Product details

Overview

PZU2.7B1,115 from NXP Semiconductors is a precision Zener diode in SOD323F (SC-90) surface-mount package, designed for voltage regulation and reference functions at 2.7 V nominal Zener voltage with ±2 % tolerance (B1 grade), 310 mW total power dissipation at 25 °C ambient, and 100 Ω maximum differential resistance at I_Z = 5 mA. It serves in low-power analog supply rails and signal-level clamping circuits.

For engineers reviewing the PZU2.7B1,115 datasheet, PZU2.7B1,115 pinout, PZU2.7B1,115 application, or PZU2.7B1,115 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (R_th(j-a) = 400 K/W), reverse current at 1 V (≤20 μA), forward voltage at 100 mA (≤1.1 V), and SOD323F footprint compatibility with automated assembly.

Technical Context

This device operates as a single-junction silicon Zener diode optimized for stable reverse-biased breakdown at low currents (IZ = 0.5 mA to 5 mA). Its temperature coefficient is −2.0 mV/K at I_Z = 5 mA, indicating predictable negative drift over temperature.

The SOD323F package enables high-density PCB layouts with minimal thermal mass; junction-to-ambient thermal resistance is 400 K/W in free air and improves to 230 K/W with standard FR4 mounting, supporting reliable operation up to 150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener voltage V_Z	2.5 V to 2.75 V at I_Z = 5 mA - defines tight regulation window for 2.7 V reference designs
Tolerance grade	B1 - ±2 % initial accuracy, enabling higher-precision feedback loops than ±5 % B-grade variants
Total power dissipation	310 mW at T_amb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB
Differential resistance r_dif	≤100 Ω at I_Z = 5 mA - ensures low dynamic impedance for stable regulation under load transients
Reverse current I_R	≤20 μA at V_R = 1 V - guarantees low leakage in standby or battery-powered circuits
Forward voltage V_F	≤1.1 V at I_F = 100 mA - supports use as low-drop rectifier or clamp in bidirectional protection schemes
Junction temperature	150 °C max - allows operation in industrial ambient environments without derating below 85 °C

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX384-B2V7	Same 2.7 V ±2 % rating but SOD323 package (not SOD323F); 400 mW P_tot; R_th(j-a) = 350 K/W	Higher power handling but larger footprint; less suitable for ultra-dense layouts	Select when thermal margin >310 mW is required and board space permits 0.2 mm larger body
MMSZ4678T1G	2.7 V ±5 % (B grade); SOD123 package; 500 mW P_tot; r_dif = 120 Ω	Looser tolerance and higher dynamic impedance; better for non-critical biasing	Choose for cost-sensitive applications where ±5 % accuracy suffices and 1.8 mm × 1.4 mm footprint is acceptable

Compared with BZX384-B2V7 and MMSZ4678T1G, PZU2.7B1,115 delivers superior accuracy and smallest footprint among 2.7 V Zeners, making it optimal for space-constrained, precision analog designs-though its 310 mW limit requires careful thermal layout planning.

FAQ

What is the Zener voltage tolerance of PZU2.7B1,115?

PZU2.7B1,115 has a B1 tolerance grade, meaning its nominal 2.7 V Zener voltage is guaranteed between 2.5 V and 2.75 V at I_Z = 5 mA. This ±2 % specification is tighter than the ±5 % offered by B-grade variants in the same PZUxB family, supporting higher-accuracy reference designs without calibration.

Does PZU2.7B1,115 support reflow soldering?

Yes, PZU2.7B1,115 is qualified for reflow soldering only-no wave or hand-soldering is recommended. Its SOD323F package meets JEDEC J-STD-020 moisture sensitivity level 1, and the datasheet specifies a peak reflow temperature of 260 °C for 10 seconds. The recommended footprint matches Figure 6 in the NXP PZUXB_SER_2 datasheet.

What is the maximum reverse current for PZU2.7B1,115 at 1 V?

At V_R = 1 V and T_j = 25 °C, the reverse current I_R for PZU2.7B1,115 is specified as ≤20 μA. This low leakage supports energy-efficient operation in always-on circuits such as real-time clock biasing or sensor wake-up detection, where sub-microamp drain is critical.

How does the temperature coefficient of PZU2.7B1,115 affect circuit stability?

PZU2.7B1,115 has a temperature coefficient of −2.0 mV/K at I_Z = 5 mA, meaning its Zener voltage decreases by approximately 2 mV per Kelvin rise in junction temperature. This predictable negative drift allows designers to compensate system-level errors in precision references, especially when paired with positive-tempco components like resistors or op-amps.

Can PZU2.7B1,115 be used in forward conduction mode?

Yes, PZU2.7B1,115 functions as a standard silicon diode in forward bias, with V_F ≤ 0.9 V at I_F = 10 mA and ≤1.1 V at I_F = 100 mA. This dual-mode capability enables use in bidirectional protection circuits-for example, clamping both positive and negative transients on data lines-without adding discrete rectifiers.
