Product details
Overview
BZV55-C15,135 from Nexperia is a 15 V ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 400 mW total power dissipation at ≤50 °C ambient and 50 nA reverse leakage at 0.7×VZ, used for precision low-power voltage reference and regulation in analog sensor signal conditioning circuits.
For engineers reviewing the BZV55-C15,135 datasheet, BZV55-C15,135 pinout, BZV55-C15,135 application, or BZV55-C15,135 equivalent, this page delivers verified electrical parameters, thermal behavior under pulsed load, differential resistance (75 Ω typ. at IZ = 5 mA), temperature coefficient (+9.2 mV/K typ.), and SOD80C footprint compatibility for PCB layout validation.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 15 V output across varying load currents (IZ = 1–5 mA), with low differential resistance (75 Ω typ.) ensuring minimal voltage deviation under dynamic current changes. Its temperature coefficient of +9.2 mV/K indicates predictable positive drift with junction heating, enabling compensation in reference designs.
Designed for low-power regulation, it supports non-repetitive surge handling up to 40 W for 100 µs pulses and exhibits 50 nA reverse leakage at VR = 10.5 V (0.7×15 V), critical for battery-powered systems requiring ultra-low standby current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 15 V nominal, ±5 % tolerance (13.8–15.6 V range); defines stable regulation point for biasing or reference generation |
| Differential Resistance | 75 Ω typical at IZ = 5 mA; determines output impedance and voltage stability under load variation |
| Reverse Leakage Current | 50 nA max at VR = 10.5 V (0.7×VZ); ensures negligible quiescent current in always-on monitoring circuits |
| Total Power Dissipation | 400 mW at Tamb ≤ 50 °C; sets maximum continuous DC power handling on standard FR-4 PCB |
| Non-repetitive Peak Power | 40 W for 100 µs square wave; enables transient overvoltage clamping without failure |
| Temperature Coefficient | +9.2 mV/K typical at IZ = 5 mA; quantifies voltage drift per degree, essential for temperature-compensated references |
| Forward Voltage | 0.9 V max at IF = 10 mA; defines anode-cathode drop when used in forward conduction (e.g., ESD protection) |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height; cathode marked by band; optimized for reflow soldering with 4 mm tape pitch.
| 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 reverse-bias path for regulation current |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective selection for applications where tight regulation is not required, such as supply rail decoupling |
| Low 75 Ω differential resistance | Minimizes output voltage shift under ±1 mA load current change, improving reference accuracy in ADC bias networks |

FAQ
What is the maximum continuous power dissipation for BZV55-C15,135 at 70 °C ambient?
At 70 °C ambient, the BZV55-C15,135 derates linearly from its 400 mW rating at 50 °C. With a thermal resistance of 380 K/W (junction-to-ambient), the device reaches its 200 °C absolute maximum junction temperature at approximately 263 mW - confirmed by Nexperia's derating curve in Section 5 of the datasheet Rev. 5.
Can BZV55-C15,135 be used in series to achieve higher Zener voltage?
No - BZV55-C15,135 is not characterized for series operation. Its specified parameters assume single-diode use. Series connection introduces mismatched temperature coefficients and leakage currents that cause uneven voltage division and potential thermal runaway, violating IEC 60134 limiting values.
Is the SOD80C package compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia specifies full compatibility with IPC/JEDEC J-STD-020D reflow profiles. The SOD80C outline (Fig 6) and solder land pattern (Fig 7) are validated for peak temperatures up to 260 °C, with thermal resistance data confirming safe operation under JEDEC-defined ramp rates and dwell times.
How does the +9.2 mV/K temperature coefficient impact accuracy in a 0–70 °C operating range?
Over 0–70 °C, the coefficient causes a +644 mV total drift (9.2 × 70), or ±4.3 % of 15 V. This is within the ±5 % initial tolerance band, meaning the full-temperature variation remains bounded by ±9.3 % - acceptable for non-precision regulation but requiring compensation in metrology-grade references.
