Product details
Overview
BZV55-B9V1,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 9.1 V nominal regulation at 5 mA with ±2 % tolerance, 40 Ω typical differential resistance, and 3.8 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks for power supply feedback, sensor excitation, and analog signal conditioning in industrial control modules.
For engineers reviewing the BZV55-B9V1,115 datasheet, BZV55-B9V1,115 pinout, BZV55-B9V1,115 application, or BZV55-B9V1,115 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge (100 µs, 40 W), reverse leakage (500 nA at 6 V), and SOD80C footprint compatibility for PCB layout validation.
Technical Context
This Zener diode operates in reverse breakdown to maintain a precise DC reference voltage across its terminals under varying load and temperature conditions. Its 9.1 V nominal Zener voltage is specified at IZ = 5 mA, with low differential resistance (40–100 Ω) ensuring minimal output variation with current changes.
The device exhibits a positive temperature coefficient of +3.8 mV/K at 5 mA, enabling predictable drift compensation in multi-diode reference strings. Its hermetic glass SOD80C package supports reflow and wave soldering per JEDEC standards, with Rth(j-a) = 380 K/W in free air and Rth(j-sp) = 300 K/W to solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.92 V to 9.28 V at IZ = 5 mA - defines tight ±2 % regulation window for precision biasing |
| Differential Resistance (rdif) | 40 Ω typical at IZ = 5 mA - ensures <10 mV output shift per 1 mA load change |
| Reverse Leakage (IR) | 500 nA max at VR = 6 V - enables ultra-low quiescent current in battery-powered references |
| Power Dissipation (Ptot) | 500 mW max at Tamb ≤ 50 °C - supports continuous operation in compact SMT layouts |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - withstands ESD and switching transients without degradation |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - limits junction rise to ~190 °C at full 500 mW dissipation |
| Capacitance (Cd) | 150 pF max at f = 1 MHz, VR = 0 V - negligible impact on >1 MHz signal integrity in bypass roles |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height; cathode indicated by marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for controlled current flow |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in circuits requiring tighter regulation than standard ±5 % parts |
| Hermetic glass SMD construction | Prevents moisture ingress and long-term parameter drift in humid or high-reliability environments |
| Low 40 Ω differential resistance | Reduces output voltage error to <0.5 % over 1–10 mA operating range |
| Positive 3.8 mV/K tempco | Allows pairing with negative-tempco components (e.g., silicon diodes) for compensated references |
| 40 W non-repetitive surge rating | Survives IEC 61000-4-2 ESD events without parameter shift or failure |
Applications
| Power Supply Feedback | Sensor Excitation Reference |
|---|---|
|
Use Scenario: Provides stable 9.1 V reference for optocoupler-based feedback in isolated AC/DC adapters. IC Role / Device Role / Timing Role: Zener diode establishes precise voltage threshold that triggers TL431 or shunt regulator conduction. Use Value: Maintains ±1 % output regulation across line/load variations due to tight VZ tolerance and low rdif. |
Use Scenario: Supplies excitation voltage to resistive temperature detectors (RTDs) in industrial process transmitters. IC Role / Device Role / Timing Role: Acts as low-noise, low-drift voltage source for constant-current generation via op-amp circuitry. Use Value: Enables 0.1 °C temperature resolution by limiting reference drift to <0.05 %/°C over 0–70 °C. |
| Analog Signal Clamping | Microcontroller Reset Circuit |
|
Use Scenario: Limits input voltage swing to protect ADC inputs from overvoltage during transient coupling. IC Role / Device Role / Timing Role: Functions as bidirectional clamp: forward conducts at 0.9 V, reverse regulates at 9.1 V. Use Value: Prevents latch-up in 3.3 V/5 V microcontrollers by clamping signals between –0.3 V and 9.5 V. |
Use Scenario: Generates clean reset pulse for ARM Cortex-M MCUs during power-up sequencing. IC Role / Device Role / Timing Role: Zener sets threshold for RC-delayed reset assertion; paired with transistor for active-low reset. Use Value: Ensures reliable reset deassertion only after VCC exceeds 8.7 V, avoiding brown-out instability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C9V1 | ±5 % tolerance (9.1 V ±0.46 V), higher rdif (100 Ω typ), same SOD80C package | Acceptable where cost sensitivity outweighs regulation accuracy; unsuitable for <1 % feedback loops | Select when budget constraints dominate and system-level calibration compensates for wider VZ spread |
| MMSZ5240B | ±5 % tolerance, 500 mW rating, SOD-123 package (larger footprint, higher Rth(j-a) = 500 K/W) | Requires PCB redesign; thermal performance inferior in dense layouts | Choose only if legacy SOD-123 footprint must be retained and derating to 300 mW is acceptable |
Compared with BZV55-B9V1,115, BZX55C9V1 trades regulation precision for lower unit cost, while MMSZ5240B sacrifices thermal efficiency and board space for broader distributor availability-neither matches the 9.1 V ±2 % stability and SOD80C thermal profile of the original.

FAQ
What is the maximum continuous forward current for BZV55-B9V1,115?
The absolute maximum forward current is 250 mA per Table 5. However, sustained forward conduction is not a functional operating mode-this rating ensures robustness during handling, soldering, or accidental polarity reversal. Normal operation is strictly in reverse-bias Zener breakdown.
Can BZV55-B9V1,115 be used in series for higher voltage references?
Yes-its ±2 % tolerance and matched temperature coefficient enable predictable stacking. Two devices yield 18.2 V ±2.8 %, with total differential resistance ~80 Ω. Thermal coupling on the same pad improves tracking, reducing net tempco drift versus independent placement.
How does the 40 W non-repetitive peak power rating translate to real-world surge immunity?
This rating corresponds to a 100 µs, 40 W square-wave pulse (e.g., 200 V × 0.2 A). It exceeds IEC 61000-4-2 Level 4 (15 kV air, 8 kV contact) ESD requirements, confirming survivability against common board-level electrostatic discharges without parameter shift.
Is the SOD80C package compatible with standard reflow profiles?
Yes-the device is qualified for lead-free reflow per J-STD-020. The recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s pre- and post-peak. Figure 7 provides the exact solder land pattern (2.30 mm × 4.30 mm) for optimal wetting and void minimization.
