Product details
Overview
BZX384-B62F from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 62 V nominal breakdown voltage at 5 mA, 300 mW total power dissipation, and 150 °C maximum junction temperature. It serves as a precision reference or overvoltage clamp in low-power analog supply rails and sensor interface circuits.
For engineers reviewing the BZX384-B62F datasheet, BZX384-B62F pinout, BZX384-B62F application, or BZX384-B62F equivalent, key selection criteria include its 62 V Zener voltage with ±2 % tolerance, differential resistance of 450 Ω at 5 mA, reverse current ≤3 μA at 49.6 V, and thermal resistance of 110 K/W from junction to solder point - all critical for stable biasing and transient suppression in space-constrained designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its 62 V nominal Zener voltage is specified at IZ = 5 mA, with a temperature coefficient of +43.4 mV/K and differential resistance of 450 Ω, indicating moderate regulation sensitivity to current changes.
The device features non-repetitive peak reverse power dissipation up to 40 W for 100 μs pulses and is qualified for operation from −65 °C to +150 °C ambient. Mounting on FR4 PCB with standard SOD323 footprint yields Rth(j-a) = 415 K/W and Rth(j-sp) = 110 K/W, enabling reliable thermal performance in compact consumer and industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V nominal at IZ = 5 mA; ±2 % tolerance ensures tight regulation for reference applications |
| Differential Resistance (rdif) | 450 Ω max at IZ = 5 mA; defines voltage change per mA shift in Zener current |
| Reverse Current (IR) | ≤3 μA at VR = 49.6 V; guarantees low leakage before breakdown onset |
| Total Power Dissipation (Ptot) | 300 mW at Tamb ≤ 25 °C on FR4 PCB; sets continuous DC power limit |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs; supports surge clamping without damage |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA; enables use as low-drop rectifier or ESD path in forward bias |
| Junction Temperature (Tj) | 150 °C max; determines maximum allowable internal operating temperature under power stress |

Applications
| Power Supply Reference | Sensor Biasing |
|---|---|
|
Use Scenario: Providing stable 62 V reference for high-side current sensing amplifier bias in 72 V battery management systems. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, absorbing excess current to hold node voltage constant. Use Value: ±2 % tolerance and 450 Ω dynamic impedance ensure reference drift remains under ±1.24 V across 1–10 mA load variation. |
Use Scenario: Generating precise bias voltage for piezoresistive pressure sensor excitation in HVAC control modules. IC Role / Device Role / Timing Role: Functions as passive voltage clamp to protect sensor bridge from overvoltage during startup transients. Use Value: 40 W surge rating absorbs 100 μs, 2 A transient events without degradation, eliminating need for discrete TVS. |
| Overvoltage Protection | Signal Level Translation |
|
Use Scenario: Clamping CAN bus node supply rail against load-dump spikes in automotive body electronics. IC Role / Device Role / Timing Role: Shunt regulator diverts surge current when rail exceeds 62 V, limiting downstream IC exposure. Use Value: 150 °C junction rating allows operation in under-hood environments where ambient reaches 125 °C. |
Use Scenario: Level-shifting 3.3 V microcontroller GPIO to interface with 62 V industrial fieldbus receivers. IC Role / Device Role / Timing Role: Reverse-biased Zener establishes 62 V threshold for open-drain signal detection. Use Value: 3 μA reverse leakage at 49.6 V ensures negligible quiescent current draw in standby state. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5262B | 62 V, ±5 % tolerance, 350 mW Ptot, SOT-23 package | Higher power but looser tolerance; larger footprint requires more PCB area | Select when higher surge margin is needed and ±5 % regulation error is acceptable |
| Vishay BZX384-C62 | 62 V, ±5 % tolerance, same SOD323 package, 300 mW Ptot | Same form factor but wider voltage spread (58–66 V); less precise reference | Choose for cost-sensitive designs where 62 V ±5 % meets system accuracy requirements |
Compared with BZX384-B62F, MMBZ5262B offers higher power handling but sacrifices tolerance and package compactness, while BZX384-C62 retains identical footprint and power rating but trades ±2 % precision for lower unit cost - making BZX384-B62F optimal for space-constrained, accuracy-critical 62 V references.

FAQ
What is the Zener test current for BZX384-B62F?
The nominal Zener voltage of 62 V is specified at a test current of 5 mA, as defined in Table 8 of the datasheet. This current level balances measurement stability and self-heating effects, and must be maintained during calibration or reference design verification.
Can BZX384-B62F be used in series for higher voltage regulation?
No - BZX384-B62F is not characterized or guaranteed for series operation. Zener impedance mismatch between units causes uneven voltage division, risking thermal runaway in one device. Use a single higher-voltage Zener or active regulation instead.
Is BZX384-B62F automotive-qualified?
No - this part is non-automotive qualified per Revision 4 (January 2023) datasheet. Nexperia explicitly states that BZX384-B62F is not tested to AEC-Q200 and should not be used in safety-critical or automotive applications without additional qualification.
How does the marking code 'N7' identify BZX384-B62F?
Per Table 4, 'N7' is the unique top-side marking for BZX384-B62F. The 'N' prefix denotes the BZX384-B series (±2 % tolerance), and '7' corresponds to the 62 V variant within that series - enabling visual identification on assembled PCBs.
