Product details
Overview
HPZR-C63-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 63 V (±5 % tolerance), 30 kV ESD rating per IEC 61000-4-2 (contact), and AEC-Q101 qualification for automotive use.
For engineers reviewing the HPZR-C63-QX datasheet, HPZR-C63-QX pinout, HPZR-C63-QX application, or HPZR-C63-QX equivalent, this device serves as a robust, low-profile SMD voltage reference and overvoltage clamp in automotive power rails, battery management systems, and industrial sensor supply regulation where stable 63 V regulation and high surge immunity are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 63 V reference across its terminals under regulated current conditions (IZ = 20 mA). Its differential resistance is 54 Ω, ensuring tight voltage control under load variation. The device exhibits low leakage - maximum reverse current of 0.1 μA at VR = 60 V - critical for precision biasing.
Thermal design is enabled by low Rth(j-sp) = 18 K/W (to solder point) and Rth(j-a) = 70 K/W (on ceramic PCB), supporting high ambient operation up to +175 °C junction temperature. Non-repetitive peak power handling reaches 800 W for ≤100 µs pulses, enabling transient suppression in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 60.0 V to 66.3 V at IZ = 20 mA - defines precise clamping threshold for 63 V nominal rail protection |
| Total Power Dissipation (Ptot) | 5500 mW @ Tsp = 75 °C (zero lead length) - enables sustained thermal performance without heatsink in compact layouts |
| Differential Resistance (RZ) | 54 Ω at IZ = 20 mA - ensures < ±0.5 V output shift per ±10 mA load change, critical for stable reference accuracy |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact discharge) - protects against human-body and assembly-line electrostatic events without external TVS |
| Reverse Current (IR) | ≤0.1 μA at VR = 60 V - minimizes standby power loss in always-on automotive modules |
| Junction Temperature (Tj) | −55 °C to +175 °C - supports operation in engine bay, transmission control, and under-hood electronics |
| AEC-Q101 Qualified | Stress-tested per Automotive Electronics Council standard - validated for reliability in automotive production applications |
Pinout & Package
HPZR-C63-QX uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, low-profile flat leads, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse-bias current during regulation |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| High Surge Power Handling | 800 W non-repetitive peak power (tp ≤ 100 µs) - absorbs load-dump transients in 12 V/24 V automotive systems |
| Low Thermal Resistance | Rth(j-sp) = 18 K/W - enables direct thermal coupling to PCB copper, reducing need for thermal vias or external heatsinks |
| Precision Voltage Tolerance | ±5 % nominal 63 V - eliminates need for post-production trimming in cost-sensitive automotive modules |
| Automotive-Grade Reliability | AEC-Q101 qualified with 175 °C max junction temperature - meets lifetime requirements for engine control units and ADAS power domains |
| Ultra-Low Leakage | 0.1 μA max reverse current at 60 V - preserves battery life in always-on vehicle subsystems (e.g., telematics, alarm controllers) |
Applications
| Engine Control Unit (ECU) Power Rail Clamping | Automotive Battery Management System (BMS) Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C62 | 62 V nominal, 300 mW Ptot, SOT23 package, RZ = 100 Ω | Limited to low-power signal-level regulation; unsuitable for >100 mA continuous loads or automotive transients | Select only for non-automotive, low-current biasing where footprint and cost outweigh surge capability |
| 1N5388B | 63 V nominal, 5 W Ptot, DO-15 through-hole, RZ = 45 Ω, no AEC-Q101 qualification | Requires wave soldering and board real estate; lacks ESD robustness and automotive reliability validation | Use only in legacy industrial designs where SMT conversion is not feasible and AEC compliance is unnecessary |
Compared with BZX84-C62 and 1N5388B, HPZR-C63-QX delivers 18× higher power dissipation than the SOT23 part and integrates AEC-Q101 qualification and 30 kV ESD protection unavailable in the DO-15 device - making it the sole choice for new automotive SMT designs requiring 63 V regulation with production-grade reliability.

FAQ
What is the maximum continuous forward current rating for HPZR-C63-QX?
The HPZR-C63-QX is a Zener diode intended for reverse-bias operation; its forward current rating is not a functional parameter. However, per datasheet limiting values, the absolute maximum non-repetitive peak forward current is 50 A (8.3 ms half-sine), and the maximum continuous forward current is not specified because forward conduction is outside its intended operating region.
Can HPZR-C63-QX be used as a replacement for a 1N5388B in an existing design?
Yes, HPZR-C63-QX matches the 63 V nominal Zener voltage and exceeds the 1N5388B's 5 W power rating with 5.5 W capability. However, it requires re-layout for CFP3 (SOD123W) footprint and supports reflow-only assembly. Its AEC-Q101 qualification and 30 kV ESD rating provide enhanced reliability over the legacy DO-15 part.
What is the recommended PCB pad layout for HPZR-C63-QX?
Nexperia specifies a reflow footprint with 1.1 mm × 1.1 mm solder lands, 1.2 mm × 1.4 mm solder resist opening, and 0.1 mm stencil thickness. A 1 cm² cathode-side copper pad is required to achieve the rated 5.5 W dissipation at Tsp = 75 °C; smaller pads reduce thermal performance proportionally.
Does HPZR-C63-QX require derating above 75 °C solder point temperature?
Yes - total power dissipation must be linearly derated above 75 °C solder point temperature. Per Figure 9, Ptot decreases from 5.5 W at 75 °C to 0 W at 150 °C. At 100 °C Tsp, maximum allowable Ptot is approximately 3.7 W, based on the published derating curve.
