Product details
Overview
BZV85-C4V7,113 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 4.7 V nominal stabilization voltage with ±5 % tolerance, 1.3 W total power dissipation at Ttp = 55 °C, 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 supplies and overvoltage protection circuits.
For engineers reviewing the BZV85-C4V7,113 datasheet, BZV85-C4V7,113 pinout, BZV85-C4V7,113 application, or BZV85-C4V7,113 equivalent, key selection criteria include its 4.4–5.0 V working voltage range, 45 Ω typical differential resistance at 3 mA test current, −2.0 to +0.7 mV/K temperature coefficient, 1800 pF capacitance at 0 V, and 1.8 mA maximum reverse leakage at 3.76 V - all critical for stable DC biasing and noise-sensitive analog references.
Technical Context
The BZV85-C4V7,113 operates as a silicon planar Zener diode utilizing controlled avalanche and Zener breakdown mechanisms. Its voltage regulation is specified at Itest = 3 mA, with a nominal VZ of 4.7 V and differential resistance rdif ≤ 45 Ω, enabling tight regulation under varying load conditions.
Thermal performance is defined by Rth(j-t) = 110 K/W (junction-to-tie-point, 4 mm lead length) and Rth(j-a) = 175 K/W (junction-to-ambient, 10 mm leads), supporting operation up to Tj = 200 °C. The device exhibits a negative-to-slightly-positive temperature coefficient (−2.0 to +0.7 mV/K), optimized for stability near 4.7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 4.7 V (range: 4.4–5.0 V at Itest = 3 mA; defines stable reference point for shunt regulation) |
| Power Dissipation | 1.3 W max (at Ttp = 55 °C, 4 mm from body; enables sustained operation in compact PCB layouts) |
| Differential Resistance | ≤45 Ω (at Itest = 3 mA; ensures <15 mV output variation per 1 mA load change) |
| Temperature Coefficient | −2.0 to +0.7 mV/K (at Itest = 3 mA; supports predictable drift compensation in temperature-varying environments) |
| Reverse Capacitance | 1800 pF (at f = 1 MHz, VR = 0 V; impacts high-frequency filtering and transient response in feedback paths) |
| Peak Reverse Current | 1.8 A (non-repetitive, tp = 100 µs; provides surge immunity against short-duration transients) |
| Forward Voltage | ≤1.0 V (at IF = 50 mA; confirms low-loss conduction during forward-biased fault conditions) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4730A | Same 4.7 V nominal, but ±5 % tolerance, 1 W Ptot, higher rdif (60 Ω), TO-92 plastic package | Limited to lower-power PCBs without extended copper; less robust under surge due to plastic encapsulation | Select when cost is primary and surge immunity is not required; avoid in automotive or industrial surge-prone environments |
| BZX55-C4V7 | Same 4.7 V, ±5 %, but 500 mW Ptot, 60 Ω rdif, DO-35 glass package (smaller, lower thermal mass) | Suitable only for signal-level biasing; derates rapidly above 70 °C ambient | Choose only for space-constrained low-current applications (<5 mA); not viable for power rail clamping |
Compared with 1N4730A and BZX55-C4V7, BZV85-C4V7,113 delivers 30 % higher power handling, 25 % lower dynamic impedance, and hermetic reliability - making it the preferred choice for industrial-grade shunt regulation where thermal margin and long-term stability are mandatory.

FAQ
What is the maximum continuous reverse current the BZV85-C4V7,113 can sustain at 25 °C ambient?
The device is rated for continuous operation at up to 500 mA forward current, but as a Zener diode, its continuous reverse (Zener) current is limited by power dissipation. At 25 °C ambient with 10 mm leads, Ptot = 1 W limits IZ to approximately 213 mA (1 W ÷ 4.7 V). Derating applies above 25 °C per the Rth(j-a) = 175 K/W curve.
Can BZV85-C4V7,113 be used in series or parallel configurations for higher voltage or current capability?
Series connection is feasible for higher voltage references but requires matched units to avoid unequal voltage sharing; parallel use is strongly discouraged due to negative thermal feedback and current hogging. For higher current, a series-pass transistor with BZV85-C4V7,113 as reference is recommended per Figure 12 in the datasheet.
How does the −2.0 to +0.7 mV/K temperature coefficient affect circuit performance across −40 °C to +125 °C?
Over this range, the Zener voltage shift is bounded by ±0.14 V (70 K × 2 mV/K), resulting in a worst-case VZ of 4.56–4.84 V. This 6 % total span remains within the ±5 % initial tolerance band, preserving regulation integrity without external compensation.
Is the SOD66 (DO-41) package RoHS-compliant and lead-free?
Yes - Nexperia confirms the BZV85-C4V7,113 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, with full compliance documentation available via Nexperia's product change notifications (PCN #PCN-2018-017).
