Product details
Overview
BZX84J-B62,115 from Nexperia is a 62 V ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 550 mW total power dissipation and 40 W non-repetitive peak reverse power at tp = 100 µs, used for precision voltage regulation and overvoltage protection in automotive and industrial power rails.
For engineers reviewing the BZX84J-B62,115 datasheet, BZX84J-B62,115 pinout, BZX84J-B62,115 application, or BZX84J-B62,115 equivalent, this page delivers verified Zener voltage, differential resistance, thermal resistance, AEC-Q101 qualification status, and cathode/anode terminal mapping - all confirmed from Nexperia's Rev. 3 (2025) product data sheet.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 62 V at IZ = 2 mA, exhibiting a temperature coefficient of +71.6 mV/K and differential resistance of 400 Ω at the same test current. Its low 55 K/W junction-to-solder-point thermal resistance enables stable regulation under transient surge conditions.
The device complies with AEC-Q101 for automotive use and features a maximum reverse current of 0.05 µA at VR = 50 V, ensuring minimal leakage in standby power circuits. Its SC-90 package supports high-density surface-mount layouts while maintaining thermal performance on FR4 PCBs with standard tin-plated copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 60.8 V to 63.2 V at IZ = 2 mA - defines precise clamping threshold for 62 V nominal rail protection |
| Tolerance | ±2 % - ensures tight voltage control for safety-critical regulation without post-production trimming |
| 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 Power (PZSM) | 40 W at tp = 100 µs - supports ESD/surge suppression in automotive load-dump scenarios |
| Differential Resistance (rdiff) | 400 Ω at IZ = 2 mA - determines regulation stiffness and output impedance under dynamic load changes |
| Thermal Resistance (Rth(j-sp)) | 55 K/W - enables accurate junction temperature estimation from solder point measurement during thermal design |
| Reverse Current (IR) | ≤ 0.05 µA at VR = 50 V - guarantees ultra-low standby leakage in battery-backed systems |
Pinout & Package
SOD323F (SC-90) plastic surface-mounted package: 2-terminal, ultra-small outline (2.7 × 1.35 mm), flat lead, cathode-marked with bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse breakdown current |
| 2 | Anode (A) | Connected to reference or ground potential; forms the return path during Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards |
| Low differential resistance | 400 Ω at 2 mA - minimizes output voltage deviation across load current variations in feedback paths |
| Stable temperature coefficient | +71.6 mV/K - enables predictable voltage drift compensation in wide-temperature-range applications |
| Ultra-low reverse leakage | ≤ 0.05 µA at 50 V - preserves battery life in always-on vehicle modules and IoT edge sensors |
| Pulsed surge capability | 40 W non-repetitive peak power - absorbs ISO 7637-2 pulse 1/2/5a transients without degradation |
Applications

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 | ±5 % tolerance, higher IR (0.05 µA vs. ≤0.05 µA), identical package and PZSM | Acceptable where cost sensitivity outweighs precision; less suitable for high-accuracy feedback loops | Select when tighter voltage tolerance is not required and BOM cost reduction is prioritized |
| MMSZ5257ET1G | 62 V ±5 %, SOD-123 package (larger footprint), 500 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade applications; incompatible with automotive thermal and reliability requirements | Choose only for non-automotive designs where SC-90 size constraint does not apply |
Compared with BZX84J-B62,115, the BZX84-C62,115 trades voltage precision for lower unit cost, while MMSZ5257ET1G sacrifices automotive qualification and board space efficiency - making the BZX84J-B62,115 optimal for space-constrained, safety-critical 62 V regulation where ±2 % tolerance and AEC-Q101 compliance are mandatory.

FAQ
What is the maximum continuous forward current for BZX84J-B62,115?
The absolute maximum forward current (IF) is 250 mA per Nexperia's limiting values table. However, forward conduction is not its intended operating mode; sustained forward bias above 100 mA risks thermal overstress due to VF ≈ 1.1 V and limited Ptot = 550 mW. It should be operated exclusively in reverse breakdown for regulation.
Does BZX84J-B62,115 support reflow soldering only, or can it be hand-soldered?
Nexperia specifies reflow soldering as the only recommended method. Hand-soldering is not advised due to the SOD323F package's small thermal mass and sensitivity to localized overheating; exceeding 260 °C at the leads for >10 seconds risks delamination or parameter shift. Reflow profile must follow JEDEC J-STD-020 guidelines for MSN Level 1.
How does the +71.6 mV/K temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
Over that range, the Zener voltage shifts by approximately +5.4 V (71.6 mV/K × 75 K), resulting in a final VZ ≈ 67.4 V at +125 °C. This drift is fully characterized and repeatable; designers compensate using resistor-divider feedback or select complementary-coefficient diodes in series for net-zero TC designs.
Is the 40 W non-repetitive peak power rating valid at elevated junction temperatures?
No - the 40 W rating applies only when Tj = 25 °C prior to surge, as defined in Table 8 notes. At higher pre-surge temperatures, derating is required: Fig. 1 shows PZSM drops to ~10 W at Tj = 150 °C. For reliable surge handling, thermal design must ensure junction temperature remains near ambient before transient events.
