onsemi NZD6V2MUT5G

Overview

NZD6V2MUT5G from onsemi is a 200 mW surface-mount Zener diode with nominal reverse breakdown voltage of 6.2 V (5.89–6.51 V), 60 Ω maximum Zener impedance at 5 mA test current, and 110 pF capacitance at 0 V/1 MHz; it provides precision voltage regulation in space-constrained mobile power rails and ESD-protected I/O clamping circuits.

For engineers reviewing the NZD6V2MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include its 6.2 V regulation tolerance, 200 mW power rating on FR-5 board, MSL 1 reflow compatibility, Class 3 HBM ESD rating (>8 kV), and X3DFN2 0.62 mm × 0.32 mm × 0.24 mm package.

Technical Context

This device operates as a two-terminal voltage reference and transient clamp, leveraging silicon PN-junction Zener breakdown at 6.2 V under controlled reverse bias. Its low 0.30 mm body height and 0.60 mm × 0.30 mm footprint enable integration into ultra-thin portable PCBs.

Thermal resistance of 400 °C/W (junction-to-ambient, FR-5 board) and derating curve support stable operation up to +150 °C junction temperature. The −55 °C to +150 °C storage/junction range and 260 °C max solder temperature align with industrial and automotive-grade reflow profiles.

FAQ

What is the Zener voltage tolerance of NZD6V2MUT5G?

The NZD6V2MUT5G has a specified Zener voltage range of 5.89 V to 6.51 V at 5 mA test current (I_ZT), representing a ±5% tolerance around the nominal 6.2 V rating. This tolerance is guaranteed across production lots and measured at 25 °C ambient per the onsemi datasheet. The NZD6V2MUT5G maintains this specification without requiring binning or post-manufacturing calibration.

Does NZD6V2MUT5G support lead-free reflow soldering?

Yes, NZD6V2MUT5G is qualified for lead-free reflow soldering with a maximum peak temperature of 260 °C for 10 seconds and meets MSL 1 requirements. Its X3DFN2 package is Pb-free, halogen-free, and RoHS-compliant. The NZD6V2MUT5G can be processed using standard J-STD-020-compliant reflow profiles without thermal damage or reliability degradation.

What is the maximum steady-state power dissipation for NZD6V2MUT5G?

The NZD6V2MUT5G has a maximum steady-state power dissipation of 200 mW at 25 °C ambient temperature on an FR-5 board, as defined in the Absolute Maximum Ratings table. Derating is required above 25 °C per the published curve (Figure 1), reaching zero dissipation at approximately 125 °C ambient. The NZD6V2MUT5G's thermal resistance is 400 °C/W junction-to-ambient under these test conditions.

How does the capacitance of NZD6V2MUT5G affect high-speed signal lines?

The NZD6V2MUT5G exhibits 110 pF capacitance at 0 V reverse bias and 1 MHz frequency, which minimally loads USB 2.0 (480 Mbps) or UART signals when used for I/O clamping. This value is low enough to avoid measurable rise/fall time degradation in most portable designs. The NZD6V2MUT5G's capacitance remains stable across bias, making it predictable in signal-path protection roles.

Is NZD6V2MUT5G suitable for automotive applications?

Yes, NZD6V2MUT5G is suitable for automotive applications due to its −55 °C to +150 °C junction/storage temperature range, MSL 1 reflow rating, and Class 3 (>8 kV) HBM ESD performance. It is commonly deployed in infotainment I/O clamping and sensor biasing within AEC-Q200-adjacent systems. The NZD6V2MUT5G is not AEC-Q200-qualified itself but meets key parametric and mechanical requirements for under-hood and cabin modules.
