Product details
Overview
HPZR-C3V3-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 5.5 W total power dissipation at Tsp = 75 °C, with nominal working voltage 3.3 V (±5 % tolerance), forward voltage ≤ 1 V at 100 mA, and ESD rating of 30 kV per IEC 61000-4-2 (contact discharge). It serves as a precision low-current voltage reference and overvoltage clamp in automotive power rails.
For engineers reviewing the HPZR-C3V3-QX datasheet, HPZR-C3V3-QX pinout, HPZR-C3V3-QX application, or HPZR-C3V3-QX equivalent, this device is selected for stable 3.3 V regulation under transient load conditions, thermal-limited PCB layouts, AEC-Q101-compliant automotive subsystems, and high-ESD environments requiring robust reverse-bias clamping.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 3.10–3.50 V at IZ = 100 mA, differential resistance RZ ≤ 8.0 Ω, and reverse current IR ≤ 60 μA at VR = 1.0 V. Its thermal design relies on junction-to-solder-point resistance Rth(j-sp) = 18 K/W for effective heat transfer through the cathode tab.
The device supports non-repetitive peak power dissipation up to 800 W for tp ≤ 100 μs and withstands IFSM = 50 A (8.3 ms half-sine), enabling surge suppression in 12 V automotive circuits. It is qualified per AEC-Q101 and specified for operation from −55 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 3.10–3.50 V at IZ = 100 mA - defines regulated output voltage range under nominal bias |
| Total Power Dissipation (Ptot) | 5500 mW @ Tsp = 75 °C (zero lead length) - maximum continuous DC power handling at solder point temperature limit |
| Forward Voltage (VF) | ≤ 1.0 V at IF = 100 mA - ensures low conduction loss during forward-biased fault conditions |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - enables direct placement on exposed I/O lines without external ESD protection |
| Differential Resistance (RZ) | ≤ 8.0 Ω at IZ = 100 mA - determines regulation stiffness and output voltage variation under load current changes |
| Junction Temperature (Tj) | −55 °C to +175 °C - supports under-hood automotive deployment without derating in sealed enclosures |
| Package | CFP3 (SOD123W), 2.6 mm × 1.7 mm × 1.0 mm - low-profile SMD footprint compatible with automated reflow and wave soldering |
Pinout & Package
HPZR-C3V3-QX uses a 2-terminal CFP3 (SOD123W) surface-mount plastic package with cathode marked by a bar on the body. Thermal performance depends critically on the cathode pad (Pin 1) solder connection, which serves as the primary heat path to the PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main thermal and electrical return node; requires ≥1 cm² copper pad for rated 5.5 W dissipation |
| 2 | Anode (A) | Reference input terminal; connects to regulated rail or voltage source during reverse-bias operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per discrete semiconductor standard |
| High ESD immunity | 30 kV contact discharge rating eliminates need for upstream TVS in many infotainment and body control modules |
| Low-profile thermal package | CFP3 footprint delivers 5.5 W power handling in <1 mm height - enables compact layout in space-constrained ECUs |
| Tight voltage tolerance | ±5 % VZ ensures predictable clamping threshold across production lots without post-assembly calibration |
| Low dynamic impedance | RZ ≤ 8.0 Ω maintains stable regulation under fast load transients typical in microcontroller power domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3 | 300 mW Ptot, SOT23 package, RZ = 90 Ω, VZ tolerance ±5 % | Limited to low-power logic-level clamping; unsuitable for >100 mA load regulation or automotive under-hood use | Select only for cost-sensitive consumer PCBs where thermal margin exceeds 4× and AEC-Q101 is not required |
| MMSZ4677 | 500 mW Ptot, SOD123 package, RZ = 20 Ω, VZ = 3.3 V ±5 %, no AEC-Q101 qualification | Lower surge capability (IFSM = 10 A), no 30 kV ESD rating, unqualified for automotive temperature cycling | Acceptable for industrial control panels with controlled environment but not for automotive OEM production |
Compared with BZX84-C3V3 and MMSZ4677, HPZR-C3V3-QX provides 11× higher power handling, 10× lower dynamic impedance, and certified AEC-Q101 reliability-making it the sole choice for production automotive voltage regulation where thermal, surge, and qualification constraints coexist.

FAQ
What is the maximum continuous current HPZR-C3V3-QX can regulate at 75 °C solder point temperature?
At Tsp = 75 °C with zero lead length, HPZR-C3V3-QX supports up to 400 mA forward current (IF) and regulates 3.3 V with ≤5.5 W total dissipation. Its Zener regulation current IZ is typically operated between 5 mA and 200 mA to maintain VZ stability within ±5 % and RZ ≤ 8.0 Ω.
How does the CFP3 (SOD123W) package improve thermal performance versus standard SOD123?
The CFP3 variant features an extended cathode tab that increases copper contact area and reduces Rth(j-sp) to 18 K/W-40 % lower than standard SOD123. This allows 5.5 W dissipation at Tsp = 75 °C versus ~1.5 W for conventional SOD123, verified via JEDEC JESD51-2 compliant thermal testing.
Is HPZR-C3V3-QX suitable for bidirectional ESD protection?
No-it is a unidirectional Zener diode optimized for reverse-bias regulation and clamping. Its forward voltage is ≤1.0 V at 100 mA, but it lacks symmetric breakdown characteristics. For bidirectional protection, a dedicated TVS array like PESD5V0S1BA must be used instead.
Does the 30 kV ESD rating apply to both anode and cathode terminals?
The 30 kV rating per IEC 61000-4-2 (contact discharge) applies specifically to the cathode terminal, as confirmed in Table 6 footnote [2]: "Soldering point of cathode tab." The anode exhibits lower ESD robustness and must not be used as the primary ESD strike point in system-level designs.
