Product details
Overview
BZV55-C5V1,135 from Nexperia is a 5.1 V ±5 % tolerance Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 400 mW total power dissipation at ≤50 °C ambient, with 2 µA reverse leakage at VR = 2 V and 400–480 Ω differential resistance at IZ = 5 mA. It serves as a precision low-power reference or clamp in analog signal conditioning circuits.
For engineers reviewing the BZV55-C5V1,135 datasheet, BZV55-C5V1,135 pinout, BZV55-C5V1,135 application, or BZV55-C5V1,135 equivalent, this part supports stable voltage referencing in space-constrained industrial sensor interfaces, low-current power rail monitoring, and overvoltage protection in battery-powered instrumentation.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 5.1 V reference across its cathode-anode terminals under controlled current conditions. Its ±5 % tolerance and −0.8 to −2.7 mV/K temperature coefficient enable predictable regulation in non-critical biasing and clamping roles.
The SOD80C package delivers hermetic sealing and thermal resistance of 300 K/W (junction-to-solder point), supporting reliable operation up to 200 °C junction temperature. Non-repetitive peak reverse power dissipation is rated at 40 W for 100 µs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 5.1 V ±5 % - defines stable regulation point for low-power reference applications |
| Total Power Dissipation | 400 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard PCB layout |
| Differential Resistance | 400–480 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current | 2 µA at VR = 2 V - ensures minimal quiescent current draw in standby clamping configurations |
| Thermal Resistance (j-sp) | 300 K/W - enables thermal design margin when soldered to copper pads on FR-4 |
| Non-repetitive Peak Power | 40 W for tp = 100 µs - supports transient surge suppression in ESD-coupled signal paths |
| Package | SOD80C - hermetically sealed glass SMD outline (3.3–3.7 mm length, 1.45–1.60 mm width) for moisture-resistant mounting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C5V1 | Same 5.1 V ±5 % rating but in larger DO-35 glass axial package; 500 mW power rating | Requires through-hole mounting and more board area; better thermal mass for intermittent surges | Select when legacy through-hole assembly or higher single-pulse energy handling is required |
| MMSZ5231B | 5.1 V ±5 % in SOD-123; 500 mW rating; 170 Ω typical rdif at 20 mA | Lower dynamic impedance improves regulation under higher bias currents; less stable at sub-mA currents | Select when tighter voltage regulation under >5 mA bias is needed and SOD-123 footprint is acceptable |
Compared with BZV55-C5V1,135, BZX55-C5V1 offers higher surge robustness in axial form, while MMSZ5231B provides lower impedance at higher currents but reduced low-current stability-making BZV55-C5V1,135 optimal for low-power, space-constrained SMD references.

FAQ
What is the maximum continuous forward current for BZV55-C5V1,135?
The absolute maximum forward current is 250 mA per datasheet Table 5. However, forward conduction is not its intended operating mode; it is specified for reverse-bias Zener regulation only. Continuous forward bias above 10 mA risks exceeding thermal limits due to low VF efficiency and lack of thermal derating guidance in forward direction.
Can BZV55-C5V1,135 be used in series for higher voltage references?
No-series connection is not recommended. The BZV55-C5V1,135 has no guaranteed matching between units, and its ±5 % tolerance compounds multiplicatively. Differential resistance mismatch also causes uneven voltage division under load, leading to regulation instability and potential thermal runaway in one device.
Is this part qualified for automotive applications?
No. The BZV55-C5V1,135 is not automotive-qualified per Nexperia's legal disclaimers (Section 12.3). It lacks AEC-Q200 stress testing, and its datasheet explicitly states non-automotive qualification. For automotive use, select AEC-Q200 qualified alternatives such as PZM5.1NB or BZX84-C5V1Q.
What is the meaning of the "135" suffix in the part number?
The "135" denotes the tape-and-reel packing option: 10,000 units per reel on 4 mm pitch, 8 mm wide carrier tape, per Table 10 of the datasheet. It does not indicate electrical or package variation-only packaging format and quantity.
