Product details
Overview
DVR2V5W-7 from Diodes Incorporated is a discontinued SOT363-packaged complex array integrating one NPN transistor and one 5.1 V Zener diode, designed for series-pass voltage regulator circuits with 18 V VCEO, 45 V VCBO, 5.1 V nominal Zener voltage at 50 µA, and 200 mW total power dissipation. It enables compact, low-quiescent-current (0.5 mA typical) 5 V regulation from 6 V input in space-constrained industrial power supplies.
For engineers reviewing the DVR2V5W-7 datasheet, DVR2V5W-7 pinout, DVR2V5W-7 application, or DVR2V5W-7 equivalent, this page delivers verified technical context, validated pin functions, real-world regulator design parameters, and confirmed alternative options for legacy system maintenance and BOM continuity planning.
Technical Context
This device integrates a matched NPN transistor and Zener diode on a single die to form a discrete-series regulator building block. Its 18 V VCEO and 5.1 V Zener enable stable 5 V output regulation with ≥1 V headroom, while hFE of 150–800 supports current gain control across 100 mA load range.
The SOT363 package provides six terminals with two NC pins, requiring external base biasing via resistor network. Thermal resistance of 625 °C/W (FR-4, 1-inch² 2 oz Cu) limits continuous operation to ≤125 °C ambient at full 200 mW dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 5.1 V nominal at 50 µA; defines regulated output voltage in series-pass configuration |
| VCEO | 18 V maximum; sets minimum input-to-output differential required for transistor saturation |
| hFE | 150–800 at IC = 100 mA, VCE = 1 V; determines base drive resistor sizing for load current control |
| Pd | 200 mW maximum; constrains total power handling on standard FR-4 PCB without forced cooling |
| VCE(SAT) | ≤0.5 V at IC = 300 mA, IB = 30 mA; limits dropout voltage and conduction loss under full load |
| RθJA | 625 °C/W; requires derating above 25 °C ambient-e.g., 100 mW max at 100 °C ambient |
Pinout & Package
SOT363 surface-mount package: 2.15 mm × 2.10 mm × 0.95 mm body, 0.65 mm pitch, matte tin-plated Alloy 42 leadframe, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | NC | No internal connection; must remain unconnected per datasheet top view |
| E1 | Emitter (NPN) | Output node in series-pass regulator; connects to load and feedback path |
| K1 | Cathode (Zener) | Connected to base of NPN transistor in standard regulator topology |
| C1 | Collector (NPN) | Input node; ties to unregulated supply rail (e.g., 6 V) |
| B1 | Base (NPN) | Control node; biased via external resistor to Zener cathode (K1) |
| NC | NC | No internal connection; second unused terminal per SOT363 pinout |
Key Features
| Feature | Design Value |
|---|---|
| Integrated NPN + Zener pair | Enables single-component series-pass regulator with matched thermal tracking between control elements |
| 18 V VCEO rating | Supports input voltages up to 6 V for 5 V output with ≥1 V headroom margin |
| 0.5 V VCE(SAT) max | Minimizes dropout and power loss at 100 mA load (≤50 mW conduction loss) |
| 200 mW Pd rating | Permits use in low-power industrial modules without heatsinking on standard PCB layout |
Applications
| Industrial Power Supply | Legacy Microcontroller Bias Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar series-pass voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTR2005F | Integrated LDO with 5 V fixed output, 150 mA rated, 250 mW Pd, no external bias needed | Eliminates base resistor but lacks adjustable output; requires PCB layout change | Preferred for new designs where footprint reduction and simplified biasing outweigh need for adjustability |
| MMBT3904 + BZX55-C5V1 | Discrete NPN + Zener pair in SOT23/SOD-123; identical electrical specs but separate packages | Requires two placements and routing; increases assembly cost and board area by ~3× | Used only when DVR2V5W-7 is unavailable and legacy layout cannot accommodate SOT363 footprint |
Compared with ZXTR2005F and MMBT3904+BZX55-C5V1, DVR2V5W-7 offers optimal balance of integration density, thermal coupling, and legacy compatibility-making it irreplaceable for maintaining existing SOT363-based regulator designs without performance compromise.

FAQ
Is DVR2V5W-7 still in production?
No-DVR2V5W-7 is officially obsolete and discontinued per Diodes Incorporated's DS30578 Rev. 8 (October 2021). Aetrix Electronics maintains limited legacy stock and supports last-time buy programs with full traceability and extended warranty for active production lines dependent on this component.
What is the correct pin 1 orientation for DVR2V5W-7?
Pin 1 is the A1 terminal (NC), located at the top-left corner of the SOT363 package when the marking "VR04" is read left-to-right with the notch or dot at the top-left. The top-view diagram in DS30578 confirms A1–E1–K1–C1–B1–NC sequence clockwise from that corner.
Can DVR2V5W-7 regulate 3.3 V output?
No-it contains a fixed 5.1 V Zener element and is not adjustable. To achieve 3.3 V regulation, an external Zener or reference must replace the internal 5.1 V Zener, which is not feasible due to monolithic die construction. Use ZXTR2003F or AP2112K-3.3 instead.
What is the maximum safe load current for DVR2V5W-7 at 85°C ambient?
At 85°C ambient, derated power dissipation is 120 mW (per Fig. 1). With 0.5 V VCE(SAT) and 1 V dropout, max load current is ~100 mA-matching the datasheet's 100 mA test condition and ensuring junction temperature stays below 150°C.
