Product details

Overview

BZX84-C6V2,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 6.2 V nominal breakdown voltage at 5 mA, 150 Ω typical differential resistance, and 250 mW total power dissipation - used for precision low-power voltage reference and overvoltage protection in power supply feedback loops.

For engineers reviewing the BZX84-C6V2,215 datasheet, BZX84-C6V2,215 pinout, BZX84-C6V2,215 application, or BZX84-C6V2,215 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (330 K/W junction-to-solder-point), non-repetitive peak reverse power (40 W), and cathode/anode terminal configuration in compact SMT layout.

Technical Context

This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage across load variations by conducting reverse current above its specified Zener breakdown threshold of 5.80–6.60 V at I_Z = 5 mA. Its temperature coefficient of +0.4 to +3.7 mV/K enables predictable drift behavior in ambient ranges from –55 °C to +150 °C.

Designed for surface-mount integration on FR4 PCBs with single-sided 70 µm copper, it delivers 10 µA maximum reverse leakage at VR = 4.96 V and supports transient suppression via 40 W non-repetitive peak reverse power handling under 100 µs square-wave pulses.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	5.80–6.60 V at I_Z = 5 mA; defines regulation window for feedback sensing in 5 V–6.3 V systems
Differential Resistance r_dif	150 Ω max at I_Z = 5 mA; determines output impedance and load regulation sensitivity
Total Power Dissipation P_tot	250 mW at T_amb ≤ 25 °C; sets continuous DC power limit on standard FR4 PCB
Forward Voltage V_F	≤ 0.9 V at I_F = 10 mA; ensures low conduction loss when used in series polarity configurations
Non-repetitive Peak Power	40 W at t_p = 100 µs; enables transient surge clamping without thermal runaway
Junction-to-Solder-Point R_th(j-sp)	330 K/W; quantifies thermal path efficiency from die to PCB copper for reliability modeling
Reverse Leakage I_R	≤ 3 µA at V_R = 4.96 V; ensures minimal quiescent current in standby regulation circuits

Pinout & Package

Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package with 1.9 mm × 1.1 mm footprint and 1.4 mm height; optimized for reflow and wave soldering per IPC-7351B.

Pin/Terminal	Circuit Role	Design Meaning
1	Anode (A)	Connected to lower-potential node in shunt regulation; reverse-biased during Zener operation
2	Not Connected (n.c.)	Internal die pad with no electrical connection; must remain unconnected in PCB layout
3	Cathode (K)	Connected to higher-potential node; carries reverse current during regulation; primary thermal path to PCB

Key Features

Feature	Design Value
±5 % Zener voltage tolerance	Enables cost-effective voltage reference where tight regulation is secondary to robustness and manufacturability
250 mW power rating	Supports continuous regulation in low-current analog rails (<10 mA) without heatsinking
330 K/W junction-to-solder-point thermal resistance	Allows direct thermal coupling to PCB copper for reliable operation up to 125 °C ambient
40 W non-repetitive peak power capability	Provides transient overvoltage immunity in DC-DC converter feedback paths and sensor interfaces
SOT23 footprint compatibility	Ensures drop-in replacement in legacy designs using industry-standard 0.95 mm pitch land pattern

Applications

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 MMBZ5234BS	6.2 V nominal, ±5 %, 200 mW P_tot, 170 Ω r_dif, SOT-23 package	Lower power rating reduces surge margin; higher r_dif degrades load regulation	Select when board space matches but thermal derating below 100 °C ambient is acceptable
Vishay BZX84-C6V2-7-F	6.2 V nominal, ±5 %, 300 mW P_tot, 150 Ω r_dif, same SOT23 footprint	Higher power rating improves long-term reliability under sustained 150 °C junction conditions	Prefer for high-temperature industrial environments where 250 mW margin is insufficient

Compared with BZX84-C6V2,215, MMBZ5234BS trades 50 mW power headroom for broader distributor availability, while BZX84-C6V2-7-F extends thermal safety margin without footprint change - both retain identical voltage tolerance and pinout for drop-in evaluation.

FAQ

What is the maximum continuous reverse current this diode can sustain at 25 °C ambient?

The BZX84-C6V2,215 sustains up to 40 mA continuous reverse current at 25 °C ambient when mounted on an FR4 PCB with standard footprint, derived from its 250 mW power rating and 6.2 V Zener voltage (I_Z = P_tot/V_Z). Derating applies above 25 °C per the 500 K/W junction-to-ambient thermal resistance.

Can this part replace a BZX84-B6V2 in an existing design?

Yes, but with trade-offs: BZX84-C6V2,215 has wider ±5 % tolerance (vs. ±2 % for BZX84-B6V2), resulting in a 5.80–6.60 V regulation band instead of 6.08–6.32 V. This may affect loop stability in tightly regulated feedback networks, though it remains suitable for clamping and coarse reference use.

How does the n.c. pin (Pin 2) impact PCB layout requirements?

Pin 2 is internally unconnected and must not be soldered to any net or copper pour. PCB layout must isolate this pad with minimum 0.15 mm clearance from adjacent traces or planes to prevent parasitic capacitance or unintended shorts during reflow, per Nexperia's SOT23 mechanical drawing.

Is this device qualified for automotive applications?

No - the BZX84-C6V2,215 is explicitly marked as non-automotive qualified per Nexperia's Rev. 7 datasheet. Automotive alternatives require the "-Q" suffix (e.g., BZX84-C6V2-Q) and undergo AEC-Q200 stress testing; this part lacks those qualifications and is intended for commercial/industrial use only.
