1SMA200Z R3G

Single Zener Diodes Overview

The 1SMA200Z R3G is a single-die surface mount Zener diode manufactured by Taiwan Semiconductor Corporation. It operates within the DO-214AC (SMA) package and provides a nominal Zener voltage of 200 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W at 25°C ambient temperature, increasing to 1.25 W at 60°C. Key electrical parameters include a test current of 1.2 mA, a maximum Zener impedance of 1500 Ω, and a leakage current of 1 µA measured at 152 V. The component functions reliably across a junction temperature range of -55°C to +175°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'R3G' against the manufacturer's current datasheet to confirm packaging details and compliance status. Confirm that the part number revision matches the intended design requirements, as manufacturers may update identifiers without altering core functionality. Cross-reference the RoHS and REACH declarations with the latest environmental documentation provided by Taiwan Semiconductor before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 200 V reference or clamp is required in a compact SMA footprint. Ensure the circuit design accommodates the specified 1500 Ω dynamic impedance and 1.2 mA test current conditions. Verify that the thermal management strategy supports the 1 W power dissipation rating under expected operating temperatures. Consider the low leakage characteristics for high-impedance signal paths requiring minimal current draw.
