Product details
Overview
HZU16B1URF-E from Renesas Electronics is a silicon planar Zener diode designed for voltage stabilization in low-power analog and power supply regulation circuits, with a nominal Zener voltage of 16.94 V to 17.70 V at 5 mA test current, 40 mW dynamic resistance, and 200 mW maximum power dissipation in an ultra-small URP surface-mount package.
For engineers reviewing the HZU16B1URF-E datasheet, HZU16B1URF-E pinout, HZU16B1URF-E application, or HZU16B1URF-E equivalent, key selection considerations include its B1-grade voltage tolerance (±2.2% at 16.94–17.70 V), low 2 µA reverse leakage at 12.0 V, suitability for space-constrained PCB layouts, and thermal derating behavior above 25°C ambient.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its planar junction construction ensures consistent breakdown characteristics and low noise performance, while the URP package enables high-density mounting on compact PCBs.
Electrical behavior follows standard Zener I-V curve characteristics with defined knee voltage and dynamic resistance. The device is rated for junction temperatures up to 150°C and exhibits a negative temperature coefficient typical of mid-voltage Zeners (~−0.04 %/°C near 16 V), confirmed in Figure 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16.94 V to 17.70 V at IZ = 5 mA - defines precise regulation point for feedback loops or reference generation |
| Dynamic Resistance (rd) | 40 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling before thermal derating applies |
| Reverse Leakage (IR) | 2 µA max at VR = 12.0 V - critical for low-current bias networks where leakage affects accuracy |
| Junction Temperature (Tj) | 150°C maximum - constrains operating ambient range and PCB copper area requirements for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5255B-TP (Micro Commercial) | Zener voltage 16.7 V (±5%), 500 mW Pd, SOD-123 package (2.7 × 1.6 mm) | Larger footprint and looser tolerance; better for higher-power clamping where size is less constrained | Select when higher power margin is needed and PCB real estate permits larger package |
| BZX84-C16LT1G (ON Semiconductor) | Zener voltage 16 V (±5%), 300 mW Pd, SOT-23 package (3.0 × 1.4 mm) | Wider voltage tolerance, higher rd (~50 Ω), larger footprint than URP | Choose for legacy SOT-23 compatibility where B1-grade precision is not required |
Compared with HZU16B1URF-E, MMSZ5255B-TP offers higher power but sacrifices precision and board space efficiency, while BZX84-C16LT1G provides broader industry availability at the cost of voltage accuracy and thermal performance in dense layouts.

FAQ
What is the exact Zener voltage range specified for HZU16B1URF-E?
The HZU16B1URF-E has a guaranteed Zener voltage range of 16.94 V to 17.70 V when tested at IZ = 5 mA and Ta = 25°C. This B1-grade specification reflects ±2.2% tolerance around the nominal 17.3 V center point, as documented in the Electrical Characteristics table on page 2 of R07DS0423EJ1000 Rev.10.00. The HZU16B1URF-E maintains this tight tolerance across its qualified operating temperature range.
Does HZU16B1URF-E support automated SMT assembly?
Yes, the HZU16B1URF-E is supplied in TRF taping format (3,000 pieces per reel) and uses the URP (SC-76A) package compatible with standard 0603-class pick-and-place equipment. Its cathode marking and standardized orientation allow reliable optical recognition and placement. The HZU16B1URF-E's 1.6 mm × 0.8 mm footprint and 0.45 mm profile meet IPC-7351B requirements for ultra-small passive components.
What is the maximum reverse leakage current for HZU16B1URF-E at 12 V?
The maximum reverse leakage current (IR) for HZU16B1URF-E is 2 µA when measured at VR = 12.0 V and Ta = 25°C, as specified in the Electrical Characteristics table. This low leakage ensures minimal error contribution in high-impedance reference or bias networks. The HZU16B1URF-E maintains this performance across its storage temperature range of −55°C to +150°C.
Can HZU16B1URF-E be used in automotive applications?
The HZU16B1URF-E is classified as a "Standard" quality grade device per Renesas' quality policy and is intended for applications including industrial equipment and consumer electronics-not automotive safety-critical systems. While it operates up to 150°C junction temperature, the HZU16B1URF-E lacks AEC-Q200 qualification and is not recommended for under-hood automotive use without additional system-level validation.
How does thermal derating affect HZU16B1URF-E power handling above 25°C?
HZU16B1URF-E power dissipation must be linearly derated above 25°C ambient, as shown in Figure 3 of the datasheet: Pd decreases by approximately 1.6 mW/°C beyond 25°C, reaching zero at ~150°C. At 70°C ambient, usable Pd drops to ~130 mW. This derating directly impacts sustained current capability and must be factored into layout copper area and airflow design for the HZU16B1URF-E.
