Product details
Overview
HZM22NB3TR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 22.7 V (min 22.23 V, max 23.17 V) at 5 mA test current, with dynamic resistance of 55 Ω, power dissipation rating of 200 mW, and operates within –55°C to +150°C storage temperature range.
For engineers reviewing the HZM22NB3TR-E datasheet, HZM22NB3TR-E pinout, HZM22NB3TR-E application, or HZM22NB3TR-E equivalent, key selection considerations include its B3-grade voltage tolerance (±2.4% typical), MPAK surface-mount package compatibility with high-density PCB layouts, thermal stability across industrial ambient conditions, and suitability for feedback regulation in DC-DC converters and sensor biasing networks.
Technical Context
This device uses a silicon epitaxial planar junction structure optimized for stable reverse-breakdown behavior under controlled zener current (IZ = 5 mA). Its temperature coefficient is +0.05 mV/°C near 22 V, enabling predictable drift compensation in voltage references.
The HZM22NB3TR-E operates exclusively in reverse-biased mode with cathode-anode polarity; terminal 1 is NC (no connection), terminal 2 is anode, and terminal 3 is cathode - a configuration validated for noise-sensitive stabilization where floating terminals reduce parasitic coupling.
Key Specifications

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 |
|---|---|---|---|
| MMBZ5255B-7-F (Diodes Inc.) | Zener voltage 22 V ±5%, rd = 50 Ω, Pd = 300 mW, SOT-23 package | Wider voltage tolerance; higher power rating but larger footprint (2.9 × 1.3 mm vs. 2.7 × 1.35 mm) | Preferred when board layout allows SOT-23 and ±5% VZ tolerance is acceptable for cost-sensitive consumer designs |
| BZX84-C22 (Nexperia) | Zener voltage 22 V ±5%, rd = 60 Ω, Pd = 250 mW, SOT-23 package | Same ±5% grade; slightly higher rd increases ripple sensitivity; RoHS-compliant but no AEC-Q200 qualification | Selected for non-automotive industrial use where JEDEC-standard SOT-23 availability and distributor stock depth outweigh tight-tolerance needs |
Compared with MMBZ5255B-7-F and BZX84-C22, the HZM22NB3TR-E offers superior voltage accuracy (±2.4% vs. ±5%) and lower thermal drift in compact MPAK packaging - critical for precision analog signal chains where reference stability directly impacts measurement fidelity.

FAQ
What is the exact zener voltage range for HZM22NB3TR-E at 5 mA?
The HZM22NB3TR-E has a guaranteed zener voltage range of 22.23 V (minimum) to 23.17 V (maximum) when tested at IZ = 5 mA and Ta = 25°C. This B3-grade specification reflects ±2.4% total tolerance around the nominal 22.7 V value, confirmed in Renesas' R07DS0358EJ0600 datasheet page 3.
Does HZM22NB3TR-E have a functional pin 1, and what happens if it's connected?
No - pin 1 of the HZM22NB3TR-E is designated NC (no connection) and must remain unconnected in circuit layout. Connecting pin 1 risks introducing stray capacitance or leakage paths that degrade regulation stability and increase noise susceptibility, as explicitly defined in the "Pin Arrangement" diagram on page 1 of the datasheet.
Can HZM22NB3TR-E be used in place of a standard 22 V Zener like BZX84-C22?
The HZM22NB3TR-E is not a drop-in replacement for BZX84-C22 due to differing voltage tolerance (±2.4% vs. ±5%), package dimensions (MPAK vs. SOT-23), and pinout (NC/anode/cathode vs. anode/cathode/anode). While both regulate near 22 V, substituting requires PCB layout revision and recalibration of feedback networks to accommodate tighter VZ bounds.
What is the maximum allowable reverse current before regulation degrades in HZM22NB3TR-E?
The HZM22NB3TR-E specifies IR ≤ 2 μA maximum at VR = 17.0 V (page 3 of datasheet), meaning regulation remains stable up to this voltage. Beyond 17.0 V, reverse current rises exponentially - sustained operation above 23.17 V risks exceeding Pd = 200 mW and thermal runaway. Designers must limit applied voltage to ≤17.0 V unless actively sinking ≥5 mA through the device.
How does the temperature coefficient of HZM22NB3TR-E affect long-term reference stability?
The HZM22NB3TR-E exhibits a temperature coefficient of +0.05 mV/°C near 22 V (page 5, Fig.2), translating to ~1.1 mV drift over a 22°C span (e.g., 25°C to 47°C). This low, predictable drift enables accurate compensation in precision references - unlike higher-tempco Zeners (>0.1 mV/°C) that introduce nonlinear errors beyond ±2.5 mV across industrial temperature ranges.
