Product details
Overview
DDTA144GCA-7-F from Diodes Incorporated is a PNP pre-biased small-signal transistor in SOT-23 package, featuring a single built-in 47 kΩ bias resistor (R2 only), −50 V VCEO, −100 mA IC, −0.3 V VCE(sat) at −10 mA/−0.5 mA, and hFE = 68 (typ) at −5 mA/−5 V. It serves as a compact, AEC-Q101-qualified logic-level interface switch in automotive body control modules.
For engineers reviewing the DDTA144GCA-7-F datasheet, DDTA144GCA-7-F pinout, DDTA144GCA-7-F application, or DDTA144GCA-7-F equivalent, key selection criteria include verified R2-only bias topology, guaranteed −50 V breakdown ratings, SOT-23 thermal derating per FR4 layout, and RoHS-compliant green molding compound compliance per Date Code V9+.
Technical Context
This device implements a monolithic PNP bipolar junction transistor with an integrated emitter-grounded base bias network containing only R2 (47 kΩ), eliminating external base resistors for simplified high-side switching. Its −50 V VCBO/VCEO and −5 V VEBO support robust operation in 24 V automotive supply rails with transient margin.
The −0.3 V VCE(sat) at −10 mA collector current and −0.5 mA base drive enables low-loss switching in LED driver and sensor interface circuits, while the 250 MHz fT supports fast digital signal edge handling up to ~10 MHz toggle rates under defined bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Withstands 24 V system transients plus 26 V safety margin without breakdown. |
| IC (max) | −100 mA: Supports driving medium-current loads such as indicator LEDs or small relays. |
| VCE(sat) | −0.3 V @ −10 mA/−0.5 mA: Limits power loss to ≤3 mW during saturation, reducing thermal load on PCB. |
| hFE | 68 (typ) @ −5 mA/−5 V: Ensures reliable turn-on with standard microcontroller GPIO drive capability. |
| R2 | 47 kΩ ±30%: Provides fixed base bias for predictable switching thresholds without external components. |
| fT | 250 MHz: Enables use in pulse-width modulated (PWM) dimming circuits up to 10 MHz clock domains. |
| PD | 200 mW @ TA = 25°C: Requires derating above 25°C ambient per 625 °C/W RθJA on FR4 board. |
Pinout & Package
Package: SOT-23 (JEDEC TO-236AB), molded plastic case with UL 94V-0 flammability rating, moisture sensitivity level 1, and matte tin-plated Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Emitter (E) | Current sink node, internally connected to substrate ground reference | Provides low-impedance return path for collector current; must be tied to system ground or lowest potential rail. |
| Base (B) | Control input node connected to internal R2 resistor | Accepts TTL/CMOS-compatible logic-high signal to activate transistor; no external pull-up required. |
| Collector (C) | Switched output node, connected to load high-side | Drives load between VCC and collector; configured for high-side switching in PNP topology. |
Key Features
| Feature | Design Value |
|---|---|
| R2-only bias network | Single 47 kΩ resistor eliminates need for external base bias components, reducing BOM count and PCB area. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and lighting modules per stress test requirements. |
| Green compound packaging | Halogen- and antimony-free molding compound compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020D. |
| SOT-23 footprint | Standardized 3-pin surface-mount package compatible with automated pick-and-place and reflow soldering processes. |
Applications
| Automotive Door Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Controlling door lock actuators and interior lighting via 12 V/24 V supply rails with microcontroller GPIO. IC Role / Device Role / Timing Role: High-side PNP switch enabling load connection to positive rail while isolating MCU I/O from back-EMF.

Use Value: −0.5 μA ICBO limits quiescent current; −5 V VEBO prevents false triggering from noise on enable line. |
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 |
|---|---|---|---|
| DDTA124GCA-7-F | R2 = 22 kΩ (vs. 47 kΩ); hFE = 56 (vs. 68); same package and voltage ratings | Higher base current demand; better suited for lower-VCC or faster switching where gain margin is less critical | Select when tighter base drive control is needed or when operating at <12 V supply rails |
| DDTA114GCA-7-F | R2 = 10 kΩ; hFE = 30; identical thermal and voltage specs | Requires ~4.7× more base current than DDTA144GCA-7-F; optimized for high-speed digital switching over analog linearity | Choose for 5 V logic systems requiring rapid turn-on with minimal propagation delay |
Compared with DDTA124GCA-7-F and DDTA114GCA-7-F, DDTA144GCA-7-F delivers optimal balance of gain, bias current efficiency, and transient robustness for 12–24 V automotive and industrial interfaces where moderate speed and low standby loss are prioritized.

FAQ
What is the function of the "R2-only" configuration in DDTA144GCA-7-F?
The R2-only configuration means only a single 47 kΩ resistor connects the base to the emitter internally-no base-to-collector resistor (R1) is present. This topology simplifies circuit design by eliminating external bias components while maintaining predictable DC switching behavior and avoiding unintended latch-up in high-noise environments.
Is DDTA144GCA-7-F suitable for 24 V automotive applications?
Yes. Its −50 V VCEO and −50 V VCBO ratings exceed ISO 7637-2 load-dump transient requirements (up to +35 V), and its AEC-Q101 qualification confirms performance across −40°C to +125°C junction temperatures typical of under-hood environments.
How does the SOT-23 package affect thermal performance?
With RθJA = 625 °C/W on FR4 board using Diodes' recommended pad layout, the SOT-23 limits continuous power dissipation to 200 mW at 25°C ambient. Derating begins immediately above 25°C, reaching ~120 mW at 70°C ambient-adequate for intermittent switching but not sustained linear operation.
Can DDTA144GCA-7-F replace a standard PNP transistor like BC807?
No direct drop-in replacement: DDTA144GCA-7-F integrates R2 and lacks R1, so it cannot replicate the bias flexibility of discrete BC807. It replaces BC807 + external base resistor combinations, reducing component count but requiring verification of base drive compatibility and saturation voltage in the target circuit.
