Product details
Overview
DDA124EU-7 from Diodes Incorporated is a PNP pre-biased dual transistor in SOT363 package, featuring integrated 22 kΩ base-emitter and base-collector bias resistors. It delivers −30 mA output current per channel, −0.3 V typical VCE(sat) at −2.5 mA/−0.25 mA drive, and operates across −55°C to +150°C for automotive signal switching in body control modules.
For engineers reviewing the DDA124EU-7 datasheet, DDA124EU-7 pinout, DDA124EU-7 application, or DDA124EU-7 equivalent, key selection criteria include verified R1/R2 resistor matching (±30%), guaranteed AEC-Q101 qualification, thermal resistance of 625°C/W on FR-4, and confirmed −50 V VCBO rating under reverse bias conditions.
Technical Context
This dual PNP transistor integrates matched 22 kΩ bias resistors (R1 = R2) per channel to eliminate external base resistors in digital logic interface circuits. Each channel supports independent switching with −50 V collector-base breakdown and −50 mA maximum output current capability.
The device uses epitaxial planar die construction and is fully RoHS-compliant with halogen- and antimony-free "Green" molding compound. Its SOT363 package enables high-density PCB layouts while maintaining 200 mW total power dissipation (150 mW per element).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO | −50 V - Ensures safe operation in 24 V automotive systems with load dump transients |
| IO(max) | −30 mA per channel - Supports direct driving of small relays or LED indicators without external amplification |
| VCE(sat) | −0.3 V typ. at IC/IB = −2.5 mA/−0.25 mA - Minimizes conduction loss in low-voltage switching paths |
| R1 / R2 | 22 kΩ nominal, ±30% tolerance - Enables predictable turn-on threshold with <±20% R2/R1 ratio matching |
| PD | 200 mW total (150 mW per element) - Requires no heatsinking in ambient temperatures ≤70°C on standard FR-4 |
| TJ Range | −55°C to +150°C - Validated for under-hood automotive environments per AEC-Q101 stress testing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased dual PNP transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDA144EU-7-F | R1/R2 = 47 kΩ (vs. 22 kΩ), lower input current (−0.18 mA at VI = −5 V) | Better suited for high-impedance MCU outputs; reduced power consumption in battery-powered nodes | Select when driving from weak-sink GPIOs or optimizing standby current in always-on modules |
| DDA114YU-7-F | R1 = 10 kΩ, R2 = 47 kΩ - asymmetric bias network enabling higher gain (GL = 68) and −70 mA IO | Higher output current capability but tighter thermal constraints (requires derating above 60°C) | Choose for higher-current loads like small fans or buzzers where single-channel peak demand exceeds −30 mA |
Compared with DDA144EU-7-F and DDA114YU-7-F, DDA124EU-7 offers balanced input sensitivity and output drive for general-purpose automotive signal switching, with optimal thermal margin and resistor matching for cost-sensitive dual-load control.

FAQ
Is DDA124EU-7 qualified for automotive use?
Yes, DDA124EU-7 is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It meets PPAP requirements and supports change-controlled automotive applications, including body electronics and lighting control modules where reliability under thermal cycling and vibration is critical.
What is the maximum allowable junction temperature during operation?
The absolute maximum junction temperature is +150°C, with continuous operation supported from −55°C to +150°C. At 25°C ambient, full 200 mW power dissipation is allowed; derating begins linearly at 625°C/W above 25°C, reaching zero dissipation at 105°C ambient on standard FR-4 PCBs.
Can DDA124EU-7 replace discrete PNP transistors and resistors in existing designs?
Yes - it replaces two PNP BJTs and four bias resistors (two per channel) in standard inverter configurations. Pin compatibility with SOT363 layout and identical electrical thresholds enable drop-in replacement without schematic or layout changes in most cases.
Does DDA124EU-7 support 1.8 V logic input levels?
No - its VI(on) is −1.9 V (typ.) at IO = −5 mA, meaning reliable turn-on requires ≥2.5 V logic swing referenced to VCC. For 1.8 V systems, DDA113TU-7-F (1 kΩ R1) or DDA143TU-7-F (4.7 kΩ R1) provide lower-threshold alternatives.
