Product details
Overview
BZV55-C9V1,135 from Nexperia is a 9.1 V ±5 % low-power Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 400 mW total power dissipation at Tamb ≤ 50 °C and 500 mW at Ttp ≤ 50 °C, with 500 nA reverse current at 6 V and 40 Ω typical differential resistance at IZ = 5 mA - used for precision voltage reference and local regulation in low-current analog sensor interfaces.
For engineers reviewing the BZV55-C9V1,135 datasheet, BZV55-C9V1,135 pinout, BZV55-C9V1,135 application, or BZV55-C9V1,135 equivalent, this page delivers verified electrical specs, thermal behavior, SOD80C footprint details, and validated alternatives for stable 9.1 V reference design in space-constrained industrial and consumer PCBs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 9.1 V reference across load and supply variations, with temperature coefficient of +3.8 to +7.0 mV/K (typical) and low 40 Ω differential resistance ensuring minimal output voltage drift under dynamic current conditions.
Its SOD80C package provides hermetic glass sealing for long-term stability and moisture resistance, while thermal resistance from junction to ambient is 380 K/W in free air - requiring careful layout consideration for sustained 400–500 mW operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 9.1 V ±5 % - defines regulated output voltage tolerance band for reference accuracy |
| Differential Resistance | 40 Ω (typ) at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current | 500 nA at VR = 6 V - specifies leakage level affecting high-impedance bias networks |
| Total Power Dissipation | 400 mW (Tamb ≤ 50 °C), 500 mW (Ttp ≤ 50 °C) - sets maximum continuous and pulsed thermal limits |
| Non-repetitive Peak Power | 40 W (tp = 100 μs) - defines surge handling capability for transient suppression |
| Thermal Resistance | 380 K/W (junction-to-ambient, free air) - informs required PCB copper area for thermal management |
| Forward Voltage | ≤ 0.9 V at IF = 10 mA - relevant for polarity protection or series diode use cases |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C9V1 | Same 9.1 V ±5 % rating but in larger DO-35 glass package (5.2 mm length); higher 500 mW continuous rating | Requires more board area; better suited for through-hole prototyping or higher-power derating | Select when manual assembly, higher thermal margin, or legacy DO-35 footprint compatibility is required |
| MMSZ5240B | 9.1 V ±5 % in SOD-123; 500 mW rating; 30 Ω typical rdif; 100 nA IR at 6 V | Lower leakage and tighter rdif, but plastic package lacks hermetic stability | Prefer for cost-sensitive high-volume production where long-term drift is less critical than initial accuracy |
Compared with BZV55-C9V1,135, BZX55-C9V1 offers greater thermal headroom in a through-hole format, while MMSZ5240B trades hermetic reliability for lower leakage and smaller plastic SMD footprint - choice depends on environmental robustness, layout constraints, and lifetime calibration requirements.

FAQ
What is the maximum continuous reverse current this diode can sustain?
The BZV55-C9V1,135 has an absolute maximum forward current of 250 mA, but its Zener operation is defined by reverse current. At nominal 9.1 V regulation, it is rated for continuous Zener current up to approximately 44 mA (based on 400 mW / 9.1 V), limited by thermal dissipation on standard PCB layouts.
Does this part meet RoHS and REACH compliance standards?
Yes - BZV55-C9V1,135 is manufactured by Nexperia in full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free materials per Nexperia's product declaration dated January 2011.
Can this Zener diode be used in series for higher voltage references?
Yes - multiple BZV55-C9V1,135 diodes may be connected in series to achieve higher reference voltages (e.g., two in series ≈ 18.2 V), but temperature coefficients will compound, and individual unit tolerances (±5 %) result in cumulative voltage uncertainty requiring post-calibration in precision systems.
What is the recommended soldering profile for SOD80C packaging?
Nexperia specifies reflow soldering per J-STD-020, with peak temperature ≤ 260 °C for ≤ 10 seconds. The SOD80C footprint requires 2.3 mm × 4.3 mm solder lands (per Figure 7), and wave soldering uses 2.7 mm × 4.9 mm pads with 1.9 mm track width - both defined in the 2011 datasheet revision.
