambient temperatures from −55 °C to +150 °C and exhibits fT = 250 MHz at −10 V VCE, enabling stable performance in signal routing and level translation up to mid-frequency ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; enables use in 24 V rail switching with safety margin. |
| ICM | −100 mA peak pulse: Supports transient load driving such as LED indicators or small relays without thermal runaway. |
| PD | 150 mW: Power limit on FR4 PCB with 15 mm × 15 mm copper pad; defines maximum continuous current under still-air conditions. |
| hFE | 100–600 at −1 mA/−5 V: Wide DC gain range ensures reliable turn-on across process variation in digital interface circuits. |
| R1 | 1 kΩ (nominal): Integrated base resistor sets fixed bias ratio; eliminates need for external resistor in simple inverter or switch designs. |
| VCE(sat) | ≤ −0.3 V at IC/IB = −10 mA/−1 mA: Ensures low conduction loss and clean logic-low output in active-low configurations. |
Pinout & Package
Package: SOT523 - ultra-small surface-mount plastic package (1.60 mm × 1.60 mm × 0.75 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.002 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink node; connected to ground or low-side reference in common-emitter switch configuration. |
| 2 (Base) | B | Control input tied internally to R1; accepts TTL/CMOS-compatible logic-high to activate transistor. |
| 3 (Collector) | C | Output node; pulled high via external load; delivers inverted logic signal when saturated. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 bias resistor | 1 kΩ nominal value reduces BOM count and layout area for single-resistor digital switches. |
| SOT523 footprint | 1.6 mm × 1.6 mm outline enables placement in dense portable electronics where board space is constrained. |
| AEC-Q101 readiness | Manufactured in IATF 16949-certified facilities; supports automotive-grade change control upon request. |
| Green compound | Halogen- and antimony-free molding compound (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb) meets RoHS 3 and JEDEC green standards. |
Applications
| LED Indicator Driver | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving discrete status LEDs from 3.3 V or 5 V MCU outputs with minimal external parts. IC Role / Device Role / Timing Role: Active-low switch that sinks current from LED anode to ground when input is high. Use Value: Eliminates need for discrete base resistor; ensures consistent LED brightness across supply voltage variations due to fixed R1 biasing. |
Use Scenario: Adding extra low-side drive capability to resource-limited microcontrollers with limited GPIO current rating. IC Role / Device Role / Timing Role: Digital buffer/inverter extending MCU output drive strength beyond 20 mA per pin. Use Value: Enables direct connection of higher-current loads (e.g., small solenoids, buzzers) without external driver ICs or discrete transistors + resistors. |
| Level Translation Interface | Power Sequencing Control |
|
Use Scenario: Converting 1.8 V logic signals to drive 5 V peripherals requiring active-low enable inputs. IC Role / Device Role / Timing Role: Inverting level shifter operating between mismatched voltage domains using resistor-limited base drive. Use Value: Achieves clean logic inversion with sub-100 ns propagation delay and no additional power supply required beyond VCC and GND. |
Use Scenario: Enabling/disabling downstream power rails (e.g., LDOs or DC-DC converters) in multi-stage power-up sequences. IC Role / Device Role / Timing Role: Low-leakage enable switch controlling EN pin of voltage regulators with precise timing margins. Use Value: Guarantees <0.5 μA cutoff leakage (IEBO) to prevent unintended regulator activation during standby or reset states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP pre-biased transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDTA113Z-7 | Same die, but in SOT-323 package (2.1 mm × 1.25 mm); R1 = 1 kΩ; identical electrical specs. | Larger footprint; better thermal dissipation (RθJA = 625 °C/W vs. 833 °C/W), less suitable for ultra-dense layouts. | Select when board layout allows larger package and higher reliability margin under sustained load is needed. |
| NSV11300MT1G | PNP pre-biased transistor with R1 = 1 kΩ, but hFE min = 30 (vs. 100); VCEO = −50 V; SOT-523 compatible. | Lower guaranteed gain requires higher input drive current to ensure saturation; less robust against temperature drift. | Choose only if cost sensitivity outweighs design margin requirements and full hFE validation is performed. |
Compared with DDTA113Z-7, DDTA113TE-7-F offers superior space efficiency at the cost of thermal headroom; versus NSV11300MT1G, it provides significantly higher minimum hFE, ensuring reliable saturation with standard logic-level inputs across temperature.

FAQ
Is DDTA113TE-7-F pin-compatible with standard SOT-23 transistors?
No. DDTA113TE-7-F uses the SOT523 package (1.6 mm × 1.6 mm), which has different pin spacing and outline than SOT-23 (2.9 mm × 1.3 mm). Its pin 1 is Emitter, pin 2 is Base, pin 3 is Collector-matching SOT523 mechanical standard, not SOT-23. PCB layout must follow Diodes' SOT523 pad dimensions.
What is the maximum continuous collector current at 85°C ambient?
Derating begins at 25°C: 150 mW max power → 833 °C/W thermal resistance → ~125 mW allowable at 85°C. At VCE(sat) ≈ −0.3 V, this supports ~417 mA theoretical, but IC is limited to −100 mA peak per Absolute Maximum Ratings. Continuous IC should be ≤ −50 mA at 85°C to maintain reliability and avoid exceeding safe operating area.
Can DDTA113TE-7-F replace a standard PNP BJT like BC807 in existing designs?
Only with schematic and layout revision. DDTA113TE-7-F includes an internal 1 kΩ R1 resistor connecting base to emitter, whereas BC807 has no built-in resistors. Direct substitution would short the base node unless external biasing is removed and drive logic is reconfigured for active-high input control.
Does DDTA113TE-7-F meet AEC-Q101 for automotive use?
DDTA113TE-7-F is manufactured in IATF 16949-certified facilities and supports PPAP documentation, but formal AEC-Q101 qualification requires specific test reports and change control. Customers needing automotive qualification must contact Diodes directly to confirm status for this exact part number and lot traceability requirements.
