Product details
Overview
BZV90-C68,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, rated for 68 V nominal working voltage (±5%), 1.5 W total power dissipation, and 40 W non-repetitive peak reverse power at 100 μs. It delivers stable reference voltage in power supply feedback loops and overvoltage protection circuits for industrial DC-DC converters.
For engineers reviewing the BZV90-C68,115 datasheet, BZV90-C68,115 pinout, BZV90-C68,115 application, or BZV90-C68,115 equivalent, key selection criteria include its 68 V Zener voltage tolerance, low differential resistance (≤90 Ω), temperature coefficient of +0.25 mV/K, and SOT223 thermal performance with Rth j-a = 83.3 K/W on 2 cm² FR4 PCB.
Technical Context
This Zener diode operates in reverse breakdown to maintain precise DC voltage regulation under varying load and line conditions. Its design supports stable operation up to 150 °C junction temperature and handles transient surges up to 40 W for 100 μs with defined thermal derating per Fig.2.
It features a low capacitance of 35 pF at 0 V reverse bias and exhibits a positive temperature coefficient (+0.25 mV/K) near 68 V, enabling predictable drift compensation in temperature-sensitive references.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulator diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C68 | Same 68 V Zener voltage but SOT23 package; lower Ptot = 300 mW and higher rdif = 110 Ω | Limited to low-power biasing; unsuitable for >100 mA regulation or surge clamping | Select when board space is critical and thermal load ≤300 mW; avoid in power supply feedback or clamp roles |
| 1N4748A | Through-hole DO-41; same 68 V rating but Ptot = 1000 mW and Rth j-a ≈ 50 K/W on minimum pad | Requires larger PCB area and manual assembly; less suitable for automated SMT lines | Prefer for prototyping or legacy through-hole designs where reflow compatibility is not required |

FAQ
What is the maximum continuous reverse current the BZV90-C68,115 can sustain at 25 °C?
The BZV90-C68,115 does not specify a maximum continuous reverse current; instead, its safe operating limit is defined by power dissipation. At 25 °C ambient on a 2 cm² FR4 PCB, it sustains up to 22.1 mA continuous reverse current (68 V × 22.1 mA = 1.5 W), assuming no additional thermal overhead. Derating applies above 25 °C per Rth j-a = 83.3 K/W.
Can the BZV90-C68,115 be used in parallel for higher current handling?
No-parallel connection is not recommended due to mismatched Zener voltage tolerances (±5%) and temperature coefficients, which cause current hogging and thermal runaway. For higher current, use a single higher-power device or active regulation with a pass transistor, not multiple BZV90-C68,115 units.
Is the SOT223 package lead-free and RoHS compliant?
Yes-the BZV90-C68,115 is manufactured in accordance with Nexperia's standard RoHS-compliant processes. The SOT223 package uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level 3, with peak reflow temperature up to 260 °C.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a typical SZ of +0.25 mV/K, the BZV90-C68,115 exhibits ~42.5 mV total drift over 170 K span (−40 °C to +125 °C), or ±0.063% of 68 V. Combined with ±5% initial tolerance, worst-case regulation range remains within ±5.06%, sufficient for non-precision industrial power rails.
