Product details
Overview
BZV55-C10,135 from Nexperia is a 10 V ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 400 mW total power dissipation at Tamb ≤ 50 °C and 500 mW at Ttp ≤ 50 °C, with 200 nA reverse leakage at VR = 7 V, used for precision low-power voltage reference and regulation in analog sensor signal conditioning circuits.
For engineers reviewing the BZV55-C10,135 datasheet, BZV55-C10,135 pinout, BZV55-C10,135 application, or BZV55-C10,135 equivalent, key selection criteria include nominal Zener voltage (10 V), tolerance (±5 %), differential resistance (50–150 Ω at IZ = 5 mA), temperature coefficient (+4.5 to +8.0 mV/K), and SOD80C thermal resistance (Rth(j-a) = 380 K/W).
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and supply conditions. Its 10 V nominal working voltage is specified at IZ = 5 mA, with typical differential resistance of 100 Ω and temperature coefficient of +6.4 mV/K - indicating positive drift with junction temperature rise.
The device uses a low-capacitance silicon junction (Cd = 90 pF at f = 1 MHz, VR = 0 V) and supports non-repetitive surge handling up to 40 W for 100 µs square-wave pulses, enabling transient overvoltage clamping in low-energy protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V at IZ = 5 mA - defines regulated output range for reference design |
| Tolerance | ±5 % - determines absolute accuracy budget in voltage-sensitive feedback loops |
| Differential Resistance (rdif) | 50 Ω (min) to 150 Ω (max) at IZ = 5 mA - impacts load regulation error under current variation |
| Reverse Leakage (IR) | 200 nA at VR = 7 V - ensures minimal quiescent current draw in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard PCB layout |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - governs junction temperature rise per watt of dissipated power |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs pulse - enables short-duration overvoltage suppression without failure |
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 during Zener operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|

| Hermetically sealed glass construction | SOD80C package - ensures long-term parameter stability and moisture resistance |
| Wide operating voltage range | 10 V nominal with ±5 % tolerance - supports cost-optimized designs where tight regulation is not required |
| Low reverse leakage | 200 nA at 7 V - minimizes error in high-impedance voltage divider or reference buffer inputs |
| Controlled temperature coefficient | +6.4 mV/K typical - allows predictable drift compensation in temperature-critical analog stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240BLT1G | 10 V ±5 %, SOT-23 package, 225 mW Ptot, rdif = 17 Ω typical | Higher power density but lower surge capability (25 W max) | Select when board space is constrained and surge immunity is secondary to regulation precision |
| BZX84-C10 | 10 V ±5 %, SOT-23 package, 350 mW Ptot, rdif = 20 Ω typical, Rth(j-a) = 300 K/W | Lower thermal resistance and tighter rdif, but higher leakage (500 nA at 7 V) | Select when improved load regulation is critical and PCB layout allows better heat sinking |
Compared with BZV55-C10,135, MMBZ5240BLT1G offers superior regulation precision but reduced surge robustness, while BZX84-C10 delivers lower impedance regulation at the cost of higher reverse leakage - making BZV55-C10,135 optimal for cost-sensitive, thermally unmanaged, medium-accuracy reference applications.

FAQ
What is the maximum continuous forward current rating for BZV55-C10,135?
The BZV55-C10,135 is not intended for forward conduction; its absolute maximum forward current is 250 mA, but operation in forward bias exceeds its design intent. It is rated for reverse breakdown only, with forward voltage limited to 0.9 V at 10 mA - sufficient for ESD protection but not for rectification.
Can BZV55-C10,135 be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging and thermal runaway when paralleled. The BZV55-C10,135 has +6.4 mV/K coefficient, so mismatched units will not share current evenly; use a single higher-rated device or active regulation instead.
What is the recommended PCB footprint for SOD80C mounting?
The official Nexperia reflow soldering footprint specifies 2.30 mm × 4.30 mm solder lands with 0.90 mm spacing between pads and 4.55 mm overall length. Use IPC-7351B "SOD80C" land pattern with 0.15 mm solder mask expansion to ensure reliable thermal transfer and mechanical adhesion.
How does the 100 µs surge rating translate to real-world transient protection?
The 40 W non-repetitive peak power rating applies to single 100 µs square-wave pulses at 25 °C junction temperature. In practice, this supports clamping of 100 V/1 A transients (e.g., ISO 7637-2 Pulse 1) when combined with a series current-limiting resistor, but repeated events require derating per thermal impedance curves in Figure 1.
