NXP Semiconductors Z0107NA,116

Overview

Z0107NA,116 from WeEn Semiconductors is a planar passivated 4-quadrant triac in TO-92 (SOT54) package, rated for 800 V repetitive peak off-state voltage, 1 A RMS on-state current, and 8 A non-repetitive peak on-state current. It features very sensitive gate triggering (≤7 mA max across all quadrants), enabling direct interface with logic-level ICs and low-power gate drivers in AC switching applications.

For engineers reviewing the Z0107NA,116 datasheet, Z0107NA,116 pinout, Z0107NA,116 application, or Z0107NA,116 equivalent, key selection criteria include gate sensitivity in QIII (T2−/G+), dV/dt immunity (20 V/µs), thermal resistance (60 K/W junction-to-lead), and compatibility with zero-crossing or phase-angle control topologies in low-power AC loads.

Technical Context

The Z0107NA,116 operates as a bidirectional thyristor switch with symmetrical triggering capability in all four quadrants (QI–QIV), supporting both positive- and negative-polarity gate drive relative to MT2. Its planar passivation ensures stable blocking performance up to 800 V under transient overvoltage conditions.

It delivers latching current ≤10 mA and holding current ≤10 mA at 25 °C, with on-state voltage of 1.3–1.6 V at 1 A, and critical dV/dt rating of 20 V/µs at 110 °C - enabling reliable commutation in inductive fan and motor control circuits without snubber networks in many cases.

FAQ

What is the maximum gate trigger current specification for Z0107NA,116 in quadrant III?

The maximum gate trigger current for Z0107NA,116 in quadrant III (T2−/G+) is 7 mA at 25 °C, as confirmed in Table 6 of the official datasheet. This low I_GT value enables direct connection to 3.3 V or 5 V microcontroller GPIOs without external amplification. The Z0107NA,116 maintains this sensitivity across its operating temperature range, with normalized curves showing less than 2× increase up to 125 °C junction temperature.

Does Z0107NA,116 support triggering in all four quadrants?

Yes, Z0107NA,116 is explicitly specified as a 4-quadrant triac, with verified gate trigger current values provided for all four combinations: T2+/G+, T2+/G−, T2−/G−, and T2−/G+. Each quadrant has a maximum I_GT ≤7 mA, ensuring consistent logic-level drivability regardless of AC phase polarity. This capability eliminates the need for external gate protection diodes in most AC-coupled control circuits.

What is the thermal resistance from junction to lead for Z0107NA,116?

The thermal resistance from junction to lead (R_th(j-lead)) for Z0107NA,116 is 60 K/W, as stated in Table 5 of the datasheet under "Thermal characteristics." This value applies under full-cycle conduction conditions and enables accurate junction temperature estimation when lead temperature is measured. For example, at 1 A RMS conduction, the junction-to-lead temperature rise is ≤60 °C - a key parameter for thermal design in sealed or convection-limited enclosures.

Can Z0107NA,116 be used in 230 V AC mains applications?

Yes, Z0107NA,116 is rated for 800 V repetitive peak off-state voltage (V_DRM), which provides a 2.5× safety margin over 230 V RMS mains (325 V peak). Its dV/dt rating of 20 V/µs and planar passivation further ensure reliable blocking under real-world line transients. The Z0107NA,116 is widely deployed in 230 V AC fan controllers and appliance timers, with validated performance up to 125 °C junction temperature.

What is the on-state voltage of Z0107NA,116 at 1 A current?

The on-state voltage (V_T) of Z0107NA,116 is specified as 1.3 V (typical) to 1.6 V (maximum) at 1 A and 25 °C junction temperature, per Table 6. This low conduction drop results in ≤1.6 W power dissipation at full rated current, supporting operation without forced cooling in standard TO-92 mounting configurations. The Z0107NA,116 maintains stable V_T across temperature, with typical values rising only modestly at elevated junction temperatures.
