Product details
Overview
BZX84J-C62,115 from Nexperia is a 62 V ±5 % tolerance Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and overvoltage protection in low-power analog and automotive circuits. It delivers 550 mW total power dissipation, 44 Ω typical differential resistance at IZ = 2 mA, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the BZX84J-C62,115 datasheet, BZX84J-C62,115 pinout, BZX84J-C62,115 application, or BZX84J-C62,115 equivalent, key selection criteria include Zener voltage tolerance, non-repetitive surge capability (IZSM = 0.3 A), thermal resistance (Rth(j-a) = 230 K/W), and automotive-grade reliability validation.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage across load variations and supply fluctuations. Its 62 V nominal working voltage is specified at IZ = 2 mA with ±5 % tolerance, and exhibits a positive temperature coefficient of +71.6 mV/K at that test current.
The device supports pulsed surge conditions up to 40 W (tp = 100 μs, square wave), with maximum non-repetitive peak reverse current of 0.3 A. Junction-to-ambient thermal resistance is 230 K/W on FR4 PCB, enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V nominal, ±5 % tolerance at IZ = 2 mA - defines precise clamping threshold for protection and reference circuits |
| Differential Resistance (rdiff) | 44 Ω typical at IZ = 2 mA - determines regulation stiffness and output impedance in shunt regulator designs |
| Total Power Dissipation (Ptot) | 550 mW at Tamb ≤ 25 °C - sets continuous DC power limit on standard FR4 PCB with 1 cm² cathode pad |
| Non-repetitive Peak Reverse Current (IZSM) | 0.3 A at tp = 100 μs - enables transient overvoltage suppression without device failure |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - ensures low conduction loss when used in series forward-biased configurations |
| Reverse Leakage (IR) | 0.05 μA max at VR = 49.6 V - guarantees minimal quiescent current in high-impedance bias networks |
| Junction Temperature (Tj) | 150 °C maximum - supports operation in under-hood automotive environments and industrial enclosures |
Pinout & Package
SOD323F (SC-90) surface-mount plastic package: 2-terminal, ultra-compact footprint (2.7 × 1.35 mm), flat lead profile optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C62,115 | Same 62 V ±5 % rating but not AEC-Q101 qualified; higher rdiff (50 Ω typ.) and lower IZSM (0.25 A) | Limited to commercial-grade consumer and industrial equipment without automotive qualification requirements | Select when cost sensitivity outweighs automotive reliability needs and surge margin is less critical |
| MMSZ5257B-7-F | 62 V ±5 %, SOD-123 package (larger footprint), 500 mW Ptot, rdiff = 55 Ω, no AEC-Q101 certification | Compatible with legacy SOD-123 layouts but lacks automotive qualification and has higher thermal resistance | Choose only for drop-in replacement in existing SOD-123 designs where AEC-Q101 is not mandated |
Compared with BZX84-C62,115 and MMSZ5257B-7-F, the BZX84J-C62,115 uniquely combines AEC-Q101 qualification, lowest rdiff (44 Ω), and highest IZSM (0.3 A) in the smallest SOD323F package - making it optimal for space-constrained, high-reliability automotive and industrial systems.

FAQ
What is the maximum continuous power dissipation for BZX84J-C62,115?
The BZX84J-C62,115 has a total power dissipation (Ptot) of 550 mW at ambient temperature ≤ 25 °C when mounted on an FR4 PCB with a 1 cm² cathode copper pad. Derating is required above 25 °C at 4.4 mW/°C, based on its 230 K/W junction-to-ambient thermal resistance.
Is BZX84J-C62,115 suitable for automotive applications?
Yes - the BZX84J-C62,115 is fully qualified to AEC-Q101 standards for discrete semiconductors, including stress testing for temperature cycling, humidity, and mechanical shock. It operates reliably from −55 °C to +150 °C junction temperature, meeting requirements for under-hood and cabin electronics.
How does the Zener voltage tolerance affect circuit performance?
The ±5 % tolerance (C-series) means the actual VZ falls between 58.9 V and 65.1 V at IZ = 2 mA. This impacts precision reference accuracy and overvoltage clamp thresholds; for tighter regulation, the BZX84J-B62,115 (±2 %) variant offers 60.8–63.2 V range but at higher cost and slightly reduced surge capability.
What is the significance of the SOD323F package in layout design?
The SOD323F (SC-90) package measures 2.7 × 1.35 mm with 0.65 mm lead pitch, enabling ultra-dense placement and compatibility with fine-pitch reflow processes. Its flat lead structure reduces tombstoning risk, and the cathode marking bar simplifies optical inspection and automated orientation verification during SMT assembly.
