Product details
Overview
BZT52-C6V2J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 6.2 V nominal regulation at 5 mA, with 150 Ω max differential resistance and 3 μA max reverse current at 4.7 V, used for precision voltage reference and low-power rail clamping in sensor signal conditioning circuits.
For engineers reviewing the BZT52-C6V2J datasheet, BZT52-C6V2J pinout, BZT52-C6V2J application, or BZT52-C6V2J equivalent, this page delivers verified Zener voltage, thermal resistance, power dissipation limits, cathode/anode polarity marking, and SOD123 footprint compatibility - all critical for ESD-protected analog front-end design and PCB layout validation.
Technical Context
This device operates as a two-terminal voltage reference, conducting in reverse breakdown to maintain stable 6.2 V across its terminals when reverse-biased above its knee voltage. Its temperature coefficient of +0.4 to +3.7 mV/K (at IZ = 5 mA) enables predictable drift behavior in ambient-temperature-varying environments.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it exhibits Rth(j-a) = 350 K/W (free air) and Rth(j-sp) = 55 K/W (to cathode solder point), supporting thermal management in space-constrained consumer and industrial modules where heatsinking is impractical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.8 V to 6.6 V at IZ = 5 mA - defines tight regulation window for 6.2 V nominal rail stabilization |
| Differential Resistance rdif | 150 Ω max - ensures minimal output voltage shift under load current variation |
| Reverse Current IR | 3 μA max at VR = 4.7 V - guarantees low leakage in standby mode for battery-powered systems |
| Total Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 board |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - confirms low conduction loss when used in series protection configurations |
| Junction Temperature Tj | 150 °C max - establishes upper thermal limit for reliability in enclosed enclosures |
Pinout & Package
Package: SOD123 - surface-mount plastic package with 2 leads, 2.80 mm × 1.70 mm body, 0.70 mm lead pitch, cathode marked by a visible band on the component body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking band identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse bias applied between anode and cathode to activate Zener action |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective selection for non-critical reference applications without requiring tighter-tolerance (±2 %) B-series variants |
| Low differential resistance (150 Ω) | Maintains regulation stability under ±1 mA load changes - suitable for driving op-amp reference inputs |
| SOD123 footprint compatibility | Matches IPC-7351B standard land pattern (4.18 mm × 1.11 mm pad spacing), simplifying layout reuse across Zener families |
| Non-repetitive peak reverse power: 40 W | Withstands short-duration ESD transients (tp = 100 μs) per IEC 61000-4-2 Level 4 without degradation |
Applications
| Industrial Sensor Signal Conditioning | USB Port Overvoltage Clamp |
|---|---|
|
Use Scenario: Stabilizing reference voltage for 12-bit ADCs in temperature/humidity sensor nodes operating from 3.3 V rails. IC Role / Device Role / Timing Role: Zener diode provides fixed 6.2 V reference for internal DAC calibration and external comparator threshold setting. Use Value: 3 μA reverse leakage prevents measurable current draw from low-power microcontroller sleep modes. |
Use Scenario: Clamping D+ and D− lines against 12 V surge events in USB 2.0 host ports. IC Role / Device Role / Timing Role: Bidirectional transient suppressor configured in back-to-back arrangement with second Zener. Use Value: 40 W non-repetitive peak power rating absorbs 100 μs surges without parametric shift or failure. |
| IoT Node Battery Monitoring | Programmable Logic Supply Rail Clamp |
|
Use Scenario: Scaling Li-ion battery voltage (3.0–4.2 V) to fit 0–3.3 V ADC input range using resistor divider with Zener reference. IC Role / Device Role / Timing Role: Provides stable 6.2 V reference for ratio-metric divider scaling, independent of supply variation. Use Value: +0.4 to +3.7 mV/K tempco allows software compensation using onboard temperature sensor readings. |
Use Scenario: Protecting FPGA configuration I/O banks (1.8 V/2.5 V) from accidental 5 V misconnection during debug. IC Role / Device Role / Timing Role: Low-capacitance (200 pF) clamp shunts overvoltage before logic gate oxide breakdown occurs. Use Value: 200 pF capacitance at 0 V avoids signal integrity degradation on 10 MHz clock or data lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5234BLT1G | 6.2 V ±5 %, 500 mW Ptot, SOT-23 package, 200 Ω rdif | Higher thermal resistance (400 K/W) limits power handling on compact PCBs | Select when SOT-23 footprint is already standardized and 500 mW suffices |
| Vishay BZX84-C6V2 | 6.2 V ±5 %, 350 mW Ptot, SOT-23, 150 Ω rdif, 2 μA IR | Lower power rating restricts use to sub-10 mA regulation loads | Prefer for ultra-low-power designs where 350 mW ceiling is acceptable |
Compared with MMBZ5234BLT1G and BZX84-C6V2, BZT52-C6V2J offers superior thermal performance (55 K/W to solder point) and higher power margin (590 mW), making it optimal for sustained regulation in thermally dense layouts where SOD123's lower profile and better copper coupling matter.

FAQ
What is the maximum reverse voltage before breakdown for BZT52-C6V2J?
The specified Zener voltage is 5.8 V to 6.6 V at 5 mA test current; breakdown begins gradually below this range, with <3 μA leakage up to 4.7 V. Full regulation is only guaranteed within the 5.8–6.6 V window under defined test conditions.
Can BZT52-C6V2J be used in place of a BZT52-B6V2?
No - BZT52-B6V2 has ±2 % tolerance (5.88–6.12 V), while BZT52-C6V2J has ±5 % (5.8–6.6 V). The looser tolerance affects accuracy-critical references; substitution requires verification of system-level voltage margin and temperature drift impact.
Is the SOD123 package lead-free and RoHS compliant?
Yes - Nexperia confirms BZT52-C6V2J meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound per product change notice PCN-2023-012.
How does thermal resistance affect derating at elevated ambient temperatures?
At Tamb = 70 °C, Ptot must be reduced to ~380 mW using the 55 K/W junction-to-solder-point thermal resistance; full 590 mW is only valid at ≤25 °C ambient with specified 1 cm² cathode pad area.
