Product details
Overview
DDTB113ZC-7-F from Diodes Incorporated is a PNP pre-biased transistor in SOT23 package, featuring integrated 1 kΩ and 10 kΩ bias resistors, −40 V collector-emitter breakdown voltage, 56 minimum DC current gain (hFE), and −500 mA continuous output current capability. It functions as an integrated switch for low-power digital interface and level-shifting circuits in automotive body control modules.
For engineers reviewing the DDTB113ZC-7-F datasheet, DDTB113ZC-7-F pinout, DDTB113ZC-7-F application, or DDTB113ZC-7-F equivalent, key selection criteria include verified R1/R2 resistor values (1 kΩ/10 kΩ), guaranteed VCE(sat) ≤ −0.3 V at −50 mA, confirmed AEC-Q101 qualification status, and SOT23 thermal resistance of 625 °C/W on FR4 board.
Technical Context
This device integrates two precision biasing resistors (R1 = 1 kΩ, R2 = 10 kΩ) directly into a monolithic PNP epitaxial planar transistor die, eliminating external base-resistor placement and reducing PCB footprint. Its −0.3 V saturation voltage at −50 mA ensures minimal power loss in switching applications.
The transistor supports input voltage ranges from −0.3 V to −10 V (VI(on) = −3.0 V typ.) and maintains < −0.5 μA leakage (IO(off)) at −50 V VCC, enabling reliable off-state isolation in 12 V automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −40 V - Ensures safe operation in 24 V automotive supply rails with margin against transients. |
| R1 / R2 | 1 kΩ / 10 kΩ - Enables direct TTL/CMOS logic-level drive without external bias network. |
| hFE | 56 min - Guarantees stable switching behavior across temperature with ≥2.5 mA base drive. |
| VCE(sat) | ≤ −0.3 V @ −50 mA - Limits conduction loss to <15 mW, critical for thermally constrained SOT23 layouts. |
| PD | 200 mW - Defines maximum continuous dissipation on standard FR4 with recommended pad layout. |

|---|---|---|---|
| DDTB123YC-7-F | R1 = 2.2 kΩ, R2 = 10 kΩ; hFE = 56 min; same VCEO/VCE(sat) | Higher input impedance → lower base current draw, but slower turn-on in high-speed PWM | Select when driving high-impedance logic sources or minimizing MCU I/O loading. |
| DDTB114EC-7-F | R1 = R2 = 10 kΩ; hFE = 56 min; same VCEO/VCE(sat) | Matched resistors simplify design for symmetric biasing; reduced gain margin at low IC | Prefer for bidirectional logic interface or where matched R1/R2 simplifies BOM management. |

FAQ
What is the maximum continuous collector current for DDTB113ZC-7-F?
The absolute maximum continuous collector current is −500 mA, validated under conditions specified in DS30385 Rev. 10–2. Derating applies above +25°C ambient: linear reduction to 0 mA at +150°C junction temperature, based on 625 °C/W thermal resistance and 200 mW power limit.
Is DDTB113ZC-7-F qualified for automotive use?
Yes - DDTB113ZC-7-F is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It meets stress test requirements including temperature cycling, highly accelerated life testing (HALT), and humidity testing per JESD22 standards, supporting PPAP documentation upon request.
How does the internal resistor network affect PCB layout?
The monolithic 1 kΩ/10 kΩ bias network eliminates two external resistors and associated traces, reducing layout area by ~2 mm² and removing solder joint reliability risks. No external base pull-up/down is required, simplifying routing near microcontroller GPIO pins.
What is the typical saturation voltage at full rated current?
VCE(sat) is typically −0.3 V at −50 mA collector current and −2.5 mA base drive, measured per DS30385 Rev. 10–2. This value remains stable across −40°C to +125°C operating range, ensuring predictable power loss in thermally demanding environments.
