Product details
Overview
HPZR-C4V7-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision low-current regulation at nominal 4.7 V with ±5 % tolerance, 1.1 µA max reverse current at 1 mA test current, and 7.0 Ω differential resistance at 100 mA. It delivers 5.5 W total power dissipation at 75 °C solder point temperature and supports automotive-grade reliability per AEC-Q101.
For engineers reviewing the HPZR-C4V7-QX datasheet, HPZR-C4V7-QX pinout, HPZR-C4V7-QX application, or HPZR-C4V7-QX equivalent, this device is selected for stable reference generation in engine control units, battery management monitoring circuits, and ECU power rail clamping where compact SMD footprint, high ESD immunity (30 kV contact), and thermal robustness are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 4.40–5.00 V at IZ = 100 mA, maintaining tight regulation under varying load and temperature conditions. Its low differential resistance (7.0 Ω) ensures minimal output voltage drift across current changes, while its 1.1 µA reverse leakage at 1 mA enables low-quiescent-power biasing.
The device uses a planar silicon junction structure optimized for high surge capability (800 W non-repetitive peak power, tp ≤ 100 µs) and thermal stability up to 175 °C junction temperature. Its CFP3 package provides low thermal resistance to solder point (18 K/W), enabling efficient heat transfer from junction to PCB in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 4.40–5.00 V at IZ = 100 mA - defines precise regulation point for 4.7 V nominal reference applications |
| Total Power Dissipation | 5500 mW at Tsp = 75 °C (zero lead length) - enables sustained operation in thermally demanding under-hood environments |
| Differential Resistance | 7.0 Ω at IZ = 100 mA - ensures <1% output voltage variation over ±10 mA load change |
| Reverse Current | 1.1 µA max at VR = 1 V - supports ultra-low standby power in always-on vehicle subsystems |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact discharge) - protects against assembly-line and field electrostatic events without external TVS |
| Junction Temperature | −55 to +175 °C - qualified for full automotive ambient range including transmission and powertrain control modules |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing, including HTGB, HTRB, and temperature cycling |
Pinout & Package
HPZR-C4V7-QX is housed in a CFP3 (SOD123W) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, featuring flat leads and low-profile construction for automated reflow assembly on FR4 or ceramic PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked by bar on top surface; connects to regulated output node or voltage reference rail |
| 2 | Anode (A) | Positive terminal; ties to ground or lower-potential node to establish reverse-bias condition for Zener operation |
Key Features
| Feature | Design Value |
|---|---|

| Low Thermal Resistance | 18 K/W junction-to-solder-point - minimizes temperature rise during continuous 5.5 W operation on standard PCB copper pads |
| Automotive Qualification | AEC-Q101 compliant - meets stress test requirements for humidity, high temperature, and mechanical shock in safety-critical ECUs |
| Compact SMD Footprint | CFP3 (SOD123W) package - occupies only 4.4 mm² board area, enabling dense layout in ADAS sensor modules and body controllers |
| High ESD Immunity | 30 kV contact discharge rating - eliminates need for secondary ESD protection in CAN/LIN bus interface power rails |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C4V7 | 300 mW Ptot, SOT23 package, 100 Ω RZ, 5 µA IR at 1 V | Not rated for automotive; limited surge capability (100 W peak); unsuitable for under-hood thermal environments | Select only for cost-sensitive consumer electronics with <100 mW average power and no AEC-Q101 requirement. |

FAQ
What is the maximum continuous power dissipation for HPZR-C4V7-QX at 100 °C ambient?
At 100 °C ambient, HPZR-C4V7-QX derates to approximately 3.3 W based on its thermal resistance profile and the 175 °C maximum junction temperature limit. This value is derived from the Rth(j-a) curve in Figure 9 of the datasheet, assuming standard FR4 mounting with 1 cm² cathode pad.
Can HPZR-C4V7-QX replace a standard 1N4733A in an automotive design?
No-1N4733A is a through-hole 4.7 V Zener rated at 1 W with no AEC-Q101 qualification, 100 Ω RZ, and no ESD rating. HPZR-C4V7-QX provides 5.5× higher power, 14× lower RZ, 30 kV ESD immunity, and automotive qualification, making it functionally superior but requiring SMD layout adaptation.
What is the recommended PCB footprint for HPZR-C4V7-QX reflow soldering?
The official Nexperia footprint for CFP3 (SOD123W) specifies 1.1 mm × 1.1 mm solder lands with 1.2 mm × 1.4 mm solder resist opening and 0.1 mm stencil thickness. The full layout is documented in Figure 11 of the datasheet (sod123w_fr).
Does HPZR-C4V7-QX require heatsinking in typical automotive applications?
No external heatsink is required when mounted on a standard FR4 PCB with ≥1 cm² cathode copper pad. Its 18 K/W junction-to-solder-point thermal resistance allows full 5.5 W dissipation at Tsp = 75 °C, which corresponds to ~105 °C junction temperature under typical under-hood conditions.
