Product details
Overview
PVR100AZ-B12V from NXP Semiconductors is an integrated voltage regulator combining a Zener diode and NPN bipolar transistor in a single SOT223 (SC-73) surface-mount package. It delivers a nominal 12 V output at 10 mA load, supports input voltages up to 40 V, exhibits ±7% line and load regulation, and provides 1.3 W power dissipation capability on ceramic PCB mounting - used for compact linear voltage regulation in industrial control and sensor signal conditioning circuits.
For engineers reviewing the PVR100AZ-B12V datasheet, PVR100AZ-B12V pinout, PVR100AZ-B12V application, or PVR100AZ-B12V equivalent, key selection considerations include its fixed 12 V output tolerance (11.4–13.2 V), thermal resistance of 83 K/W on ceramic substrate, Zener working voltage of 12.7–13.3 V at 5 mA, collector-emitter voltage rating of 45 V, and compatibility with standard SOT223 reflow footprints.
Technical Context
The PVR100AZ-B12V implements a two-stage regulation architecture: a precision Zener diode (VZ = 12.7–13.3 V at IZ = 5 mA) biases the base of an integrated NPN transistor (VCEO = 45 V, hFE = 160–400), enabling stable emitter-follower output. Its control current (Ictrl = 5 mA) sets bias point and directly impacts output accuracy and temperature drift.
Thermal performance is defined across three mounting conditions: FR4 standard footprint (Rth(j-a) = 192 K/W), FR4 with 6 cm² collector pad (Rth(j-a) = 96 K/W), and ceramic Al₂O₃ substrate (Rth(j-a) = 83 K/W), with maximum junction temperature rated at 150 °C and ambient operating range from −65 °C to +150 °C.
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 (2.5–36 V); requires external resistors; lower quiescent current (4 mA typ) | Used in feedback loops of switching supplies or precision references; not a drop-in replacement due to topology and pinout mismatch | Select when adjustable output or higher accuracy (<0.5%) is required; redesign needed for feedback network and layout |

FAQ
What is the maximum input voltage the PVR100AZ-B12V can handle?
The PVR100AZ-B12V supports a maximum input voltage of 40 V under specified line regulation test conditions (14 V ≤ VI ≤ 40 V). This limit is derived from its NPN transistor's VCEO rating of 45 V and ensures safe operation with sufficient headroom. Exceeding 40 V may compromise regulation accuracy or reliability, especially at elevated temperatures. Always verify worst-case VI in your design before selecting PVR100AZ-B12V.
Does the PVR100AZ-B12V require external components to function?
Yes, the PVR100AZ-B12V requires an external resistor connected to pin 1 (REXT) to set the Zener bias current (Ictrl = 5 mA). No other passive components are needed for basic operation. The resistor value is calculated based on input voltage and desired bias current - for example, with VI = 14 V, a ~1.8 kΩ resistor achieves ~5 mA. Output capacitance is optional but recommended for transient stability.
What is the output voltage tolerance of the PVR100AZ-B12V at 10 mA load?
The PVR100AZ-B12V guarantees an output voltage of 11.4 V (min) to 13.2 V (max) at IO = 10 mA and VI = 14 V, yielding a total tolerance of ±7% around the nominal 12 V. This specification includes contributions from line regulation (±7%), load regulation (±7%), and initial calibration error - all verified per NXP's Product Data Sheet Rev. 01.
Can the PVR100AZ-B12V be used in automotive under-hood applications?
Yes, the PVR100AZ-B12V is qualified for operation from −65 °C to +150 °C ambient temperature and features a 45 V VCEO rating, making it suitable for under-hood automotive environments. Its SOT223 package supports robust thermal management on ceramic or enhanced-copper PCBs. However, it is not AEC-Q100 qualified; system-level validation is required for safety-critical automotive functions.
How does thermal performance differ between FR4 and ceramic PCB mounting for the PVR100AZ-B12V?
On standard FR4 PCB, the PVR100AZ-B12V has Rth(j-a) = 192 K/W; with a 6 cm² collector pad, it improves to 96 K/W; on ceramic Al₂O₃ substrate, it reaches 83 K/W. This means at 1.3 W dissipation, junction temperature rise is ~250 °C on FR4 (exceeding 150 °C limit), ~125 °C with enhanced FR4, and ~108 °C on ceramic - confirming ceramic mounting is required for full-rated power operation.
