Product details
Overview
BZX884-C33,315 from Nexperia is a ±5% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 33 V nominal regulation at 5 mA, with 250 mW total power dissipation and 75 Ω typical differential resistance. It serves as a precision voltage reference or overvoltage clamp in low-power analog circuits, automotive sensor interfaces, and ESD protection networks.
For engineers reviewing the BZX884-C33,315 datasheet, BZX884-C33,315 pinout, BZX884-C33,315 application, or BZX884-C33,315 equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (500 K/W), reverse leakage (<100 nA at 23.1 V), junction temperature limit (150 °C), and AEC-Q101 qualification for automotive use.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its 33 V nominal Zener voltage is specified at IZ = 5 mA, with a temperature coefficient of +29.7 mV/K and differential resistance of 75 Ω (typical) at that test current.
The device uses silicon planar epitaxial construction in a leadless DFN1006-2 package, enabling high-frequency response (capacitance ≤45 pF at 1 MHz, VR = 0 V) and ultra-fast ESD clamping (non-repetitive peak reverse current = 0.9 A, tp = 100 µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 32.34 V to 34.66 V at IZ = 5 mA - defines regulation window for precision biasing or reference applications |
| Differential Resistance (rdiff) | 75 Ω (typical) at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Leakage (IR) | <100 nA at VR = 23.1 V - ensures minimal quiescent current in standby or battery-powered circuits |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables low-loss forward conduction during transient clamping |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC or pulsed power handling capability |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in extended industrial and automotive under-hood environments |
| Thermal Resistance (Rth(j-a)) | 500 K/W - quantifies self-heating under ambient conditions; requires thermal layout consideration for sustained loads |
Pinout & Package
SOD882 (DFN1006-2) is a leadless ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.5 mm, with exposed copper terminals on the bottom and a marking bar indicating the cathode side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output node; reverse-biased during Zener operation; carries clamping current during overvoltage events |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path; must be routed with low-inductance for ESD performance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics including engine control modules and body electronics requiring reliability under thermal cycling and vibration |
| Ultra-small SOD882 footprint | Enables placement in space-constrained PCB areas such as sensor modules and portable medical devices without sacrificing thermal or electrical performance |
| 75 Ω differential resistance at 5 mA | Provides tighter voltage regulation than standard ±5% Zeners with rdiff > 100 Ω, reducing output drift under load variation |
| 45 pF capacitance at 0 V | Supports high-frequency noise suppression and ESD protection up to ~350 MHz without signal integrity degradation |
| Non-repetitive peak reverse current: 0.9 A | Handles IEC 61000-4-2 Level 4 ESD transients (8 kV contact / 15 kV air) with single-event clamping capability |
Applications
| Automotive Sensor Biasing | Industrial Analog Signal Conditioning |

FAQ
What is the maximum reverse voltage this Zener can sustain before breakdown?
The BZX884-C33,315 has a nominal Zener voltage of 33 V, with guaranteed breakdown occurring between 32.34 V and 34.66 V at 5 mA test current. Below 32.34 V, reverse leakage remains below 100 nA; sustained operation above 34.66 V risks exceeding its 250 mW power limit and thermal derating curve.
Is this part suitable for ESD protection in USB 2.0 data lines?
No - the BZX884-C33,315 is rated for 33 V Zener voltage and 45 pF capacitance, making it unsuitable for 5 V USB 2.0 data lines where clamping voltage must be <6 V and capacitance <3 pF. It is intended for higher-voltage rails like 24 V or 33 V power domains, not high-speed signal lines.
How does the ±5% tolerance affect regulation accuracy in a 12-bit ADC reference circuit?
At 33 V nominal, ±5% tolerance means actual VZ ranges from 31.35 V to 34.65 V. When used as a reference for a 12-bit ADC with 3.3 V full-scale range, this introduces ≥±1 LSB error in gain calibration unless trimmed or compensated via software, limiting absolute accuracy to ~0.5% without post-calibration.
Can this Zener replace a BZX884-B33 in an existing design?
Yes, but with trade-offs: the BZX884-C33 has ±5% tolerance versus ±2% for the BZX884-B33, resulting in wider VZ spread (31.35–34.65 V vs. 32.34–33.66 V). Differential resistance is similar (~75 Ω), but temperature coefficient differs (+29.7 mV/K vs. +26.6 mV/K), affecting thermal drift in precision applications.
