Product details
Overview
BZV85-C7V5,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 7.5 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation, and 60 W non-repetitive peak reverse power. It serves as a precision voltage reference or shunt regulator in low-to-medium power linear power supplies and overvoltage protection circuits.
For engineers reviewing the BZV85-C7V5,113 datasheet, BZV85-C7V5,113 pinout, BZV85-C7V5,113 application, or BZV85-C7V5,113 equivalent, this part is selected for stable DC voltage stabilization where thermal resistance to tie-point (110 K/W) and low differential resistance (3 Ω typical at test current) are critical for regulation accuracy under varying load conditions.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 7.0–7.9 V at 1 mA test current, exhibiting a positive temperature coefficient of +2.5 to +5.5 mV/K. Its junction-to-tie-point thermal resistance is 110 K/W (lead length 4 mm), enabling reliable operation up to 200 °C junction temperature when mounted on PCBs with 1 cm² copper per lead.
The device delivers 1.5 mA maximum reverse current at 5.0 V (VR), supports non-repetitive surge handling up to 60 W (100 µs square wave), and maintains ≤1 V forward voltage at 50 mA - confirming suitability for bidirectional clamping and dual-role (regulation + ESD suppression) implementations in cost-sensitive analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.0–7.9 V at IZ = 1 mA; defines precise shunt regulation point for 5 V–12 V rail stabilization |
| Differential Resistance (rdif) | 3 Ω max at IZ = 1 mA; ensures minimal output voltage drift under load variation |
| Total Power Dissipation (Ptot) | 1.3 W at Tamb = 25 °C, 10 mm lead length; sets continuous DC power handling limit |

| Reverse Current (IR) | ≤1500 µA at VR = 5.0 V; guarantees low leakage in standby or high-impedance bias networks |
| Forward Voltage (VF) | ≤1.0 V at IF = 50 mA; supports use as polarity-insensitive clamp or dual-function protection device |
| Thermal Resistance (Rth(j-t)) | 110 K/W (lead length 4 mm); determines required copper area for thermal management in PCB layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX85C7V5 | Same 7.5 V rating, but TO-204AA (DO-35) package; higher Rth(j-a) (500 K/W vs 175 K/W) | Limited to lower-power applications (<300 mW continuous); unsuitable for 1.3 W thermal loads | Select when legacy DO-35 footprint compatibility is required and power dissipation remains <0.3 W |
| MMBZ5231BS | SOT-23 surface-mount; 7.5 V, ±5 %, but Ptot = 300 mW and rdif = 30 Ω | Not suitable for high-current shunt regulation; intended for low-power signal clamping only | Select for space-constrained PCBs where 1.3 W operation is not needed and reflow compatibility is mandatory |
Compared with BZX85C7V5 and MMBZ5231BS, BZV85-C7V5,113 uniquely balances high power (1.3 W), low impedance (3 Ω), and through-hole reliability - making it optimal for industrial power supply references where thermal margin and mechanical robustness are prioritized over miniaturization.

FAQ
What is the maximum continuous reverse current this diode can handle at 7.5 V?
At nominal Zener voltage (7.0–7.9 V), BZV85-C7V5,113 supports up to 175 mA continuous reverse current when operated at its full 1.3 W power rating (P = V × I → I = 1.3 W / 7.5 V ≈ 173 mA). Derating is required above 25 °C ambient per its 110 K/W junction-to-tie-point thermal resistance.
Can this Zener diode be used in series or parallel configurations for higher voltage or current capability?
Series connection is viable for higher voltage references (e.g., two 7.5 V diodes yield ~15 V), but matching VZ and temperature coefficients is essential to avoid current hogging. Parallel operation is not recommended due to mismatched rdif, which causes uneven current sharing and potential thermal runaway.
How does the 110 K/W thermal resistance impact PCB layout requirements?
A 110 K/W Rth(j-t) means each watt of dissipated power raises the junction temperature by 110 K above the tie-point (4 mm from body). To maintain Tj ≤ 150 °C at 1.3 W, the tie-point must stay ≤ 15 °C above ambient - achieved via ≥1 cm² copper per lead, as specified in the datasheet.
Is the 7.5 V Zener voltage guaranteed across the full operating temperature range?
No - the 7.0–7.9 V specification applies at Tj = 25 °C. Over −65 °C to +200 °C, VZ shifts predictably per its +2.5 to +5.5 mV/K temperature coefficient. At 125 °C, VZ increases by ~0.3–0.5 V, resulting in a practical range of ~7.3–8.4 V in high-temp applications.
