Product details
Overview
BZT52-C62X from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 62 V nominal Zener voltage at IZ = 2 mA, 400 Ω maximum differential resistance, and 590 mW total power dissipation at Tamb ≤ 25 °C; used for precision voltage reference and overvoltage clamping in low-power DC supply rails.
For engineers reviewing the BZT52-C62X datasheet, BZT52-C62X pinout, BZT52-C62X application, or BZT52-C62X equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-sp) = 55 K/W), reverse current at VR = 50 V (<140 μA), temperature coefficient (+0.05 mV/K), and SOD123 footprint compatibility with automated SMT assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its 62 V nominal regulation point targets mid-to-high-voltage biasing and protection functions where tighter tolerance than standard ±5 % parts is not required but robust thermal performance is critical.
The device exhibits low differential resistance (400 Ω max) and a positive temperature coefficient of +0.05 mV/K at IZ = 5 mA, enabling predictable drift behavior in temperature-sensitive references. Mounting on FR4 PCB with 1 cm² cathode pad yields Rth(j-sp) = 55 K/W, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 58.0 V to 66.0 V at IZ = 2 mA - defines stable regulation window for mid-range DC rail monitoring |
| Differential Resistance rdif | ≤ 400 Ω - ensures minimal output voltage shift under load current variation |
| Reverse Current IR | < 140 μA at VR = 50 V - guarantees low leakage in standby or high-impedance sensing nodes |
| Total Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Thermal Resistance Rth(j-sp) | 55 K/W - quantifies junction-to-solder-point heat transfer efficiency for thermal design margining |
| Junction Temperature Tj | 150 °C maximum - determines upper operating limit before irreversible degradation |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables use as low-loss series diode in dual-polarity clamp configurations |
Pinout & Package
SOD123 surface-mount plastic package: 2-terminal, flat lead, 2.80 mm × 1.70 mm body, 0.70 mm nominal lead pitch, cathode marked by band on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased during Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is secondary to thermal stability and footprint |

| Temperature coefficient: +0.05 mV/K | Provides predictable, low-drift voltage reference across -55 °C to +150 °C ambient range |
Applications
| Power Supply Voltage Reference | Overvoltage Clamp for Microcontroller I/O |
|---|---|
|
Use Scenario: Stabilizing feedback voltage in adjustable linear regulators or providing reference for ADC bias networks. IC Role / Device Role / Timing Role: Zener diode acts as passive two-terminal voltage reference source, replacing more complex IC references where 62 V level is required. Use Value: Delivers stable 62 V reference with <140 μA leakage at 50 V, minimizing quiescent current draw in battery-backed systems. |
Use Scenario: Protecting 3.3 V or 5 V microcontroller GPIO pins against accidental 60 V transients from relay coils or inductive loads. IC Role / Device Role / Timing Role: Functions as shunt overvoltage protector-conducts only when input exceeds 62 V, diverting surge energy to ground. Use Value: Limits clamped voltage to ≤66 V with 400 Ω dynamic impedance, preventing latch-up while surviving 100 μs/35 W surges per IEC 61000-4-5. |
| DC Rail Monitoring Threshold | High-Voltage Bias Generator |
|
Use Scenario: Triggering fault detection in industrial 48 V or 60 V DC distribution systems when voltage exceeds safe operating limits. IC Role / Device Role / Timing Role: Serves as threshold element in comparator input network, defining trip point for undervoltage/overvoltage alarms.

Use Scenario: Generating stable bias voltage for high-side gate drivers or op-amp input stages in motor control inverters. IC Role / Device Role / Timing Role: Supplies regulated 62 V auxiliary supply derived from main bus, decoupled via series resistor and local capacitor. Use Value: Maintains ≤400 Ω output impedance under 1 mA load, ensuring minimal droop during gate charge pulses in half-bridge drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-B62 | ±2 % tolerance (59.9–64.1 V), 150 Ω max rdif, same SOD123 package | Higher precision for feedback loops requiring tighter regulation; higher cost | Select when VZ stability over temperature and load is prioritized over cost |
| 1N4742A | 1 W rating, DO-41 through-hole package, 62 V ±5 %, 15 Ω rdif | Higher power handling but incompatible with SMT assembly; larger board area | Choose only for legacy through-hole designs or where >590 mW continuous dissipation is mandatory |
Compared with BZT52-C62X, BZT52-B62 offers tighter tolerance and lower dynamic impedance for precision references, while 1N4742A provides higher power capacity at the expense of SMT compatibility and modern thermal performance.

FAQ
What is the maximum continuous power dissipation for BZT52-C62X at 70 °C ambient?
At Tamb = 70 °C, derating applies: Ptot = 590 mW − [(70 − 25) × (590 mW / 125 K)] = 421 mW. This assumes standard FR4 mounting with 1 cm² cathode pad; exceeding this risks junction temperature exceeding 150 °C.
Can BZT52-C62X be used in parallel for higher current capability?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but BZT52-C62X has +0.05 mV/K, causing thermal runaway if paralleled without individual ballast resistors. Use a single device sized for the full load or select higher-power alternatives.
Is BZT52-C62X automotive qualified?
No-this part is non-automotive qualified per Nexperia's revision history (v.2, Oct 2025). For automotive applications, consult Nexperia's -Q qualified equivalents such as BZT52-C62-Q, which undergo AEC-Q101 stress testing and PPAP documentation.
What is the typical reverse recovery time for BZT52-C62X?
Reverse recovery time is not characterized or specified for Zener diodes in this series, as they operate in steady-state reverse breakdown-not switching mode. The device is not intended for高频 switching applications; use fast-recovery diodes like PMEG series for such roles.
