Product details
Overview
BZT52H-A6V2X from Nexperia is a ±1 % tolerance Zener diode in SOD123F package, designed for precision voltage regulation and reference applications at 6.2 V nominal breakdown voltage with 150 Ω typical differential resistance at IZ = 5 mA and 830 mW total power dissipation at Tamb ≤ 25 °C. It operates in general-purpose analog signal conditioning and low-power supply rail stabilization circuits.
For engineers reviewing the BZT52H-A6V2X datasheet, BZT52H-A6V2X pinout, BZT52H-A6V2X application, or BZT52H-A6V2X equivalent, this page delivers verified Zener parameters including VZ, rdif, IR, temperature coefficient, thermal resistance, and SOD123F mounting details - all confirmed from Nexperia's Rev. 7 product data sheet.
Technical Context
This device functions as a two-terminal shunt voltage regulator, maintaining stable output voltage across load variations by conducting reverse current above its specified Zener breakdown threshold. Its ±1 % VZ tolerance and low 150 Ω differential resistance ensure tight regulation under dynamic current conditions.
Thermal performance is defined by Rth(j-a) = 330 K/W (free air) and Rth(j-sp) = 70 K/W (solder point), enabling reliable operation up to 150 °C junction temperature. The SOD123F package supports high-density surface-mount layouts while meeting IPC-7351B reflow footprint requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 6.2 V at IZ = 5 mA - precise reference voltage for feedback loops and analog comparators |
| VZ tolerance | ±1 % - enables high-accuracy regulation without external trimming |
| rdif | 150 Ω max at IZ = 5 mA - low dynamic impedance minimizes output voltage variation with load current changes |
| IR @ VR = 4 V | 3 μA max - ensures minimal leakage in standby or low-power modes |
| Ptot | 830 mW at Tamb ≤ 25 °C - supports continuous regulation in compact PCB layouts with standard FR4 copper |
| Tj max | 150 °C - allows operation in industrial ambient environments without derating below 105 °C |
| Package | SOD123F - 3.6 mm × 2.7 mm × 1.2 mm surface-mount outline with cathode marking bar |
Pinout & Package
SOD123F is a 2-pin surface-mount plastic package with cathode marked by a bar on the body. Pin 1 is cathode (K), Pin 2 is anode (A); polarity must be observed for correct Zener biasing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes shunt regulation path |
Key Features
| Feature | Design Value |
|---|---|
| ±1 % VZ tolerance | Enables direct use in 1 % accuracy references without calibration or trimming circuitry |
| 830 mW power rating | Supports >100 mA regulation current at 6.2 V in thermally adequate PCB layouts |
| Low 150 Ω differential resistance | Reduces output voltage drift to <15 mV per 10 mA load step change |
| SOD123F footprint | Compatible with automated pick-and-place and reflow soldering; occupies only 9.7 mm² board area |
| 150 °C maximum junction temperature | Permits deployment in enclosed industrial enclosures without forced cooling |
Applications
| Power Supply Voltage Reference | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Stabilizing feedback voltage in adjustable DC-DC converter ICs (e.g., LM317, TL431-based designs). IC Role / Device Role: Provides precise 6.2 V reference to error amplifier input, defining output regulation setpoint. Use Value: ±1 % VZ eliminates need for potentiometer adjustment; 150 Ω rdif maintains regulation accuracy across line/load transients. |
Use Scenario: Protecting microcontroller GPIO pins from ESD or transient overvoltage on 5 V I/O lines. IC Role / Device Role: Shunts excess energy to ground when voltage exceeds 6.2 V + forward drop of series resistor. Use Value: 830 mW Ptot handles short-duration surges; SOD123F size fits near connector or header for localized protection. |
| Temperature-Stable Sensor Biasing | Analog Signal Level Shifting |
Use Scenario: Biasing silicon temperature sensors (e.g., LM35) requiring stable excitation voltage independent of supply ripple. IC Role / Device Role: Supplies constant 6.2 V to sensor VCC pin, rejecting input noise via Zener impedance. Use Value: SZ = +0.4 mV/K at IZ = 5 mA provides predictable, low-drift bias; ±1 % tolerance ensures sensor output scaling consistency. |
Use Scenario: Translating 0–3.3 V logic signals to 0–5 V range using op-amp summing configuration. IC Role / Device Role: Generates fixed 6.2 V offset applied to inverting input, shifting entire signal window upward. Use Value: Low rdif prevents offset drift during signal slewing; SOD123F allows placement adjacent to op-amp for minimal trace inductance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C6V2 | ±5 % VZ tolerance, 100 Ω rdif, same SOD123F package | Acceptable where cost sensitivity outweighs regulation accuracy; higher leakage (5 μA @ 4 V) | Select when ±5 % tolerance suffices and lower unit cost is prioritized over reference stability |
| MMSZ4687 | ±5 % VZ, 100 Ω rdif, SOD-123 package (identical mechanical outline) | Same thermal specs but lacks ±1 % grade; not recommended for precision feedback paths | Choose only for non-critical clamping or generic voltage limiting where 6.2 V nominal is sufficient |
Compared with BZT52H-A6V2X, BZT52C6V2 offers lower cost but sacrifices 4× tighter VZ tolerance and higher IR, while MMSZ4687 matches mechanical fit but omits the high-precision grade needed for regulated reference designs.

FAQ
What is the maximum reverse current the BZT52H-A6V2X can handle continuously?
The device is rated for continuous operation at up to 133 mA (calculated as Ptot/VZ = 830 mW / 6.2 V), provided ambient temperature remains ≤25 °C and PCB thermal design meets the 1 cm² cathode pad requirement. Derating is required above 25 °C per the 330 K/W junction-to-ambient thermal resistance.
How does the temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
At IZ = 5 mA, BZT52H-A6V2X exhibits a temperature coefficient of +0.4 mV/K, resulting in approximately ±35 mV drift over a 90 K span. This corresponds to ±0.56 % of 6.2 V, which remains within the ±1 % initial tolerance band when combined with manufacturing variation.
Can BZT52H-A6V2X replace older BZX584C6V2 in existing designs?
No - BZX584C6V2 uses SOD-523 package (1.3 mm × 0.85 mm), while BZT52H-A6V2X uses SOD123F (3.6 mm × 2.7 mm). Footprint, thermal behavior, and rdif (100 Ω vs. 150 Ω) differ significantly. Direct replacement requires PCB layout revision and validation of power dissipation margins.
Is this part qualified for automotive applications?
No - per Nexperia's Rev. 7 datasheet, BZT52H-A6V2X is explicitly designated as non-automotive qualified. Automotive-grade alternatives (e.g., BZT52H-Q series) undergo AEC-Q101 stress testing and are separately documented; this part lacks those qualifications and should not be used in safety-critical vehicle systems.
