Product details
Overview
BZV85-C3V6,113 from Nexperia is a medium-power axial-leaded Zener diode in hermetically sealed SOD66 (DO-41) glass package, rated for 3.6 V nominal stabilization voltage with ±5 % tolerance, 1.3 W total power dissipation at 25 °C ambient, and 60 W non-repetitive peak reverse power handling. It serves as a precision voltage reference or shunt regulator in low-to-medium current linear power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the BZV85-C3V6,113 datasheet, BZV85-C3V6,113 pinout, BZV85-C3V6,113 application, or BZV85-C3V6,113 equivalent, this part delivers stable 3.6 V regulation under 50 mA test current, features low 15 Ω differential resistance, supports operation up to 200 °C junction temperature, and maintains tight thermal coefficient control (−3.5 to −1.0 mV/K) across its operating range.
Technical Context
The BZV85-C3V6,113 operates as a silicon planar Zener diode optimized for shunt regulation in DC power rails where precise, low-drift voltage references are required below 50 mA. Its E24-standardized 3.6 V nominal Zener voltage is specified at 60 mA test current per IEC 60134 limiting values, with guaranteed breakdown behavior under both steady-state and transient surge conditions.
Thermal performance is defined with two mounting conditions: 1.3 W dissipation when leads are held at 55 °C at 4 mm from body, and 1 W when mounted on PCB with 1 cm² copper per lead. Junction-to-tie-point thermal resistance is 110 K/W, enabling predictable derating in compact board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4 V to 3.8 V at 60 mA - defines stable regulation window for 3.6 V nominal rail |
| Differential Resistance (rdif) | 15 Ω - ensures minimal output voltage shift under load current variation |
| Temperature Coefficient (SZ) | −3.5 to −1.0 mV/K - enables predictable drift compensation in temperature-sensitive designs |
| Total Power Dissipation (Ptot) | 1.3 W - supports continuous regulation in moderate-power analog stages |
| Non-repetitive Peak Reverse Power (PZSM) | 60 W at 100 µs pulse - provides transient overvoltage clamping capability |
| Forward Voltage (VF) | ≤1 V at 50 mA - allows use as polarity-sensitive clamp or dual-function rectifier/Zener |
| Junction Temperature (Tj) | −65 °C to +200 °C - enables deployment in extended-temperature industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4728A | Same 3.6 V nominal, but ±5 % tolerance achieved via tighter binning; higher 1.0 W Ptot rating (vs. 1.3 W); 10 Ω rdif | Limited to lower-temperature industrial use (Tj max 175 °C vs. 200 °C) | Select when lower differential resistance is prioritized and extended temperature operation is not required. |
| BZX55-C3V6 | Same 3.6 V nominal, ±5 % tolerance, but SOD523 package (0.8 × 0.6 mm); 0.5 W Ptot; 20 Ω rdif | Designed for space-constrained portable electronics; unsuitable for >250 mA surge events | Select only for ultra-compact PCBs where thermal mass and surge immunity are secondary to size. |
Compared with 1N4728A and BZX55-C3V6, the BZV85-C3V6,113 offers superior thermal robustness (200 °C Tj), higher surge capacity (60 W), and better thermal resistance management (110 K/W Rth(j-t)), making it optimal for high-reliability industrial power conditioning where long-term stability under thermal cycling is critical.

FAQ
What is the maximum continuous forward current for BZV85-C3V6,113?
The absolute maximum forward current is 500 mA per IEC 60134 limiting values. However, sustained operation above 50 mA requires thermal derating based on PCB copper area and ambient temperature; typical design practice limits continuous forward conduction to ≤100 mA with adequate heatsinking to avoid exceeding 200 °C junction temperature.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified SZ of −3.5 to −1.0 mV/K, the BZV85-C3V6,113 exhibits negative temperature drift: its Zener voltage decreases by 1–3.5 mV per Kelvin rise. Over a −40 °C to +125 °C range, this results in a total shift of −0.16 V to −0.44 V, which must be compensated in high-accuracy references using external circuitry or calibration.
Can BZV85-C3V6,113 replace a 3.3 V Zener in existing designs?
No - the BZV85-C3V6,113 is specified for 3.6 V nominal regulation (3.4–3.8 V range), not 3.3 V. Substituting it for a 3.3 V Zener would raise the regulated voltage by ~0.3 V, potentially violating downstream IC input tolerances. Use BZV85-C3V3 for 3.3 V applications.
What is the significance of the "113" suffix in the part number?
The "113" is Nexperia's packaging and reel code indicating bulk packaging in tape-and-reel format compatible with automated SMT placement equipment. It does not affect electrical characteristics - all BZV85-C3V6 variants share identical Zener parameters, thermal ratings, and package dimensions regardless of suffix.
