Product details
Overview
HZU15B2TRF-E from Renesas Electronics is a silicon planar Zener diode in ultra-small resin package (URP/SC-76A) designed for precision voltage stabilization in low-power analog and digital supply rails. It delivers a nominal Zener voltage of 15.0 V (min 14.85 V, max 15.52 V) at 5 mA test current, with dynamic resistance of 40 Ω, power dissipation rating of 200 mW, and junction temperature limit of 150 °C - suitable for voltage reference and overvoltage protection in portable instrumentation.
For engineers reviewing the HZU15B2TRF-E datasheet, HZU15B2TRF-E pinout, HZU15B2TRF-E application, or HZU15B2TRF-E equivalent, key selection criteria include its B2-grade voltage tolerance (±1.7% at 15 V), surface-mount URP footprint (1.5 × 0.8 × 0.4 mm), cathode-anode polarity marking, low leakage (<2 µA at VR = 12.0 V), and thermal derating behavior per Fig.3.
Technical Context
The HZU15B2TRF-E operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load currents by conducting reverse-biased Zener breakdown. Its planar silicon construction ensures consistent breakdown characteristics and low temperature coefficient (≈+0.04 %/°C near 15 V, per Fig.2).
Designed for DC biasing and reference applications, it requires external series current limiting and exhibits specified performance only under pulsed test conditions (PW = 40 ms). The device is not rated for surge or transient suppression beyond its absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.85 V to 15.52 V at IZ = 5 mA - defines stable regulation range for precision 15 V references |
| 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 DC power before thermal derating applies |
| Reverse Current (IR) | ≤2 µA at VR = 12.0 V - indicates low leakage in sub-Zener bias region |
| Junction Temperature (Tj) | 150 °C max - constrains PCB layout and ambient operating envelope for reliability |
| Package | URP (SC-76A), 1.5 × 0.8 × 0.4 mm - enables high-density SMT placement on space-constrained boards |

Applications
| Portable Sensor Signal Conditioning | Low-Power Microcontroller Reset Circuit |
|---|---|
Use Scenario: Stabilizing reference voltage for 12-bit ADCs in battery-powered environmental sensors. IC Role / Device Role / Timing Role: Shunt voltage reference providing stable 15 V bias to op-amp gain stages and ADC reference inputs. Use Value: Maintains ±0.5 LSB linearity over 0–50 °C due to low dynamic resistance (40 Ω) and predictable temperature coefficient. |

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 |
|---|---|---|---|
| BZX84-C15LT1G | 15 V ±5% (C-grade), SOT-23 package (2.9 × 1.3 × 1.0 mm), Pd = 300 mW, rd = 30 Ω | Larger footprint and looser tolerance; better power handling but less precision | Select when higher power margin (>200 mW) is required and ±5% regulation suffices |
| MMSZ5245B-TP | 15 V ±5%, SOD-123 package (3.7 × 1.6 × 1.1 mm), Pd = 500 mW, rd = 25 Ω | Higher power rating and lower rd, but 2.3× larger board area and no B2-grade option | Choose for cost-sensitive industrial designs where size is secondary to robustness and availability |
Compared with BZX84-C15LT1G and MMSZ5245B-TP, the HZU15B2TRF-E offers superior voltage accuracy (±1.7% vs. ±5%) and minimal footprint (1.5 × 0.8 mm), making it optimal for space-constrained, high-precision reference designs - though it requires stricter thermal management due to its 200 mW limit.

FAQ
What is the Zener voltage tolerance of HZU15B2TRF-E?
The HZU15B2TRF-E has a B2-grade Zener voltage specification of 14.85 V to 15.52 V at 5 mA test current, corresponding to ±1.7% tolerance around the nominal 15.0 V value. This tighter tolerance than standard B-grade devices makes HZU15B2TRF-E suitable for applications demanding higher reference accuracy without trimming components.
Can HZU15B2TRF-E be used in continuous DC operation?
Yes, HZU15B2TRF-E is rated for continuous DC operation up to 200 mW at 25 °C ambient, but must be thermally derated per Fig.3 in the datasheet. At 60 °C ambient, its usable power drops to ~140 mW. Pulse testing (40 ms) was used for parameter characterization, but the device is fully qualified for steady-state shunt regulation when heat sinking and layout comply with its thermal limits.
What does the "TRF" suffix indicate in HZU15B2TRF-E?
The "TRF" suffix in HZU15B2TRF-E denotes tape-and-reel packaging with 3,000 units per reel, using the TRF taping abbreviation defined in the ordering information table. It confirms factory-standard SMT-compatible packaging optimized for automated assembly - distinct from bulk or ammo-pack variants.
How is polarity marked on the HZU15B2TRF-E package?
The HZU15B2TRF-E uses a cathode mark (a visible band or dot) adjacent to Pin 1, which is the cathode terminal. Pin 2 is the anode. This marking aligns with standard diode polarity conventions and is clearly shown in the "Pin Arrangement" diagram on page 1 of the R07DS0423EJ1000 datasheet.
Is HZU15B2TRF-E RoHS compliant?
Yes, HZU15B2TRF-E complies with the EU RoHS Directive, as confirmed by Renesas Electronics' environmental compliance documentation. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits, and is suitable for use in consumer and industrial electronics markets requiring RoHS conformance.
