Product details
Overview
DDTA113ZCA-7-F from Diodes Incorporated is a 50V PNP pre-biased transistor in SOT23 package, featuring integrated R1 = 1 kΩ and R2 = 10 kΩ bias resistors, −100 mA output current rating, −0.3 V saturation voltage at −20 mA, and DC current gain (hFE) of 33 at −10 mA collector current. It serves as a compact, surface-mount logic-level switch in automotive body control modules.
For engineers reviewing the DDTA113ZCA-7-F datasheet, DDTA113ZCA-7-F pinout, DDTA113ZCA-7-F application, or DDTA113ZCA-7-F equivalent, key selection criteria include input threshold voltage (−3.0 V at −20 mA), resistor tolerance (±30% on R1), thermal resistance (625 °C/W), and AEC-Q101 qualification status for automotive use.
Technical Context
This device integrates a PNP bipolar junction transistor with two monolithically embedded biasing resistors (R1 = 1 kΩ, R2 = 10 kΩ) to enable direct TTL/CMOS-compatible switching without external base drive components. Its −50 V VCBO rating supports robust operation in 12 V and 24 V automotive supply rails.
The SOT23 package delivers 200 mW power dissipation under standard FR4 mounting, with thermal resistance of 625 °C/W and operating temperature range from −55 °C to +150 °C - meeting requirements for under-hood and cabin electronics environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum allowable collector-emitter voltage before breakdown in common-emitter configuration. |
| IC(max) | −100 mA: Absolute maximum continuous collector current; defines upper limit for load switching capability. |
| VCE(sat) | −0.3 V at IC = −20 mA: Low saturation voltage ensures minimal power loss and heat generation during ON-state operation. |
| R1 / R2 | 1 kΩ / 10 kΩ: Fixed internal bias network enabling single-resistor logic interface and predictable turn-on behavior. |
| hFE | 33 at IC = −10 mA: Confirmed DC current gain determines required input drive current for target load current. |
| PD | 200 mW: Maximum power dissipation on standard FR4 PCB; sets thermal design boundary for ambient temperature derating. |
Pinout & Package
Package: SOT23 - surface-mount, 3-terminal plastic package with 0.915 mm nominal lead pitch, 2.40 mm body length, and 1.30 mm body width; RoHS-compliant matte tin plating; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal of PNP transistor | Connected to higher potential rail (e.g., battery +12 V); current flows out of this pin when device is ON. |
| 2 (Base) | Base node tied to R1–R2 junction | Internal connection point between bias resistors; accepts logic-level input signal referenced to emitter. |
| 3 (Collector) | Collector terminal of PNP transistor | Output node connected to load; sinks current toward ground or lower-potential return path. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 1 kΩ, R2 = 10 kΩ enables direct microcontroller GPIO drive without external resistors. |
| Automotive-grade construction | Fully qualified to AEC-Q101; manufactured in IATF 16949 certified facilities with PPAP support. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental compliance mandates. |
| SOT23 footprint compatibility | Standardized 3-pin layout allows drop-in replacement with other SOT23 pre-biased transistors in existing PCB designs. |

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 |
|---|---|---|---|
| DDTA123YCA-7-F | R1 = 2.2 kΩ, R2 = 10 kΩ; higher input impedance; Vin(on) = −3.0 V at −20 mA | Better suited for higher-impedance MCU outputs; slightly reduced drive strength at same input voltage | Select when driving from weak-sourcing GPIO or where lower base current consumption is critical |
| DDTA143XCA-7-F | R1 = 4.7 kΩ, R2 = 10 kΩ; Vin(on) = −2.5 V at −20 mA; hFE = 30 | Lower input threshold improves noise margin in noisy 12 V environments; reduced gain requires higher input current | Prefer for industrial control panels with long harness runs and EMI exposure |
Compared with DDTA123YCA-7-F and DDTA143XCA-7-F, DDTA113ZCA-7-F offers the lowest R1 value (1 kΩ), delivering strongest base drive and fastest switching in high-speed digital interfaces, while maintaining identical package, thermal performance, and automotive qualification.

FAQ
What is the absolute maximum input voltage for DDTA113ZCA-7-F?
The absolute maximum input voltage (Vin) is −10 V, measured between pin 1 (emitter) and pin 2 (base), per the Absolute Maximum Ratings table. Exceeding this may cause irreversible damage to the internal bias resistors or transistor junction.
Is DDTA113ZCA-7-F qualified for automotive applications?
Yes - DDTA113ZCA-7-F is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It supports PPAP documentation and is designated for automotive applications including body electronics, lighting, and power distribution systems.
How does the R1/R2 ratio affect switching behavior?
With R1 = 1 kΩ and R2 = 10 kΩ, the device provides strong base drive and fast turn-on (−3.0 V Vin(on) at −20 mA), making it ideal for low-impedance logic sources. The 10:1 ratio ensures stable biasing and prevents thermal runaway under varying temperature conditions.
Can DDTA113ZCA-7-F replace a discrete PNP transistor plus two resistors?
Yes - it replaces a standard PNP BJT (e.g., MMBT3906) plus 1 kΩ and 10 kΩ base resistors in a single SOT23 footprint. This reduces component count, improves matching between R1 and R2, and enhances reliability by eliminating solder joint failures associated with three separate parts.
