Product details
Overview
DDA114YH-7 from Diodes Incorporated is a PNP pre-biased dual small-signal surface-mount transistor in SOT563 package, featuring integrated 10kΩ and 47kΩ bias resistors, −50V VCEO, −70mA IO, and AEC-Q101 qualification for automotive reliability. It operates as a logic-level interface switch in low-power digital control circuits with rail-to-rail input voltage capability down to −0.3V.
For engineers reviewing the DDA114YH-7 datasheet, DDA114YH-7 pinout, DDA114YH-7 application, or DDA114YH-7 equivalent, key selection criteria include verified R1/R2 resistor values (10kΩ/47kΩ), guaranteed −0.3V VCE(SAT) at −5mA load, AEC-Q101 compliance, and SOT563 thermal performance (RθJA = 833°C/W).
Technical Context
This dual PNP transistor integrates two independent emitter-grounded switching elements sharing common base bias networks. Each channel uses discrete 10kΩ (R1) and 47kΩ (R2) resistors to enable direct TTL/CMOS logic-level drive without external components.
It delivers −70mA maximum output current per channel with −0.3V saturation voltage at IC/IB = −5mA/−0.25mA, and supports input voltages from −0.3V to −40V while maintaining <−0.5µA cutoff leakage under VCB = −50V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50V - Withstands up to −50V collector-emitter voltage before breakdown, enabling use in 24V automotive supply rails. |
| IO (Max) | −70mA - Supports driving moderate-current loads such as LED indicators or small relays without external amplification. |
| VCE(SAT) | −0.3V @ −5mA/−0.25mA - Ensures minimal power loss and heat generation during saturated switching operation. |
| R1 / R2 | 10kΩ / 47kΩ - Provides fixed base bias ratio optimized for reliable turn-on with standard logic high levels (≥−1.9V). |
| PD | 150mW - Limits continuous power dissipation to prevent thermal runaway on FR4 PCBs with recommended pad layout. |
| RθJA | 833°C/W - Specifies junction-to-ambient thermal resistance under JEDEC-standard mounting conditions. |
Pinout & Package
Package: SOT563 - 6-pin ultra-small surface-mount package with matte tin–annealed copper leadframe, UL 94V-0 rated molding compound, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter 1 | Common emitter connection for first PNP transistor; tied to ground reference in typical switch configuration. |
| 2 | Base 1 | Input node for first channel; internally connected to R1 (10kΩ) and R2 (47kΩ) network. |
| 3 | Collector 1 | Output node for first channel; sinks current when driven low at Base 1. |
| 4 | Collector 2 | Output node for second channel; electrically isolated from Collector 1 but shares same package thermal path. |
| 5 | Base 2 | Input node for second channel; identical internal R1/R2 topology as Pin 2. |
| 6 | Emitter 2 | Common emitter connection for second PNP transistor; independently routable from Emitter 1. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched 10kΩ/47kΩ resistor pair per channel eliminates need for external bias components and reduces board space. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules and body electronics requiring high-reliability operation from −55°C to +150°C. |
| SOT563 footprint | 0.005g weight and 2.2mm × 1.35mm outline enables dense placement in space-constrained modules like ADAS sensor nodes. |
| Low VCE(SAT) | −0.3V saturation voltage ensures <1.5mW conduction loss at −5mA, minimizing self-heating in always-on monitoring circuits. |
Applications
| Automotive Door Module Control | Industrial PLC Input Isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP pre-biased dual transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA114EH-7 | Same SOT563 package and R1/R2 values (10kΩ/10kΩ), but lower −50mA IO rating and −0.5V VCE(SAT). | Less suitable for ≥−60mA loads; acceptable where lower saturation voltage isn't critical. | Select when cost optimization outweighs need for lowest VCE(SAT) or highest current drive. |
| DDA143EH-7 | Different R1/R2 (4.7kΩ/4.7kΩ), higher −100mA IO, but −0.3V VCE(SAT) only at −20mA/−2mA drive condition. | Better for high-current switching but requires stronger base drive; less compatible with weak logic sources. | Prefer when interfacing with 5V-tolerant microcontrollers capable of sourcing >−2mA base current. |
Compared with DDA114EH-7 and DDA143EH-7, DDA114YH-7 uniquely balances −70mA drive capability, −0.3V saturation at modest base current, and precise 10kΩ/47kΩ bias ratio-making it optimal for automotive-grade logic-level translation where both efficiency and compatibility matter.

FAQ
What is the exact resistor configuration inside DDA114YH-7?
DDA114YH-7 contains two identical internal resistor networks: each channel has a 10kΩ resistor (R1) between base and input pin, and a 47kΩ resistor (R2) between base and emitter. This configuration sets a fixed base current ratio that ensures reliable saturation with logic-level inputs down to −1.9V.
Can DDA114YH-7 replace discrete PNP transistors in existing designs?
Yes-it replaces two discrete PNP transistors plus four external bias resistors. Designers must verify that the 10kΩ/47kΩ ratio matches required base drive, and that SOT563 layout accommodates its 2.2mm × 1.35mm footprint and thermal pad requirements per Diodes' recommended land pattern.
Is DDA114YH-7 suitable for 12V automotive battery monitoring?
Yes-its −50V VCEO rating exceeds typical automotive transients (ISO 7637-2 Pulse 1: −100V, Pulse 2a: +100V), and AEC-Q101 qualification covers temperature cycling, humidity, and mechanical shock testing required for under-hood deployment.
Does DDA114YH-7 support bidirectional signal routing?
No-it functions exclusively as a unidirectional PNP sink switch. The internal diode structure and fixed bias network prevent reverse current flow or AC coupling; it is not designed for analog signal switching or bidirectional bus termination.
