Product details
Overview
DDC123JH-7 from Diodes Incorporated is an NPN pre-biased dual small-signal transistor in SOT-563 package, featuring integrated 2.2 kΩ and 47 kΩ bias resistors. It delivers VCEO = 50 V, IO(max) = 100 mA, VCE(sat) ≤ 0.3 V at IC/IB = 5 mA / 0.25 mA, and operates across –55°C to +150°C. It is used in digital logic interface circuits for level translation and load switching in compact consumer and industrial control modules.
For engineers reviewing the DDC123JH-7 datasheet, DDC123JH-7 pinout, DDC123JH-7 application, or DDC123JH-7 equivalent, key selection criteria include input threshold voltage (VIN(on) = 0.5 V), output saturation voltage, built-in resistor ratio, thermal resistance (RθJA = 833°C/W), and RoHS/Green compliance status.
Technical Context
This dual NPN transistor integrates two identical pre-biased elements sharing common emitter terminals, each with R1 = 2.2 kΩ and R2 = 47 kΩ. It functions as a current-controlled switch optimized for direct TTL/CMOS logic drive without external base resistors.
The device supports rail-to-rail input operation from –5 V to +12 V and maintains low VCE(sat) under IC ≤ 5 mA, enabling efficient signal inversion and open-collector output emulation in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V industrial logic interfaces. |
| IO(max) | 100 mA - Continuous output current per channel; sufficient for driving LEDs, relays, or small MOSFET gates. |
| VCE(sat) | ≤ 0.3 V at IC/IB = 5 mA / 0.25 mA - Ensures minimal power loss and heat generation during saturation. |
| VIN(on) | 0.5 V @ IO = 5 mA - Low turn-on threshold compatible with 1.8 V and 3.3 V logic families. |
| R1/R2 | 2.2 kΩ / 47 kΩ - Fixed internal bias network eliminates need for external resistors, reducing BOM count and layout area. |
| PD | 150 mW - Power dissipation limit at TA = 25°C; derates linearly above 25°C per 833°C/W thermal resistance. |
| Tj/TSTG | –55°C to +150°C - Wide operating and storage range supports automotive under-hood and industrial ambient conditions. |
Pinout & Package
Package: SOT-563 - 6-pin ultra-small surface-mount package (2.2 mm × 1.35 mm × 0.6 mm), UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base of Q1 | Connected internally to R1 (2.2 kΩ) and R2 (47 kΩ); accepts logic-level input for Q1. |
| 2 | Emitter of Q1 | Common emitter node shared with Q2; tied to GND or reference potential in standard switch configuration. |
| 3 | Collector of Q1 | Active output node for Q1; sinks up to 100 mA when saturated. |
| 4 | Collector of Q2 | Active output node for Q2; electrically independent but thermally coupled to Q1. |
| 5 | Emitter of Q2 | Shared emitter terminal with Pin 2; enables dual-channel operation with single reference connection. |
| 6 | Base of Q2 | Connected internally to R1 and R2; accepts independent logic-level input for Q2. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar pre-biased dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DDC114EH-7 | R1/R2 = 10 kΩ / 10 kΩ; higher input current (0.88 mA @ 5 V); VIN(on) = 0.5 V | Better suited for higher-speed switching where lower base impedance improves rise/fall times. | Select when driving capacitive loads >50 pF or requiring faster transition response. |
| DDC143EH-7 | R1/R2 = 4.7 kΩ / 4.7 kΩ; higher IO = 100 mA; VIN(on) = 0.3 V; wider input range (–10 V to +30 V) | Optimized for wide-supply industrial sensors and legacy 5 V logic with tighter noise margins. | Prefer for designs needing enhanced noise immunity or compatibility with older 5 V TTL systems. |
Compared with DDC114EH-7 and DDC143EH-7, DDC123JH-7 offers the lowest input current (1.8 mA @ 5 V) and highest R1/R2 ratio, making it ideal for ultra-low-power logic interfacing where base current minimization is critical.

FAQ
What is the maximum safe operating voltage for DDC123JH-7?
The absolute maximum collector-emitter voltage (VCEO) is 50 V, and the maximum input voltage range is –5 V to +12 V. Exceeding these limits risks permanent damage. Operation at 24 V DC loads is fully supported with appropriate current limiting on the collector side.
Can DDC123JH-7 replace discrete transistor + resistor combinations?
Yes - each channel replaces one NPN transistor plus two bias resistors (Rbase, Rpull-down). The internal 2.2 kΩ/47 kΩ network provides precise biasing for saturation at IC ≤ 5 mA, eliminating layout variability and solder joint reliability concerns associated with discrete passives.
Is thermal performance validated on standard FR4 PCB?
Yes - the specified RθJA of 833°C/W is measured on a 1-inch² FR4 board with the recommended pad layout per AP02001. Derating begins at 25°C ambient; at 70°C ambient, maximum power dissipation drops to ~85 mW per channel.
Does DDC123JH-7 support bidirectional signal routing?
No - it is a unidirectional NPN switch with fixed emitter-common topology. The base terminals accept only positive input signals; the collectors sink current only. It cannot function as a bidirectional bus switch or analog multiplexer.
