Product details
Overview
PZU3.6BA,115 from Nexperia is a general-purpose Zener voltage regulator diode in SOD323 (SC-76) package, designed for precision voltage reference and overvoltage protection in low-power analog and digital circuits. It delivers a nominal Zener voltage of 3.6 V with ±5 % tolerance (B series), differential resistance ≤90 Ω at IZ = 5 mA, reverse current ≤5 µA at VR = 1 V, and operates up to 150 °C junction temperature - enabling stable regulation in compact power management stages of IoT sensors and portable battery-powered devices.
For engineers reviewing the PZU3.6BA,115 datasheet, PZU3.6BA,115 pinout, PZU3.6BA,115 application, or PZU3.6BA,115 equivalent, key selection criteria include its 3.6 V nominal Zener voltage with hard breakdown knee, low dynamic impedance at low currents, compatibility with FR4 PCB mounting (single-sided copper, standard footprint), and suitability for space-constrained voltage clamping and reference functions in consumer and industrial electronics.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its cathode–anode terminals under varying load and supply conditions. Its design emphasizes low leakage (≤5 µA at 1 V), tight voltage tolerance (±5 %), and predictable temperature coefficient (−2.4 mV/K at IZ = 5 mA), supporting accurate biasing and regulation in low-current signal chains.
The device features a hard breakdown knee and very low dynamic impedance (≤90 Ω), ensuring minimal voltage deviation during transient load changes. Thermal resistance from junction to ambient is 390 K/W on standard FR4, limiting continuous power dissipation to 320 mW at Tamb ≤ 25 °C - consistent with its role in non-switching, low-duty-cycle protection and reference applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal, ±5 % tolerance - defines precise clamping/reference level for 3.3 V rail stabilization and logic-level protection |
| Differential Resistance (rdif) | ≤90 Ω at IZ = 5 mA - ensures minimal output voltage shift under small load variations |
| Reverse Current (IR) | ≤5 µA at VR = 1 V - enables low-quiescent-current operation in battery-sensitive designs |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling in surface-mounted layout |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - supports surge suppression for ESD or transient events without degradation |
| Junction Temperature (Tj) | −55 °C to +150 °C - allows reliable operation in extended-temperature industrial environments |
| Package | SOD323 (SC-76), 1.7 mm × 1.25 mm × 0.95 mm - enables high-density placement in miniaturized PCB assemblies |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Enables sharp, predictable turn-on at 3.6 V - critical for accurate voltage clamping without soft saturation |
| Very low dynamic impedance | ≤90 Ω at 5 mA - minimizes output voltage ripple under dynamic load steps in reference circuits |
| Low reverse leakage | ≤5 µA at 1 V - preserves battery life and avoids unintended loading in always-on sensor nodes |
| High surge capability | 40 W non-repetitive peak power - absorbs short-duration transients without permanent parameter shift |
| Extended temperature range | Operates from −55 °C to +150 °C - suitable for automotive under-hood and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6,115 | Same 3.6 V ±5 %, SOD323 package, but higher typical rdif (120 Ω vs. 90 Ω) and higher IR (10 µA vs. 5 µA) | Less suitable for ultra-low-leakage reference use; acceptable for basic clamping where tighter impedance not required | Select when cost sensitivity outweighs need for lowest dynamic impedance and leakage |
| MMSZ4685T1G | 3.6 V ±5 %, SOD-123 package (larger footprint), rdif ≤100 Ω, IR ≤10 µA at 1 V | Requires PCB redesign due to different pad layout; thermal resistance ~300 K/W (better than PZU3.6BA's 390 K/W) | Choose if higher power derating margin or legacy SOD-123 footprint compatibility is prioritized |
Compared with BZX384-B3V6,115 and MMSZ4685T1G, PZU3.6BA,115 offers the lowest combination of differential resistance and reverse leakage in the SOD323 form factor, making it optimal for high-precision, space-constrained reference and clamping where minimal voltage deviation and ultra-low standby current are critical.

FAQ
What is the maximum continuous forward current for PZU3.6BA,115?
The device is rated for a maximum forward current (IF) of 200 mA per Absolute Maximum Ratings (Table 5). However, it is intended for reverse-bias Zener operation; forward conduction is only relevant during circuit power-up sequencing or fault conditions, not steady-state regulation.
Can PZU3.6BA,115 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and manufacturing spread, causing current imbalance and thermal runaway when paralleled. For higher power, use a single higher-rated Zener or an active regulator; do not parallel PZU3.6BA,115 units.
How does the −2.4 mV/K temperature coefficient affect regulation accuracy?
At IZ = 5 mA, the Zener voltage decreases by 2.4 mV per Kelvin rise in junction temperature. Over a 100 °C range (25 °C to 125 °C), this yields ~240 mV drift - requiring thermal design mitigation (e.g., heatsinking, layout isolation) for applications demanding <±1 % voltage stability.
Is PZU3.6BA,115 suitable for automotive applications?
No - this part is not AEC-Q200 qualified and lacks automotive-grade screening, qualification testing, or guaranteed performance across −40 °C to +125 °C extended temperature range. Use Nexperia's automotive-qualified Zener series (e.g., PZUxHBA) for vehicle applications.
