Engineered for general-purpose voltage regulation and medium-current applications, this 2-pin semiconductor provides a nominal Zener voltage of 10V with a tight tolerance range spanning from 9.4V to 10.6V at a test current of 5mA. Featuring a maximum power dissipation rating of 500mW when mounted on a ceramic PCB, the device delivers reliable thermal and electrical performance across a wide operating and storage temperature range of -65°C to +150°C. Key electrical parameters include a maximum dynamic Zener impedance of 20 $\Omega$ at the test current, alongside a low reverse leakage current of 0.2 µA at a reverse voltage of 7V. The component exhibits a forward voltage drop of 0.9V maximum at a forward current of 10 mA. Its standardized SOD-123 case style and solderable terminals per MIL-STD-202 Method 208 make it ideally suited for automated pick-and-place assembly processes in space-constrained printed circuit board layouts. This Zener diode is well-suited for integration into power conversion circuitry, analog signal conditioning modules, and reference voltage clamping networks within industrial and consumer electronics. Its stable breakdown characteristics and thermal coefficient profile ensure dependable voltage stabilization and transient protection in circuits requiring tight regulation tolerances. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (04-Feb-2026) | | No. Of Pins | 2Pins | | Product Range | BZT52 | | Qualification | - | | Diode Mounting | Surface Mount | | Diode Case Style | SOD-123 | | Power Dissipation | 500mW | | Zener Voltage Nom | 10V | | Operating Temperature Max | 150°C | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:1902426RL/) ## **BZT52C2V4 - BZT52C51** ## **SURFACE MOUNT ZENER DIODE** ## **Features** Planar Die Construction 500mW Power Dissipation on Ceramic PCB General Purpose, Medium Current Ideally Suited for Automated Assembly Processes |Planar Die Construction
