Product details
Overview
BZV55-B75,115 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 circuits. It delivers a nominal 75 V Zener voltage with ±2 % tolerance, 170 Ω typical differential resistance at IZ = 2 mA, and a temperature coefficient of +95 mV/K - enabling stable operation in power supply feedback paths, overvoltage protection clamps, and analog reference circuits.
For engineers reviewing the BZV55-B75,115 datasheet, BZV55-B75,115 pinout, BZV55-B75,115 application, or BZV55-B75,115 equivalent, key selection criteria include its 75 V nominal Zener voltage, ±2 % tolerance, 500 mW total power dissipation, 40 W non-repetitive peak reverse power rating, and SOD80C package thermal performance (Rth(j-a) = 380 K/W).
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its terminals under controlled current conditions. Its design targets low-noise, low-drift voltage regulation in DC-DC converter feedback networks and analog sensor biasing circuits where tight voltage accuracy and predictable temperature behavior are required.
The device exhibits a positive temperature coefficient (+95 mV/K) at IZ = 2 mA, indicating increasing Zener voltage with junction temperature - a critical factor when designing temperature-compensated references. Its 170 Ω typical differential resistance ensures minimal voltage variation over small changes in Zener current, supporting high-accuracy regulation in low-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 73.5 V to 76.5 V at IZ = 2 mA - defines precise regulation point for feedback or clamping |
| Differential Resistance (rdif) | 170 Ω typical at IZ = 2 mA - determines voltage stability against load current variations |
| Temperature Coefficient (SZ) | +95 mV/K at IZ = 2 mA - quantifies Zener voltage drift per degree Celsius rise |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C on ceramic substrate - sets maximum continuous operating power |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for 100 µs square wave - enables transient overvoltage suppression capability |
| Reverse Current (IR) | 50 nA at VR = 52.5 V - specifies leakage level below breakdown, critical for high-impedance nodes |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines forward conduction threshold for polarity-sensitive placement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C75 | ±5 % tolerance, higher differential resistance (200 Ω typ.), same SOD80C package | Lower accuracy; suitable only where cost outweighs regulation precision | Select when ±5 % voltage tolerance is acceptable and budget constraints dominate |
| MMSZ5265B | ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint, lower Rth(j-a) = 300 K/W) | Higher thermal performance but less precise voltage; requires PCB layout change | Choose for improved thermal margin in high-ambient-temperature environments where ±5 % is sufficient |
Compared with BZV55-B75,115, BZX55C75 trades voltage accuracy for cost, while MMSZ5265B offers better thermal handling in a different package - making the BZV55-B75,115 optimal for space-constrained, high-precision 75 V reference designs requiring ±2 % stability.

FAQ
What is the maximum continuous Zener current for BZV55-B75,115 at 25 °C?
The maximum continuous Zener current is derived from Ptot = 500 mW and VZ ≈ 75 V, yielding IZ(max) ≈ 6.7 mA. This assumes ambient temperature ≤50 °C on a ceramic substrate; derating applies above that temperature per Rth(j-a) = 380 K/W.
Can BZV55-B75,115 be used in series for higher voltage references?
No - BZV55-B75,115 is not characterized or guaranteed for series operation. Its ±2 % tolerance and positive temperature coefficient cause unpredictable voltage stacking and thermal runaway risk. Dedicated high-voltage Zeners or resistor-divider + reference ICs are recommended instead.
How does the +95 mV/K temperature coefficient affect circuit performance?
The +95 mV/K coefficient means VZ increases ~7.1 V over a 75 °C junction temperature rise. In un-compensated circuits, this causes measurable regulation drift; it must be accounted for in precision references via complementary NTC elements or digital calibration routines.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C footprint (2.30 × 4.30 mm solder lands) supports peak temperatures up to 260 °C for ≤30 seconds, with preheat ramp rates ≤3 °C/s and cooling rate ≥1 °C/s.
