Product details
Overview
BZX84W-C62F from Nexperia is a ±5 % tolerance Zener voltage regulator diode with nominal 62 V regulation, 150 Ω differential resistance at 5 mA, and 64.4 mV/K temperature coefficient, housed in an SOT323 (SC-70) package for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the BZX84W-C62F datasheet, BZX84W-C62F pinout, BZX84W-C62F application, or BZX84W-C62F equivalent, this page delivers verified Zener parameters, terminal mapping, thermal derating guidance, and validated alternatives for stable 62 V clamping in compact DC-DC and LDO designs.
Technical Context
This Zener operates in reverse breakdown with a specified 62 V nominal working voltage (58.0 V min / 66.0 V max), delivering regulated reference voltage under controlled current conditions. Its 150 Ω differential resistance ensures predictable voltage deviation across load variations at IZ = 5 mA.
The device exhibits a +64.4 mV/K temperature coefficient, indicating positive drift with junction temperature - critical for thermal stability analysis in high-ambient environments. It supports non-repetitive peak reverse power dissipation up to 40 W for surge suppression when pulse duration ≤ 100 µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 62 V (min 58.0 V, max 66.0 V at IZ = 2 mA); defines primary regulation point for feedback networks |
| Tolerance | ±5 % ('C' grade); sets absolute accuracy band for voltage reference applications |
| Differential Resistance | 150 Ω at IZ = 2 mA; determines output impedance and load regulation sensitivity |
| Temperature Coefficient | +64.4 mV/K at IZ = 2 mA; quantifies voltage drift per degree Celsius rise in Tj |
| Total Power Dissipation | 275 mW at Tamb = 25 °C on FR4 PCB; sets continuous DC power limit under standard mounting |
| Reverse Current (IR) | 50 nA at VR = 43.4 V (0.7 × VZnom); specifies leakage level below regulation threshold |
| Junction-to-Ambient Thermal Resistance | 455 K/W (FR4, single-sided copper); governs thermal derating above 25 °C ambient |
Pinout & Package
SOT323 (SC-70) leadless surface-mount plastic package with 3 terminals; footprint dimensions per Figure 9 (reflow) and Figure 10 (wave soldering); compatible with standard 0.65 mm pitch pick-and-place equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in Zener configuration |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or thermal pad connection |
| 3 | Cathode (K) | Reverse-biased terminal; connects to higher-potential node for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Wide voltage range coverage | 62 V nominal within 2.4 V–75 V E24 series - enables single-family sourcing across diverse supply rails |
| Low capacitance | 0.3 pF at 1 MHz, VR = 0 V - minimizes signal coupling in high-frequency regulation paths |
| High surge capability | 40 W non-repetitive peak reverse power (tp ≤ 100 µs) - supports transient overvoltage clamping |
| Stable temperature behavior | +64.4 mV/K coefficient optimized for mid-voltage Zeners - enables predictable thermal compensation |
| Standardized marking | "U7%" code per Table 4 - allows rapid visual identification of 62 V ±5 % variant on PCB |
Applications
| Power Supply Feedback Reference | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck-boost converters using optocoupler-coupled feedback. IC Role / Device Role / Timing Role: Zener diode provides precise 62 V reference to TL431 or shunt regulator input, setting secondary-side error threshold. Use Value: Tight ±5 % tolerance and low 150 Ω dynamic resistance ensure <±1.5 % output voltage variation across line/load/temperature. |
Use Scenario: Protecting downstream 60 V-rated MOSFET gates or ADC inputs from transient surges in industrial 48 V bus systems. IC Role / Device Role / Timing Role: Clamps voltage spikes exceeding 62 V by conducting reverse current into ground or rail. Use Value: 40 W non-repetitive surge rating absorbs 100 µs transients without degradation, preserving system reliability. |
| Low-Power Voltage Reference | Signal-Level Voltage Limiting |
Use Scenario: Generating stable bias points for analog front-end circuits in battery-powered sensors operating from 60–70 V sources. IC Role / Device Role / Timing Role: Provides low-current (≤5 mA), temperature-compensated reference for op-amp offset trimming or DAC reference scaling. Use Value: +64.4 mV/K coefficient enables predictable drift modeling; 50 nA leakage prevents loading of high-impedance nodes. |
Use Scenario: Preventing signal overshoot in RS-485 receivers or CAN transceivers connected to long cables exposed to ESD or inductive kick. IC Role / Device Role / Timing Role: Limits differential input voltage to safe levels before reaching receiver input stage. Use Value: 0.3 pF capacitance avoids signal integrity degradation at >10 MHz edge rates while clamping to 62 V. |
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 MMBZ5262B | 62 V ±5 %, 170 Ω rdif at 20 mA, −2 mV/K tempco, SOT-23 package | Higher test current (20 mA vs 2 mA) yields different rdif and tempco behavior; larger SOT-23 footprint | Select when higher test-current consistency is required and board space permits larger package |
| Vishay BZX84-C62 | 62 V ±5 %, 150 Ω rdif at 5 mA, +64 mV/K tempco, identical SOT323 package | No functional difference in regulation performance; minor process-level leakage and thermal resistance variance | Drop-in replacement with identical electrical and mechanical specs - suitable for second-source qualification |
Compared with BZX84W-C62F, MMBZ5262B requires revalidation of thermal and dynamic response due to differing test conditions and package size, while BZX84-C62 offers identical specification compliance and footprint compatibility for seamless dual-sourcing.

FAQ
What is the maximum continuous reverse current for BZX84W-C62F at 25 °C?
The device has no defined maximum continuous reverse current; instead, its limiting factor is total power dissipation of 275 mW at 25 °C ambient. At 62 V, this corresponds to a maximum average reverse current of approximately 4.4 mA (275 mW ÷ 62 V), assuming no additional thermal derating.
Can BZX84W-C62F be used in place of a 62 V Zener with ±2 % tolerance?
No - BZX84W-C62F is specifically the ±5 % tolerance variant ('C' suffix). The ±2 % version is BZX84W-B62, which has tighter voltage limits (60.8 V–63.2 V vs. 58.0 V–66.0 V) and different differential resistance (100 Ω vs. 150 Ω). Substitution requires verification of circuit margin against worst-case regulation error.
How does the 'n.c.' pin affect PCB layout and thermal design?
Pin 2 is internally not connected and must remain electrically isolated - no trace, thermal pad, or solder mask opening should contact it. Including it in copper pours or grounding it degrades reliability and may cause parametric shift. Layout must follow Nexperia's SOT323 footprint guidelines (Figure 9) to avoid solder bridging or tombstoning.
Is BZX84W-C62F qualified for automotive applications?
No - per Section 13 Revision History, this revision (Rev. 2, Jan 2023) explicitly states the product changed to non-automotive qualification. Automotive-grade equivalents (e.g., BZX84W-Q series) are separately qualified and marked; use of BZX84W-C62F in automotive systems voids warranty and violates safety compliance requirements.
