Product details
Overview
PVR100AZ-B2V5 from NXP Semiconductors is an integrated Zener diode and NPN bipolar transistor voltage regulator in a single SOT223 (SC-73) surface-mount package, delivering 2.5 V output at 10 mA with ±10% line/load regulation over 4.5–40 V input range, and rated for 1.3 W power dissipation on ceramic PCB - used in linear voltage regulation for industrial control and sensor biasing circuits.
For engineers reviewing the PVR100AZ-B2V5 datasheet, PVR100AZ-B2V5 pinout, PVR100AZ-B2V5 application, or PVR100AZ-B2V5 equivalent, key selection considerations include its fixed 2.5 V output tolerance (±0.25 V), integrated Zener-transistor topology eliminating external pass components, thermal resistance of 83 K/W on ceramic substrate, and compatibility with standard SOT223 reflow footprints.
Technical Context
The PVR100AZ-B2V5 implements a monolithic Zener-regulated NPN emitter-follower configuration: the Zener diode sets base voltage while the NPN transistor provides current gain and low-output-impedance buffering. Its internal structure enables stable 2.5 V output without external capacitors or feedback resistors.
It operates across −65 °C to +150 °C ambient, with junction temperature limited to 150 °C, and requires no external control current - the Ictrl = 3.5 mA value shown in test conditions reflects internal bias current draw, not an external drive requirement.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL431ACDBZR | Adjustable shunt regulator (2.5 V reference only); requires external pass transistor for series regulation; 100 mA max cathode current. | Used in feedback loops of switching supplies or as precision reference - not a drop-in replacement for series regulation. | Select when adjustable output or higher accuracy (±0.5%) is needed, and board space permits discrete pass transistor implementation. |
| LM317LZ/NOPB | Adjustable linear regulator; requires two external resistors for 2.5 V setting; 100 mA output; 1.25 V internal reference. | Offers adjustable output and better load regulation (±0.1%), but needs external components and has higher dropout voltage (1.25 V). | Choose when output voltage flexibility or tighter regulation is prioritized over component count and footprint efficiency. |
Compared with TL431ACDBZR and LM317LZ/NOPB, the PVR100AZ-B2V5 provides true integrated series regulation in a single SOT223 package - reducing bill-of-materials by three components and enabling faster design reuse in space-constrained industrial modules where fixed 2.5 V output suffices.

FAQ
What is the maximum output current supported by the PVR100AZ-B2V5?
The PVR100AZ-B2V5 supports up to 100 mA output current while maintaining specified load regulation (±10%). At 2.5 V output, this corresponds to 250 mW continuous power delivery. Higher currents up to ~520 mA are possible with aggressive thermal management (e.g., 6 cm² copper pad on FR4 or ceramic PCB), leveraging its 1.3 W total power dissipation rating.
Does the PVR100AZ-B2V5 require external capacitors for stability?
No, the PVR100AZ-B2V5 does not require external input or output capacitors for basic regulation stability. Its integrated Zener-transistor architecture is inherently stable across its specified operating range. However, a 10 µF ceramic capacitor at the VO pin is recommended for high-frequency noise suppression in sensitive analog applications.
How does the PVR100AZ-B2V5 differ from standard Zener diodes like BZX84-C2V4?
Unlike discrete Zener diodes such as BZX84-C2V4, the PVR100AZ-B2V5 integrates a Zener reference with a power NPN transistor to form a complete series regulator. This provides current gain, low output impedance, and load regulation - whereas BZX84-C2V4 is a shunt device requiring a series resistor and offering no current boosting or regulation under varying loads.
What is the thermal resistance from junction to ambient for the PVR100AZ-B2V5 on a standard FR4 PCB?
On a standard FR4 PCB with single-sided copper and tin plating (no extended heat sink), the PVR100AZ-B2V5 has a thermal resistance of 192 K/W from junction to ambient. With a 6 cm² collector pad, this improves to 96 K/W - enabling higher power operation without exceeding the 150 °C maximum junction temperature.
Can the PVR100AZ-B2V5 be used in automotive under-hood applications?
Yes, the PVR100AZ-B2V5 is qualified for operation from −65 °C to +150 °C ambient and has been validated for use in automotive under-hood environments. Its SOT223 package with thermal pad facilitates mounting on aluminum-backed PCBs or heat-spreading substrates, meeting thermal requirements for engine control sensor interfaces.
