Product details
Overview
BZX384-C62,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 62 V nominal breakdown voltage at 2 mA test current, 300 mW total power dissipation, and 150 °C maximum junction temperature. It provides stable reference voltage in low-power supply regulation and overvoltage protection circuits for industrial sensor interfaces and embedded microcontroller power rails.
For engineers reviewing the BZX384-C62,115 datasheet, BZX384-C62,115 pinout, BZX384-C62,115 application, or BZX384-C62,115 equivalent, this page delivers verified electrical parameters, thermal resistance values, reverse current behavior at 62 V, differential resistance under regulation, and real-world selection guidance against alternative Zener families.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a nominal VZ of 62 V at IZ = 2 mA, exhibiting a temperature coefficient of +0.05 mV/K and maximum differential resistance of 450 Ω. Its non-repetitive peak reverse current is 0.3 A under 100 μs pulse conditions.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it features Rth(j-a) = 415 K/W and Rth(j-sp) = 110 K/W, enabling reliable thermal performance in space-constrained consumer and industrial modules where precise low-current voltage clamping is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 62 V nominal at IZ = 2 mA; actual range 58 V to 66 V per ±5 % tolerance band |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on standard FR4 PCB - defines continuous DC regulation capability |
| Differential Resistance (rdif) | ≤450 Ω at IZ = 2 mA - determines output impedance and regulation stiffness under load variation |
| Reverse Current (IR) | ≤0.2 μA at VR = 49.6 V - ensures minimal leakage in standby or high-impedance bias networks |
| Non-repetitive Peak Reverse Current (IZSM) | 0.3 A for tp = 100 μs - supports transient overvoltage suppression without failure |
| Junction Temperature (Tj) | −65 °C to +150 °C - enables operation in extended-temperature industrial environments |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low-loss forward conduction when used bidirectionally or in clamp configurations |
Pinout & Package
The BZX384-C62,115 is housed in a SOD323 (SC-76) plastic surface-mount package with cathode-marked lead identification. The marking bar denotes the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode connection point for Zener operation |
| 2 | Anode (A) | Ground or low-side reference point; establishes polarity for breakdown conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % voltage tolerance | Enables cost-effective regulation where tight VZ accuracy is not critical, such as bulk supply rail clamping |
| 300 mW power rating | Supports continuous regulation in low-current applications (<2 mA typical), avoiding heatsinking in compact PCB layouts |
| SOD323 footprint | 0.6 mm × 1.35 mm body size allows placement in dense mixed-signal designs with automated pick-and-place compatibility |
| 150 °C max junction temperature | Permits reliable operation in enclosed enclosures or near heat-generating components without derating below ambient |
| 0.3 A surge current capability | Provides immunity to short-duration transients (e.g., ESD-induced spikes) without requiring external TVS devices |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller Power Rail Clamping |
|---|---|
Use Scenario: Stabilizing reference voltage for analog front-end amplifiers in 4–20 mA loop-powered sensors. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage reference, absorbing excess current to maintain fixed 62 V rail for op-amp biasing. Use Value: Delivers <1 % regulation error across −40 °C to +85 °C ambient due to predictable +0.05 mV/K temperature coefficient and low rdif. |
Use Scenario: Protecting 3.3 V or 5 V MCU I/O pins from accidental 60 V field-wiring faults in building automation controllers. IC Role / Device Role / Timing Role: Passive overvoltage clamp limiting transient energy before it reaches sensitive digital inputs. Use Value: Absorbs up to 0.3 A surges for 100 μs without degradation, preventing latch-up or gate oxide damage in downstream logic. |
| Low-Power Battery Backup Regulator | Programmable Logic Supply Stabilization |
Use Scenario: Maintaining stable bias for EEPROM write circuitry during brown-out conditions in battery-backed memory modules. IC Role / Device Role / Timing Role: Shunt regulator holding backup supply within ±2 % of 62 V while primary source drops out. Use Value: Draws only 0.2 μA leakage at 49.6 V, extending shelf life of coin-cell or supercapacitor backup sources. |
Use Scenario: Providing clean, noise-immune reference for CPLD configuration voltage monitors in programmable logic systems. IC Role / Device Role / Timing Role: Low-capacitance (≤35 pF) Zener suppressing high-frequency noise on 62 V auxiliary supplies. Use Value: Diode capacitance of ≤35 pF minimizes signal coupling into adjacent high-speed clock traces on same PCB layer. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5262BS-7-F | 62 V ±5 %, SOT-323 package, 200 mW Ptot, rdif ≤ 500 Ω | Lower power rating reduces sustained regulation margin; higher rdif increases output impedance | Select when board space permits larger SOT-323 footprint and thermal budget allows 200 mW derating |
| BZX84-C62,215 | 62 V ±5 %, SOT-23 package, 300 mW Ptot, rdif ≤ 450 Ω, Rth(j-a) = 350 K/W | Improved thermal resistance enables higher ambient operation but requires larger pad layout | Prefer for thermally demanding environments where junction temperature must stay <130 °C at full load |
Compared with MMBZ5262BS-7-F, BZX384-C62,115 offers 50 % higher power handling and identical regulation precision; versus BZX84-C62,215, it trades 65 K/W higher thermal resistance for 30 % smaller footprint-critical in ultra-dense IoT sensor nodes.

FAQ
What is the maximum reverse voltage before breakdown for BZX384-C62,115?
The guaranteed minimum breakdown voltage is 58 V at IZ = 2 mA, meaning the diode remains in high-impedance reverse state up to this threshold. Operation below 58 V ensures no significant conduction, making it suitable for precise clamping just above system operating rails.
Can BZX384-C62,115 be used in parallel for higher power dissipation?
No-Zener diodes exhibit manufacturing variations in VZ that cause current hogging when paralleled. Even with matched units, thermal runaway occurs due to positive temperature coefficient above ~5 V. Use a single higher-rated device or external current-sharing resistors if >300 mW is needed.
How does the 0.05 mV/K temperature coefficient affect long-term stability?
This low coefficient means VZ shifts only +3.1 mV over a 62 °C rise (e.g., from 25 °C to 87 °C), contributing <0.005 % drift per °C. Combined with ±5 % initial tolerance, total variation stays within ±5.3 % across full −65 °C to +150 °C range-acceptable for non-critical biasing.
Is the SOD323 package compatible with standard reflow profiles?
Yes-the SOD323 outline meets JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Recommended solder land dimensions (0.6 mm × 1.15 mm per pad) and stencil aperture design ensure reliable void-free joints without tombstoning.
