Product details
Overview
DDTA114YE-7-F from Diodes Incorporated is a PNP pre-biased small-signal transistor in SOT523 package, featuring integrated bias resistors R1 = 10 kΩ and R2 = 47 kΩ (R1 ≠ R2), VCEO = −50 V, IC(max) = −70 mA, and DC current gain (hFE) = 68 at −10 mA/−5 V. It serves as a compact, AEC-Q101-qualified switch or level translator in automotive body control modules.
For engineers reviewing the DDTA114YE-7-F datasheet, DDTA114YE-7-F pinout, DDTA114YE-7-F application, or DDTA114YE-7-F equivalent, this page delivers verified electrical parameters, validated SOT523 terminal mapping, real-world switching use cases, and cross-reference alternatives with documented resistor ratio and gain differences.
Technical Context
This device integrates two precision bias resistors (R1 = 10 kΩ, R2 = 47 kΩ) directly into a PNP epitaxial planar transistor die, eliminating external base-resistor networks. Its asymmetric R1/R2 ratio enables optimized saturation and cutoff behavior for digital logic interfacing.
The SOT523 package supports high-density PCB layouts with 0.002 g mass and 833 °C/W junction-to-ambient thermal resistance on FR4. It operates across −55 °C to +150 °C and meets AEC-Q101 stress testing for automotive under-hood applications.
Key Specifications

| IC(max) | −70 mA - Continuous collector current rating; suitable for driving LED indicators or small relays. |
| R1 / R2 | 10 kΩ / 47 kΩ - Asymmetric internal bias network enabling fast turn-off and low standby leakage. |
| hFE | 68 @ −10 mA, −5 V - Confirmed DC current gain ensures reliable saturation with ≤0.5 mA input drive. |
| VIN(ON) | −1.3 V @ −1 mA - Input threshold voltage defining logic-high recognition level for 3.3 V or 5 V CMOS inputs. |
| PD | 150 mW - Power dissipation limit on standard FR4; requires no heatsink in typical low-duty-cycle switching. |
| fT | 250 MHz - Gain-bandwidth product confirms suitability for signal switching up to ~10 MHz edge rates. |

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 |
|---|---|---|---|
| DDTA114WE-7-F | R2 = 4.7 kΩ (vs. 47 kΩ); higher base current draw (−1.8 mA vs. −0.88 mA at −5 V) | Better suited for high-speed switching where faster turn-on is prioritized over low standby current | Select when driving capacitive loads or requiring sub-µs propagation delay; avoid in battery-powered always-on nodes. |
| DDTA124XE-7-F | R1 = 22 kΩ, R2 = 47 kΩ; lower input current (−0.88 mA → −0.36 mA at −5 V); hFE = 68 (same) | Optimized for ultra-low-power wake-up circuits and sensor interface stages with intermittent activity | Prefer for energy-sensitive applications such as tire pressure monitoring systems (TPMS) or wireless sensor nodes. |
Compared with DDTA114WE-7-F and DDTA124XE-7-F, DDTA114YE-7-F strikes a balance: its 10 kΩ/47 kΩ ratio delivers moderate input current (−0.88 mA), stable gain (68), and robust saturation (VCE(SAT) ≤ −0.3 V), making it ideal for general-purpose automotive and industrial digital switching where reliability and design simplicity are primary.

FAQ
What is the maximum operating temperature for DDTA114YE-7-F?
The DDTA114YE-7-F is rated for operation from −55 °C to +150 °C ambient temperature. This full range is validated per AEC-Q101 stress testing, including temperature cycling and high-temperature operating life, making it suitable for under-hood automotive environments and industrial enclosures without forced cooling.
Does DDTA114YE-7-F require an external base resistor?
No. DDTA114YE-7-F integrates both R1 (10 kΩ) and R2 (47 kΩ) internally, forming a complete bias network. This eliminates the need for external base resistors, reduces PCB footprint, and ensures matched thermal coefficients between R1 and R2 for stable switching thresholds across temperature.
How does the R1 ≠ R2 configuration improve performance over symmetric bias networks?
The asymmetric R1/R2 values (10 kΩ/47 kΩ) provide stronger base pull-down relative to pull-up, accelerating turn-off by rapidly removing stored charge. This results in shorter fall times and lower leakage in cutoff-key advantages for PWM-driven loads and battery-powered systems where quiescent current must be minimized.
Can DDTA114YE-7-F replace a standard PNP transistor like BC807 in existing designs?
Yes-but only if the circuit relies on external base biasing. DDTA114YE-7-F replaces both the transistor and its two base resistors. To retrofit, remove the external RB1 and RB2, connect the microcontroller GPIO directly to pin 2 (base), emitter to ground (pin 1), and load between VCC and collector (pin 3). Verify VIN(ON) and saturation voltage match system logic levels.
