Product details
Overview
DN0150BDJ-7 from Diodes Incorporated is a dual NPN surface-mount transistor in SOT-963 package, rated for 50 V VCEO, 100 mA IC, and 300 mW power dissipation, with hFE of 200–400 at 2 mA/6 V, optimized for compact signal switching in portable consumer electronics and LED driver bias networks.
For engineers reviewing the DN0150BDJ-7 datasheet, DN0150BDJ-7 pinout, DN0150BDJ-7 application, or DN0150BDJ-7 equivalent, key selection criteria include verified dual-NPN matching, ultra-small SOT-963 footprint, guaranteed hFE range, low VCE(SAT) (0.10–0.25 V), and RoHS-compliant matte tin terminations suitable for high-density automated assembly.
Technical Context
This device integrates two matched epitaxial planar NPN transistors on a single die within a 6-terminal SOT-963 package, enabling space-constrained dual-switch or current-mirror configurations without inter-device parameter drift. Its fT of 60 MHz supports audio-frequency amplification and digital logic-level translation up to ~10 MHz.
Thermal resistance RθJA is 417°C/W on FR-4 PCB with minimum pad layout, and operation is specified across –55°C to +150°C ambient, with moisture sensitivity level 1 per J-STD-020D-enabling reflow compatibility without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC | 100 mA - continuous collector current handling capacity under thermal limits |
| hFE | 200–400 - DC current gain at VCE = 6 V, IC = 2 mA, defining base drive efficiency |
| VCE(SAT) | 0.10–0.25 V - saturation voltage at IC = 100 mA, IB = 10 mA, critical for low-loss switching |
| fT | 60 MHz - transition frequency indicating usable bandwidth for small-signal amplification |
| PD | 300 mW - maximum power dissipation on standard FR-4 board, limiting thermal design margin |
| RθJA | 417°C/W - junction-to-ambient thermal resistance, dictating temperature rise per watt |
Pinout & Package
Package: SOT-963 - ultra-small 6-pin surface-mount plastic package (1.0 × 1.0 × 0.5 mm), UL 94V-0 rated, lead-free and "Green" compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter Q1 | Emitter terminal of first NPN transistor; referenced to ground in common-emitter switch |
| 2 | Base Q1 | Control input for Q1; requires ~0.7 V forward bias and sufficient IB to saturate Q1 |
| 3 | Collector Q1 | Output node for Q1; sinks current when Q1 is active; connects to load or next stage |
| 4 | Collector Q2 | Output node for second NPN transistor; electrically isolated from Q1 collector |
| 5 | Base Q2 | Independent control input for Q2; enables synchronous or differential switching |
| 6 | Emitter Q2 | Emitter terminal of second NPN transistor; may be tied to Q1 emitter or used separately |
Key Features
| Feature | Design Value |
|---|---|
| Dual matched NPN transistors | Integrated on single die for consistent hFE, VBE, and thermal tracking in current mirrors or push-pull pairs |
| SOT-963 ultra-compact footprint | 1.0 mm × 1.0 mm area saves >60% board space vs. two discrete SOT-23 devices |
| Matte tin annealed terminations | Guaranteed solderability per MIL-STD-202 Method 208, compatible with lead-free reflow profiles |
| Moisture Sensitivity Level 1 | No dry-pack or baking required prior to assembly-reduces manufacturing overhead |
Applications
| LED Bias Control | Portable Audio Amplifier Stage |
|---|---|
Use Scenario: Driving dual-color indicator LEDs in wearables with independent on/off control. IC Role / Device Role / Timing Role: Dual NPN switch providing low-VCE(SAT) current sinking for red/green LED anodes tied to VCC. Use Value: Enables precise brightness control via PWM at base pins while minimizing heat generation (<0.25 V drop at 20 mA). | Use Scenario: Pre-amplifier stage in mono headphone driver ICs requiring matched gain paths. IC Role / Device Role / Timing Role: Dual NPN configured as cascode pair to extend bandwidth and improve linearity. Use Value: 60 MHz fT and tight hFE matching (200–400) ensure stable small-signal gain up to 20 kHz with <0.5% distortion. |
| Low-Power Sensor Interface | USB-C Power Path Switching |
Use Scenario: Level-shifting and buffering analog sensor outputs (e.g., thermistor divider) into MCU ADC inputs. IC Role / Device Role / Timing Role: Emitter-follower buffer for impedance transformation and noise isolation. Use Value: Low input capacitance (Cob = 1.3 pF) preserves signal integrity above 100 kHz; VBE(ON) stability across –55°C to +150°C ensures calibration accuracy. | Use Scenario: Controlling 5 V USB-C VCONN or accessory detection lines in mobile accessories. IC Role / Device Role / Timing Role: Dual low-side switch enabling independent enable/disable of two auxiliary power rails. Use Value: 50 V VCEO rating provides 2× safety margin over 5 V rail; SOT-963 footprint allows placement adjacent to USB-C connector without routing congestion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DST847BDJ | Same SOT-963 package; hFE = 200–400; VCEO = 45 V; VCE(SAT) = 0.15–0.30 V | Lower VCEO reduces margin in 3.3 V–5 V systems with transient spikes | Select if legacy design already uses DST847BDJ and VCEO derating is acceptable |
| EMX16T2R | SOT-563 package; hFE = 120–270; VCEO = 50 V; RθJA = 450°C/W | Larger footprint (1.6 × 1.6 mm) and higher thermal resistance limit power density | Choose only if SOT-563 is standardized in production and dual-transistor matching tolerance is relaxed |
Compared with DST847BDJ and EMX16T2R, DN0150BDJ-7 offers the highest VCEO/IC ratio in the smallest footprint, with lowest RθJA among SOT-963 dual-NPNs-making it optimal for thermally constrained, high-reliability portable designs where board area is premium.

FAQ
Is DN0150BDJ-7 still in active production?
No-DN0150BDJ-7 was officially discontinued by Diodes Incorporated as of June 2021 (DS31484 Rev. 4). However, Aetrix Electronics maintains verified, traceable inventory sourced exclusively from authorized Diodes distribution channels, with full lot traceability and test reports available upon request.
What is the functional replacement recommended by Diodes?
Diodes recommends DST847BDJ as the direct functional replacement, sharing identical SOT-963 packaging, pinout, and hFE range. Key differences include a reduced 45 V VCEO rating and slightly higher VCE(SAT); system-level transient testing is advised before migration.
Can DN0150BDJ-7 be used in place of a single NPN transistor?
Yes-either transistor within the dual unit can be used independently by leaving the unused base open and connecting its emitter and collector as needed. The unmatched transistor remains electrically isolated, preserving performance of the active channel without cross-talk or parameter shift.
What is the maximum allowable PCB trace width for SOT-963 thermal relief?
Per Diodes' layout guidance in DS31484, the recommended copper pad for each terminal is 0.35 mm × 0.35 mm with 0.15 mm thermal spokes. Increasing trace width beyond 0.25 mm per side degrades RθJA predictability and risks solder joint voiding during reflow due to uneven heating.
