Product details
Overview
BZX84-C6V2,235 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 6.2 V nominal breakdown at 5 mA, with 150 Ω max differential resistance and 3 µA max reverse current at 4 V. It delivers low-power regulation in space-constrained consumer and industrial power rails.
For engineers reviewing the BZX84-C6V2,235 datasheet, BZX84-C6V2,235 pinout, BZX84-C6V2,235 application, or BZX84-C6V2,235 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (330 K/W to solder point), non-repetitive surge capability (40 W), and SOT23 footprint compatibility with automated assembly.
Technical Context
This discrete Zener diode operates in reverse-biased breakdown mode to clamp or regulate voltage across load circuits. Its 6.2 V nominal Zener voltage is specified at IZ = 5 mA, with temperature coefficient of +0.4 mV/K and typical capacitance of 200 pF at 0 V.
The device supports pulsed operation up to 40 W for 100 µs (square wave), with junction-to-solder-point thermal resistance of 330 K/W and maximum junction temperature of 150 °C. It is not automotive-qualified and requires derating above 25 °C ambient per its 250 mW total power dissipation limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.80 V to 6.60 V at IZ = 5 mA - defines regulation band for precision reference or overvoltage clamping |
| Differential Resistance (rdif) | ≤150 Ω - determines output impedance and regulation stability under varying load current |
| Reverse Current (IR) | ≤3 µA at VR = 4 V - ensures minimal leakage in standby or high-impedance sensing paths |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets continuous DC power limit on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - enables transient surge suppression without failure |
| Thermal Resistance (Rth(j-sp)) | 330 K/W - quantifies junction-to-solder-point heat transfer efficiency for thermal design |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - relevant for polarity protection or series forward conduction use cases |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with standard footprint per Figure 12 (reflow) and Figure 13 (wave soldering); dimensions: 2.9 mm × 1.3 mm × 1.0 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node in reverse-bias configuration; carries forward current when used as rectifier |
| 2 | Not Connected (n.c.) | Internal die bond wire stub; electrically isolated and must remain unconnected in PCB layout |
| 3 | Cathode (K) | Connected to higher-potential node in reverse-bias configuration; primary terminal for Zener regulation path |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage reference where tight regulation is not critical (e.g., supply rail clamping) |
| 250 mW total power dissipation | Supports continuous regulation in low-current (<20 mA) applications without heatsinking |
| 40 W non-repetitive peak power | Provides robust ESD and transient immunity in I/O protection circuits |
| SOT23 package compatibility | Ensures placement compatibility with standard pick-and-place equipment and reflow profiles |
| 150 °C maximum junction temperature | Allows operation in extended-temperature industrial environments with appropriate board thermal design |
Applications
| Power Supply Rail Clamping | Reference Voltage Generation |
|---|---|
|
Use Scenario: Protecting microcontroller I/O pins from overvoltage transients on 5 V or 3.3 V supply lines. IC Role / Device Role / Timing Role: Zener diode connected cathode-to-rail, anode-to-ground to clamp voltage spikes above 6.2 V. Use Value: Limits voltage excursion to ≤6.6 V (max VZ) during 100 µs surges up to 40 W, preventing latch-up or damage. |

IC Role / Device Role / Timing Role: Reverse-biased Zener supplying regulated 6.2 V reference to high-impedance input nodes. Use Value: Delivers <3 µA leakage at 4 V reverse bias, minimizing quiescent current drain while maintaining ±5 % accuracy. |
| ESD Protection Network | Low-Cost Voltage Threshold Detection |
|
Use Scenario: Front-end protection for USB data lines or analog sensor inputs exposed to human-body-model (HBM) ESD events. IC Role / Device Role / Timing Role: Placed between signal line and ground to shunt fast transients before they reach sensitive IC inputs. Use Value: Responds within nanoseconds to 8 kV HBM pulses due to low junction capacitance (200 pF) and 40 W surge rating. |
Use Scenario: Detecting battery voltage drop below 6.2 V in portable medical devices to trigger low-battery warning. IC Role / Device Role / Timing Role: Used in simple comparator circuit where Zener voltage defines trip threshold. Use Value: Temperature coefficient of +0.4 mV/K ensures predictable threshold shift over –40 °C to +85 °C operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.

|---|---|---|---|
| ON Semiconductor MMBZ5234BLT1G | 6.2 V nominal, ±5 %, 200 mW Ptot, 170 Ω rdif, SOT23 package | Higher differential resistance reduces regulation precision under load variation | Select when legacy ON Semi sourcing or tighter stock availability is required |
| Vishay BZX84-C6V2-7-F | 6.2 V nominal, ±5 %, 300 mW Ptot, 150 Ω rdif, same SOT23 footprint | Higher power rating allows margin for higher continuous current or elevated ambient temperatures | Select when >250 mW continuous dissipation is needed or Vishay supply chain preference applies |
Compared with BZX84-C6V2,235, MMBZ5234BLT1G trades regulation precision for broader distributor availability, while BZX84-C6V2-7-F extends thermal headroom at identical voltage tolerance and package-enabling higher reliability in thermally constrained layouts.

FAQ
What is the maximum continuous reverse current this diode can handle at 6.2 V?
The BZX84-C6V2,235 is not rated for continuous reverse current at its Zener voltage. At VZ = 6.2 V, it operates in breakdown with a nominal test current of 5 mA. Continuous operation must stay within its 250 mW total power dissipation limit, corresponding to ~40 mA at 6.2 V - but actual safe current depends on ambient temperature and PCB thermal design per its 330 K/W junction-to-solder-point resistance.
Can this part replace a BZX84-B6V2 in an existing design?
Yes, but with trade-offs: BZX84-C6V2,235 has ±5 % tolerance (5.8–6.6 V) versus BZX84-B6V2's tighter ±2 % (6.08–6.32 V). If the application relies on precise 6.2 V regulation (e.g., feedback divider in switching regulator), the wider tolerance may cause output voltage drift. For clamping or coarse reference use, substitution is generally acceptable.
Is the n.c. pin (pin 2) safe to connect to ground or leave floating on the PCB?
Pin 2 is internally not connected and must remain unconnected on the PCB. Connecting it to ground or any net risks shorting internal die structures or compromising mechanical integrity during reflow. The official Nexperia SOT23 footprint (Figure 12) shows no pad for pin 2 - only pins 1 and 3 require copper land.
Does this Zener diode meet RoHS and REACH compliance?
Yes - BZX84-C6V2,235 is manufactured by Nexperia in accordance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its material declaration and substance compliance data are published in Nexperia's official product documentation and available via their website or authorized distributors.
