Product details
Overview
HZU10B1TRF-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, featuring a nominal Zener voltage of 10.44 V to 10.88 V at 5 mA, 7.0 Ω dynamic resistance, and 200 mW power dissipation in an ultra-small URP (SC-76A) surface-mount package.
For engineers reviewing the HZU10B1TRF-E datasheet, HZU10B1TRF-E pinout, HZU10B1TRF-E application, or HZU10B1TRF-E equivalent, this device serves as a compact, tape-and-reel–ready voltage reference for power supply regulation, overvoltage protection, and analog signal conditioning where tight voltage tolerance and thermal stability are required.
Technical Context
The HZU10B1TRF-E operates as a two-terminal, reverse-biased Zener diode with graded doping to achieve stable breakdown at precisely defined current conditions. Its Zener voltage is specified at IZ = 5 mA with ±4.2% tolerance (10.44 V to 10.88 V), and it exhibits a positive temperature coefficient near +0.04 %/°C per the series' characteristic curve.
Designed for surface-mount assembly, the device uses silicon planar construction with glass-passivated junctions and is rated for junction temperatures up to 150°C. It delivers stable regulation under pulsed test conditions (PW = 40 ms) and maintains low dynamic impedance (7.0 Ω max) to minimize output voltage variation under load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.44 V to 10.88 V at IZ = 5 mA - defines precise regulation point for reference and clamp applications |
| Dynamic Resistance (rd) | 7.0 Ω max at IZ = 5 mA - ensures minimal output voltage shift under small-signal load variations |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC or pulsed power handling in PCB layout |
| Reverse Current (IR) | 2 μA max at VR = 7.0 V - guarantees low leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 150°C max - enables reliable operation in thermally constrained industrial and automotive-adjacent environments |
| Package | URP (SC-76A), 2-pin surface-mount - supports automated placement and high-density board layouts |
| Temperature Coefficient (γZ) | +0.04 %/°C typical - provides predictable, low-drift voltage reference behavior across operating range |
Pinout & Package

| 2 | Anode | Connected to lower-potential node (typically ground or return path); completes bias circuit |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small URP package | Enables placement in space-constrained PCB areas (<1.3 mm² footprint) without sacrificing thermal derating margin |

|---|---|---|---|
| BZX84-C10LT1G | 10 V nominal (9.4–10.6 V), SOT-23 package, 350 mW Pd, 15 Ω rd | Higher power and larger footprint; less precise regulation but better surge handling | Select when higher pulse energy absorption or compatibility with existing SOT-23 footprints is required |
| MMSZ5240B-TP | 10 V nominal (9.5–10.5 V), SOD-123 package, 500 mW Pd, 17 Ω rd | Larger package, higher power, wider tolerance, higher dynamic impedance | Prefer for cost-sensitive, non-precision applications where board space is not constrained |

FAQ
What is the Zener voltage tolerance of HZU10B1TRF-E?
The HZU10B1TRF-E has a Zener voltage range of 10.44 V to 10.88 V at IZ = 5 mA, corresponding to a ±4.2% tolerance (B1 grade). This tighter specification than standard B-grade devices makes HZU10B1TRF-E suitable for applications demanding higher initial accuracy without trimming.
Is HZU10B1TRF-E compatible with reflow soldering processes?
Yes, HZU10B1TRF-E is qualified for standard lead-free reflow soldering per J-STD-020. Its URP package withstands peak temperatures up to 260°C for 10 seconds. Thermal profile must respect the 150°C maximum junction temperature limit during sustained operation after assembly.
What is the maximum reverse leakage current for HZU10B1TRF-E?
The HZU10B1TRF-E specifies a maximum reverse leakage current (IR) of 2 μA at VR = 7.0 V and Ta = 25°C. This low leakage supports use in high-impedance bias networks and battery-operated systems where standby current must be minimized.
Can HZU10B1TRF-E be used in place of a 10 V Zener diode with looser tolerance?
Yes - the HZU10B1TRF-E can replace generic 10 V Zeners in applications benefiting from tighter regulation (±4.2% vs. ±5–10%) and lower dynamic impedance. However, its URP package requires PCB land pattern adjustment versus SOD-123 or SOT-23 footprints, so mechanical compatibility must be verified.
Does HZU10B1TRF-E meet RoHS and REACH requirements?
Yes, HZU10B1TRF-E complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Renesas confirms lead-free terminations and halogen-free molding compound, with full material declarations available upon request for HZU10B1TRF-E.
