Product details
Overview
BZT52-C62J from Nexperia is a ±5 % tolerance Zener voltage regulator 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 low-power voltage reference and overvoltage clamping in industrial sensor signal conditioning circuits.
For engineers reviewing the BZT52-C62J datasheet, BZT52-C62J pinout, BZT52-C62J application, or BZT52-C62J equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (210 K/W junction-to-solder-point), reverse current limit (140 μA at VR = 58 V), temperature coefficient (+0.05 mV/K), and SOD123 surface-mount compatibility with standard reflow footprints.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its 62 V nominal regulation point targets mid-range industrial supply rail monitoring and transient suppression where tighter tolerance than general-purpose Zeners is required but automotive qualification is not needed.
The device exhibits a positive temperature coefficient of +0.05 mV/K at IZ = 5 mA, indicating minimal drift over temperature, and supports non-repetitive peak reverse power dissipation up to 35 W for 100 μs pulses-critical for ESD and surge protection in low-energy interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 58 V to 66 V at IZ = 2 mA - defines precise clamping threshold for 62 V nominal rail protection |
| Differential Resistance rdif | 400 Ω max - ensures <100 mV output variation per 250 μA current change, critical for stable reference |
| Reverse Current IR | 140 μA max at VR = 58 V - limits standby leakage in battery-powered sensing nodes |
| Total Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Junction-to-Solder-Point Rth(j-sp) | 210 K/W - enables thermal design margin for 1 cm² cathode pad layout without forced cooling |
| Non-Repetitive Peak Power PZSM | 35 W for tp = 100 μs - supports single-event surge suppression per IEC 61000-4-2 Level 4 |

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 MMBZ5262B | Same 62 V nominal, ±5 % tolerance, but SOT-23 package (higher Rth(j-a) = 375 K/W) | Less suitable for high-ambient thermal environments due to inferior thermal path | Select when board space is constrained and thermal load is <100 mW |
| Vishay BZX84-C62 | 62 V nominal, ±5 %, but higher rdif = 500 Ω max and 175 μA IR at 58 V | Higher leakage and impedance reduce accuracy in precision reference designs | Select only for cost-sensitive, non-critical clamping where 10 % regulation error is acceptable |
Compared with MMBZ5262B and BZX84-C62, BZT52-C62J delivers superior thermal performance (210 K/W vs. ≥375 K/W) and tighter regulation stability (400 Ω vs. ≥500 Ω rdif), making it preferred for industrial-grade signal integrity and long-life embedded deployments.

FAQ
What is the maximum continuous reverse current the BZT52-C62J can handle?
The BZT52-C62J is rated for a maximum continuous forward current of 250 mA, but as a Zener diode operating in reverse breakdown, its steady-state reverse current is limited by power dissipation. At 62 V, sustained operation above 9.5 mA exceeds the 590 mW Ptot rating at 25 °C ambient, so derating is required above that current level.
Does the BZT52-C62J meet automotive AEC-Q200 requirements?
No. The BZT52-C62J is explicitly designated as non-automotive qualified in the datasheet revision history. It lacks AEC-Q200 stress testing and qualification; for automotive applications, Nexperia offers the -Q qualified variants (e.g., BZT52-C62J-Q), which undergo extended temperature cycling, humidity testing, and vibration validation.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a specified temperature coefficient of +0.05 mV/K at IZ = 5 mA, the BZT52-C62J exhibits approximately ±3.5 mV total drift across a 165 K temperature span-less than 0.006 % of nominal 62 V. This stability is confirmed in Fig. 7 of the datasheet for the C-series 62 V part.
Can the BZT52-C62J be used in parallel for higher power dissipation?
No. Zener diodes exhibit negative temperature coefficients below ~5 V and positive above ~5 V, but even within the same batch, minor VZ mismatches cause current hogging. Parallel operation is not recommended; instead, use a single higher-rated device or add external ballast resistors if thermal derating is insufficient.
