Nexperia USA Inc. BZV55-B15,115

Overview

BZV55-B15,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, designed for precision voltage reference and regulation in low-current biasing circuits. It delivers a nominal 15 V Zener voltage with ±2 % tolerance (B-series), 75 Ω typical differential resistance at 5 mA, and a temperature coefficient of +9.2 mV/K - enabling stable operation in ambient-temperature-sensitive analog signal chains and power-supply feedback paths.

For engineers reviewing the BZV55-B15,115 datasheet, BZV55-B15,115 pinout, BZV55-B15,115 application, or BZV55-B15,115 equivalent, this part supports design validation of voltage references in linear regulators, overvoltage clamping in sensor interfaces, and bias stabilization in op-amp circuits - with attention to thermal resistance (R_th(j-a) = 380 K/W), non-repetitive surge capability (40 W, 100 µs), and reverse leakage (<50 nA at 10.5 V).

Technical Context

This Zener diode operates in reverse breakdown mode with tightly controlled V_Z = 14.7–15.3 V at I_Z = 5 mA, exhibiting low dynamic impedance (50–200 Ω) and positive temperature coefficient (+9.2 mV/K typ.) - critical for compensating drift in voltage references across industrial temperature ranges. Its SOD80C package enables compact PCB layout while maintaining hermetic sealing for long-term stability under humidity exposure.

The device complies with IEC 60134 absolute maximum ratings: P_tot = 500 mW (T_amb ≤ 50 °C), I_F = 250 mA forward, and non-repetitive peak reverse power dissipation of 40 W (100 µs square wave). Reverse leakage remains below 50 nA at 0.7×V_Z(nom), supporting low-power standby circuit integrity.

FAQ

What is the maximum continuous power dissipation for BZV55-B15,115 at 70 °C ambient?

At T_amb = 70 °C, derating applies: P_tot drops linearly from 500 mW at 50 °C to 0 mW at 150 °C. Using R_th(j-a) = 380 K/W, maximum continuous power is 300 mW - calculated as 500 mW × (1 − (70−50)/100). Exceeding this risks junction overheating and parametric shift.

Can BZV55-B15,115 be used in series for higher-voltage references?

Yes - two BZV55-B15,115 diodes in series yield ~30 V with ±2.8 % combined tolerance (root-sum-square), provided equal current sharing via ballast resistors. Differential resistance adds linearly (≈100 Ω), preserving regulation stiffness. Avoid parallel connection due to mismatched V_Z causing current hogging.

How does the +9.2 mV/K temperature coefficient impact long-term stability?

The positive coefficient means V_Z increases ~0.138 V over a 15 °C rise (e.g., 25 °C to 40 °C). In closed-loop systems like shunt regulators, this drift is partially compensated by opposing op-amp or transistor thermal effects - verified in Nexperia's application note AN10772 for reference design validation.

Is the SOD80C package compatible with standard reflow profiles?

Yes - the glass SOD80C package is rated for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C for ≤30 seconds. Footprint dimensions (3.3–3.7 mm × 1.45–1.60 mm) match IPC-7351B SOIC-2 land patterns, and solder paste volume must be reduced by 20 % versus plastic SMD packages to prevent tombstoning.
