Product details
Overview
BZX84-C62,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 62 V nominal breakdown voltage at 2 mA, 250 mW total power dissipation, and 150 °C maximum junction temperature - used for precision voltage reference and overvoltage protection in low-power DC rails.
For engineers reviewing the BZX84-C62,215 datasheet, BZX84-C62,215 pinout, BZX84-C62,215 application, or BZX84-C62,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (450 Ω max), temperature coefficient (+0.05 mV/K), non-repetitive peak reverse current (0.3 A), and thermal resistance (330 K/W to solder point).
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage across a load by conducting reverse current when input exceeds its 62 V Zener threshold. It exhibits a positive temperature coefficient of +0.05 mV/K at IZ = 2 mA, indicating minimal drift over temperature.
Designed for surface-mount use on FR4 PCBs with standard SOT23 footprint, it supports pulse operation up to 40 W (100 μs, square wave) and continuous DC regulation up to 250 mW at Tamb ≤ 25 °C, with thermal resistance from junction to solder point at 330 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V nominal at IZ = 2 mA; min 58 V / max 66 V (±5 % tolerance) |
| Differential Resistance (rdif) | 450 Ω maximum at IZ = 2 mA; defines regulation stiffness under load variation |
| Reverse Current (IR) | 215 μA maximum at VR = 49.6 V; sets leakage-related power loss in standby |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB; limits continuous DC regulation capability |
| Junction Temperature (Tj) | −55 °C to +150 °C operating range; enables use in industrial ambient environments |
| Non-repetitive Peak Reverse Current (IZSM) | 0.3 A at tp = 100 μs; supports transient overvoltage clamping without failure |
| Thermal Resistance (Rth(j-sp)) | 330 K/W to cathode solder point; determines thermal rise under sustained power |
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 side of regulated rail; reverse-biased during regulation |
| 2 | Not Connected (n.c.) | Internal die bond wire stub; electrically isolated and must remain unconnected |
| 3 | Cathode (K) | Connected to higher-potential side; carries full Zener current during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMT packaging | SOT23 footprint enables high-density PCB layouts and automated assembly compatibility |
| Controlled Zener tolerance | ±5 % (C-series) provides predictable voltage clamping within cost-sensitive designs |
| Pulse power handling | 40 W non-repetitive peak reverse power supports ESD and surge suppression roles |
| Stable temperature behavior | +0.05 mV/K tempco at IZ = 2 mA minimizes drift in ambient temperature variations |
| Low leakage performance | 215 μA IR at VR = 49.6 V ensures minimal standby current draw in battery-powered systems |

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 | 62 V nominal, ±5 %, 200 mW Ptot, 600 Ω rdif max at IZ = 20 mA | Higher rdif and lower Ptot reduce regulation accuracy and thermal margin in continuous use | Select when legacy ON Semi BOM alignment is required and power dissipation remains below 150 mW |
| Vishay BZX84-C62-TP | 62 V nominal, ±5 %, 300 mW Ptot, 400 Ω rdif max at IZ = 5 mA | Higher Ptot and lower rdif improve regulation stability but require revised thermal layout | Prefer for higher-reliability industrial designs where 300 mW headroom and tighter rdif support longer lifetime |
Compared with BZX84-C62,215, MMBZ5262B offers lower power handling and higher impedance, while BZX84-C62-TP delivers improved thermal margin and regulation stiffness - making the latter suitable for extended-life deployments where 50 mW extra dissipation headroom matters.

FAQ
What is the Zener test current for BZX84-C62,215?
The specified Zener voltage of 62 V is measured at IZ = 2 mA, per Table 9 in the datasheet. This current level balances measurement repeatability and thermal self-heating effects, and is used for all parameter characterization including differential resistance and temperature coefficient.
Can BZX84-C62,215 be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients at low voltages but positive ones above ~5 V (here +0.05 mV/K), yet manufacturing spread in VZ causes uneven current sharing. Parallel connection risks thermal runaway and premature failure; use a single higher-rated device instead.
Is pin 2 internally connected or truly floating?
Pin 2 is explicitly marked "n.c." (not connected) in Table 2 and confirmed in the simplified outline graphic. It is an unused lead with no internal bond wire or die connection - must remain unconnected in PCB layout to avoid parasitic coupling or mechanical stress.
How does the ±5 % tolerance affect regulation accuracy in practice?
At 62 V nominal, ±5 % means actual VZ falls between 58 V and 66 V. In closed-loop regulation, this directly translates to ±4 V output error unless compensated via trimming or feedback calibration - acceptable for clamping but marginal for precision references.
