Product details
Overview
BZX8850-B3V6YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 3.6 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 μA test current, features 95 Ω differential resistance at 5 mA, and operates within −55 °C to +150 °C ambient range. Used in battery-powered sensor biasing and low-power microcontroller reset circuits.
For engineers reviewing the BZX8850-B3V6YL datasheet, BZX8850-B3V6YL pinout, BZX8850-B3V6YL application, or BZX8850-B3V6YL equivalent, key selection criteria include its ultra-low test current specification, tight 2 % voltage tolerance, DFN1006-2 footprint compatibility, and thermal resistance of 500 K/W on FR4 PCB.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 3.6 V at IZ = 50 μA, exhibiting a temperature coefficient of −3.5 mV/K and diode capacitance of 160 pF at 0 V. Its differential resistance drops to 95 Ω at 5 mA, supporting stable regulation under light load conditions.
The device uses a silicon planar epitaxial process optimized for low-leakage performance and fast transient response. Its intentional minor leakage rise (per AN90031) reduces noise and improves switching behavior in signal conditioning paths without compromising regulation accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.53 V to 3.67 V at IZ = 50 μA - ensures precise 3.6 V reference under ultra-low bias |
| Tolerance | ±2 % - enables high-accuracy voltage clamping in portable analog front-ends |
| Differential Resistance (rdiff) | 95 Ω at IZ = 5 mA - maintains regulation stability across small load variations |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - supports bidirectional protection or dual-use as clamp diode |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - limits thermal rise in space-constrained SMD layouts |
| Junction Temperature (Tj) | 150 °C maximum - allows operation in industrial-grade environments without derating |
| Thermal Resistance (Rth(j-a)) | 500 K/W on FR4 PCB - defines thermal path efficiency for passive cooling designs |

FAQ
What is the maximum reverse current (IR) at 3.0 V for BZX8850-B3V6YL?
At VR = 3.0 V and Tamb = 25 °C, the typical reverse current is 0.8 µA, with a maximum of 2.0 µA per Table 8. This low leakage ensures minimal parasitic loading on high-impedance bias networks in sensor interfaces and reset circuits.
Can BZX8850-B3V6YL be used in place of a 3.3 V Zener diode?
No - its nominal Zener voltage is 3.6 V (range 3.53–3.67 V), not 3.3 V. Substituting it for a 3.3 V part would raise the regulated voltage by ~300 mV, potentially exceeding IC absolute maximum ratings. Use BZX8850-B3V3 (3.3 V) instead.
Is the cathode marking visible under optical inspection?
Yes - the cathode is indicated by a laser-marked bar on the top surface of the DFN1006-2 package, aligned with Pin 1 per Figure 9. This marking remains legible after reflow soldering and supports automated optical inspection (AOI) in high-volume assembly.
Does BZX8850-B3V6YL meet AEC-Q200 requirements?
No - this device is not automotive-qualified. Nexperia explicitly states in Section 14 that non-automotive qualified products like BZX8850-B3V6YL are unsuitable for safety-critical or automotive applications unless separately validated by the customer.
