Product details
Overview
BZX84-C62,235 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 62 V nominal breakdown voltage at 2 mA, 250 mW total power dissipation, and 150 °C maximum junction temperature - used for precision low-power voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the BZX84-C62,235 datasheet, BZX84-C62,235 pinout, BZX84-C62,235 application, or BZX84-C62,235 equivalent, key selection considerations include its 62 V Zener voltage tolerance (±5 %), differential resistance of 450 Ω at 2 mA, reverse current ≤0.1 μA at 49.6 V, and thermal resistance of 500 K/W in free air - critical for stable biasing and clamping in space-constrained DC-DC converters.
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 temperature conditions. Its 62 V nominal Zener voltage is specified at IZ = 2 mA with a temperature coefficient of +0.05 mV/K, indicating minimal drift over temperature.
The device features non-repetitive peak reverse power dissipation up to 40 W for 100 μs pulses, enabling transient overvoltage suppression. Its 450 Ω differential resistance at 2 mA defines regulation stiffness, while 0.1 μA reverse leakage at VR = 49.6 V ensures low quiescent current in standby operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 58.0 V to 66.0 V at IZ = 2 mA - defines usable regulation range for 62 V nominal reference |
| Differential Resistance (rdif) | 450 Ω max at IZ = 2 mA - determines output impedance and regulation error under load variation |
| Reverse Current (IR) | ≤0.1 μA at VR = 49.6 V - ensures minimal leakage in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets continuous DC power limit for thermal design |
| Junction Temperature (Tj) | −65 °C to +150 °C - enables operation in industrial ambient environments without derating below −40 °C |
| Thermal Resistance (Rth(j-a)) | 500 K/W in free air - informs board-level thermal management requirements for sustained 250 mW operation |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - supports surge clamping in ESD or inductive kickback protection |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; standard footprint per Nexperia's reflow soldering guidelines (Fig. 12). Device mounted on FR4 PCB with single-sided 70 µm copper, tin-plated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node in reverse-bias configuration; carries forward current during fault conditions |
| 2 | Not Connected (n.c.) | Internally unconnected lead - must remain floating; no PCB trace or pad required |
| 3 | Cathode (K) | Connected to regulated voltage node; serves as reference output in shunt regulator topologies |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., non-critical biasing |
| 250 mW total power dissipation | Supports continuous operation in low-current shunt regulators without heatsinking on standard FR4 PCB |
| 40 W non-repetitive peak reverse power | Provides robust transient suppression for 100 μs surges in power rail protection circuits |
| 150 °C maximum junction temperature | Allows reliable operation in enclosed industrial enclosures with ambient temperatures up to +85 °C |
| 450 Ω differential resistance at 2 mA | Delivers predictable regulation error under load changes in feedback divider networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5262BS | 62 V nominal, ±5 %, SOT23, 200 mW Ptot, 500 Ω rdif at 20 mA | Higher test current (20 mA vs. 2 mA) yields lower apparent rdif but higher operating power | Select when higher Zener current capability is needed and thermal budget allows 200 mW at elevated IZ |
| Vishay BZX84-C62-7-F | 62 V nominal, ±5 %, SOT23, 300 mW Ptot, 450 Ω rdif at 2 mA, AEC-Q200 qualified | Higher power rating and automotive qualification enable use in harsher environments | Select for automotive-grade designs requiring extended temperature validation and 300 mW headroom |
Compared with MMBZ5262BS, BZX84-C62,235 offers tighter thermal design control at low current (2 mA), while Vishay's BZX84-C62-7-F provides higher power margin and automotive qualification - making the Nexperia part optimal for cost-sensitive industrial power supplies where 250 mW and 2 mA operation are sufficient.

FAQ
What is the Zener test current for BZX84-C62,235?
The BZX84-C62,235 is characterized at IZ = 2 mA for Zener voltage (VZ = 58.0 V to 66.0 V), differential resistance (rdif ≤ 450 Ω), and temperature coefficient (SZ = +0.05 mV/K). This low test current enables stable operation in ultra-low-power bias networks without significant self-heating.
Can BZX84-C62,235 be used in place of a 6.2 V Zener diode?
No - BZX84-C62,235 is a 62 V Zener diode, not 6.2 V. The "62" in the part number denotes nominal breakdown voltage in volts. Substituting it for a 6.2 V device would result in catastrophic failure due to excessive reverse voltage across downstream circuitry; always verify voltage rating before replacement.
Is Pin 2 electrically functional in BZX84-C62,235?
No - Pin 2 is internally not connected (n.c.) and must remain unconnected on the PCB. Routing a trace or applying solder to Pin 2 may cause mechanical stress or unintended parasitic coupling; Nexperia's package outline (Fig. 11) confirms this lead is a dummy terminal for mechanical stability only.
How does the ±5 % tolerance affect regulation accuracy in practice?
The ±5 % tolerance means actual VZ falls between 58.0 V and 66.0 V at 2 mA. In feedback applications, this translates to potential output voltage error proportional to the resistor divider ratio - e.g., a 10:1 divider yields ±0.5 V uncertainty at the regulated rail, requiring system-level calibration or margining if tighter accuracy is needed.
