Product details
Overview
BZV55-B36,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 36 V nominal Zener voltage (±2 % tolerance), 500 mW total power dissipation, and 40 W non-repetitive peak reverse power. It delivers stable reference voltage in low-current regulation circuits such as power supply feedback paths and sensor biasing networks.
For engineers reviewing the BZV55-B36,115 datasheet, BZV55-B36,115 pinout, BZV55-B36,115 application, or BZV55-B36,115 equivalent, key selection criteria include Zener voltage accuracy (±2 %), differential resistance (80 Ω at IZ = 2 mA), temperature coefficient (+35 mV/K), and thermal resistance (300 K/W junction-to-solder-point).
Technical Context
This device operates in reverse breakdown to maintain a stable 36 V reference across load variations, with low dynamic impedance enabling precise regulation under small-signal conditions. Its ±2 % tolerance and +35 mV/K temperature coefficient are specified at IZ = 2 mA and Tj = 25 °C.
The SOD80C package provides hermetic sealing for long-term stability and moisture resistance, while its thermal resistance of 300 K/W (junction-to-solder-point) supports reliable operation up to 200 °C junction temperature under defined mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 35.3 V to 36.7 V at IZ = 2 mA - ensures tight regulation window for precision reference applications |
| Differential Resistance rdif | 80 Ω max at IZ = 2 mA - minimizes output voltage variation under load current changes |
| Temperature Coefficient SZ | +35 mV/K typical at IZ = 2 mA - quantifies voltage drift per degree Celsius for thermal design margining |
| Total Power Dissipation Ptot | 500 mW at Tamb ≤ 50 °C on ceramic substrate - defines maximum continuous DC power handling |
| Non-repetitive Peak Reverse Power PZSM | 40 W for tp = 100 μs square wave - supports transient overvoltage clamping without failure |
| Reverse Current IR | 50 nA max at VR = 25.2 V (0.7 × VZ(nom)) - ensures minimal leakage in high-impedance bias networks |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - defines conduction loss when used in forward-biased protection roles |
Pinout & Package
The BZV55-B36,115 uses the SOD80C hermetically sealed glass surface-mount package (1.60 mm × 3.70 mm × 0.30 mm), with cathode identified by a 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 reverse-bias path for regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C36,113 | ±5 % tolerance (vs. ±2 %), higher rdif (100 Ω), same SOD80C package | Lower cost for non-critical references where 36 V ±1.8 V is acceptable | Select when tighter voltage accuracy is not required and cost sensitivity dominates |
| MMSZ5241B-TP | ±5 % tolerance, SOD-123 package (larger footprint), 500 mW rating, rdif = 90 Ω | Requires PCB layout change; suitable where existing SOD-123 land pattern is standardized | Choose only if SOD-123 is mandated by assembly process or legacy board design |
Compared with BZV55-B36,115, the BZX55C36,113 trades voltage accuracy for cost, while MMSZ5241B-TP requires mechanical redesign but offers broader distributor availability-making the BZV55-B36,115 optimal for new designs demanding ±2 % stability in compact SOD80C form.

FAQ
What is the maximum continuous reverse current for BZV55-B36,115 at 25 °C?
The maximum continuous reverse current is derived from Ptot = 500 mW and VZ ≈ 36 V, yielding IZ(max) ≈ 13.9 mA. This assumes ambient temperature ≤50 °C on a ceramic substrate; derating applies above that temperature per the thermal resistance specification.
Does BZV55-B36,115 support reflow soldering, and what profile is recommended?
Yes, the SOD80C package is qualified for lead-free reflow soldering. Nexperia recommends using the JEDEC J-STD-020 profile with peak temperature ≤260 °C, ramp rate ≤3 °C/s, and time above 217 °C limited to 60–150 seconds, as validated in the official application note AN10365.
How does the temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
With a typical SZ of +35 mV/K, the Zener voltage shifts approximately +3.5 V over a 100 K rise. At IZ = 2 mA, this corresponds to ~9.7 % deviation from 36 V nominal-requiring system-level compensation or use within narrower temperature bands for high-precision applications.
Can BZV55-B36,115 replace BZV55-C36 in an existing design?
No-BZV55-C36 has ±5 % tolerance (34.2–37.8 V), while BZV55-B36 guarantees 35.3–36.7 V. Substituting may cause out-of-spec operation in circuits relying on tight voltage windows, such as ADC references or feedback loops with narrow error margins.
