Product details
Overview
BZX84-C2V7,215 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for low-power precision voltage reference and overvoltage protection in space-constrained circuits. It delivers a nominal 2.7 V breakdown voltage at 5 mA, with 600 Ω max differential resistance, 20 μA reverse current at 1 V, and operates across –55 °C to +150 °C ambient range.
For engineers reviewing the BZX84-C2V7,215 datasheet, BZX84-C2V7,215 pinout, BZX84-C2V7,215 application, or BZX84-C2V7,215 equivalent, this device serves as a compact, thermally stable shunt regulator for power rail clamping, analog sensor biasing, and microcontroller reset circuitry where tight voltage tolerance and low leakage are critical.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage under varying load and temperature conditions. Its ±5 % tolerance (BZX84-C series) balances cost and performance for non-critical regulation tasks, while its 250 mW total power dissipation rating defines safe DC operating limits on standard FR4 PCBs.
The device exhibits a negative temperature coefficient of –3.5 mV/K at 5 mA, indicating voltage decreases with rising junction temperature - a key consideration for thermal drift compensation in precision analog designs. Its non-repetitive peak reverse power dissipation of 40 W supports transient surge suppression when used with appropriate series limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 2.50 V to 2.90 V at IZ = 5 mA - defines usable regulation window for 2.7 V nominal rail |
| Differential Resistance rdif | ≤600 Ω - determines output impedance and load regulation sensitivity |
| Reverse Current IR | ≤20 μA at VR = 1 V - ensures low standby power loss in bias networks |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power on standard PCB layout |
| Junction Temperature Range | –55 °C to +150 °C - enables operation in industrial and automotive-adjacent environments |
| Thermal Resistance Rth(j-a) | 500 K/W - quantifies self-heating rise per watt in free-air mounting |
| Non-repetitive Peak Power | 40 W for tp = 100 μs - supports short-duration ESD/surge clamping |
Pinout & Package

|---|---|---|---|
| MMBZ5223BS-7-F | 2.7 V ±5 %, 225 mW, SOT23, 600 Ω rdif, 20 μA IR at 1 V | Identical regulation spec but higher thermal resistance (625 K/W) | Select when legacy design uses Diodes Inc. footprint and sourcing requires dual-source flexibility |
| 1SMA5912BT3G | 2.7 V ±5 %, 500 mW, SMA package, 1000 Ω rdif, 50 μA IR at 1 V | Higher power rating but larger footprint and higher leakage | Select only if board layout allows SMA and system requires >250 mW continuous dissipation |
Compared with BZX84-C2V7,215, MMBZ5223BS-7-F offers identical electrical specs in same package but reduced thermal performance, while 1SMA5912BT3G trades size and leakage for higher power handling - making the Nexperia part optimal for space- and leakage-sensitive 2.7 V reference designs.

FAQ
What is the maximum continuous forward current for BZX84-C2V7,215?
The device is not rated for continuous forward conduction; its primary function is reverse-bias Zener operation. Absolute maximum forward current is 200 mA per limiting values table, but sustained forward bias exceeds design intent and risks degradation. Forward voltage is specified at 10 mA pulse (≤100 μs), yielding ≤0.9 V - intended only for test or transient conditions.
Can BZX84-C2V7,215 be used in place of a 2.7 V TL431 shunt regulator?
No - the BZX84-C2V7,215 is a passive two-terminal Zener diode with fixed 2.7 V breakdown and no adjustable reference or current-sink capability. The TL431 is an active three-terminal programmable shunt regulator offering adjustable output (2.5 V to 36 V), lower dynamic impedance (~0.2 Ω), and precise temperature stability. Use BZX84-C2V7,215 only where simplicity and cost outweigh regulation accuracy and adjustability.
How does the "215" suffix in BZX84-C2V7,215 affect specifications?
The "215" denotes the specific tape-and-reel packaging variant per Nexperia's ordering system: 3000 units per reel, 8 mm tape width, embossed carrier tape, and standard moisture sensitivity level (MSL 1). It does not alter electrical or thermal characteristics - all BZX84-C2V7 devices share identical Zener voltage, tolerance, power rating, and package dimensions regardless of suffix.
Is BZX84-C2V7,215 qualified for automotive applications?
No - per Revision 7 datasheet Section 13, this part is explicitly designated as non-automotive qualified. Nexperia removed automotive qualification in v.7 and directs users to dedicated -Q series parts (e.g., BZX84-C2V7-Q) for AEC-Q101-compliant designs. Using BZX84-C2V7,215 in automotive systems voids warranty and violates functional safety requirements for temperature cycling, humidity resistance, and long-term reliability validation.
