Product details
Overview
HZM9.1NB1JTL 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 9.1 V (min 9.45 V, max 9.87 V at IZ = 5 mA), with dynamic resistance of 30 Ω, power dissipation up to 200 mW, and operates within –55°C to +150°C storage range - commonly used in voltage reference rails for sensor signal conditioning and power supply feedback loops.
For engineers reviewing the HZM9.1NB1JTL datasheet, HZM9.1NB1JTL pinout, HZM9.1NB1JTL application, or HZM9.1NB1JTL equivalent, key selection criteria include its B1-grade zener tolerance (±2.2% at 9.1 V), MPAK surface-mount package compatibility with high-density PCB layouts, temperature coefficient of +0.03 mV/°C, and suitability for low-current (<5 mA) stabilization where thermal drift and dynamic impedance are critical.
Technical Context
The HZM9.1NB1JTL employs a silicon epitaxial planar junction structure optimized for stable reverse-breakdown behavior under DC and pulsed conditions (Pw = 40 ms). Its zener voltage is specified at IZ = 5 mA with tight grading (B1: 9.45–9.87 V), and it exhibits a positive temperature coefficient (+0.03 mV/°C) typical of mid-voltage Zeners (~6–10 V).
This device operates as a two-terminal shunt regulator with no control logic or bias circuitry. It requires an external current-limiting resistor and is rated for junction temperatures up to +150°C, making it suitable for industrial ambient environments where passive voltage referencing must remain stable across thermal transients.

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-C9V1 (Diodes Inc.) | Same nominal VZ (9.1 V), but wider tolerance (±5%), higher rd (60 Ω), SOT-23 package (smaller footprint, no NC pin) | Lacks NC pin; less precise regulation; better suited for general-purpose clamping than reference use | Choose when cost and size outweigh precision; avoid where <±3% VZ stability is required |
| MMSZ5240B (ON Semiconductor) | VZ = 10 V (not 9.1 V), ±5% tolerance, rd = 17 Ω, SOD-123 package, Pd = 500 mW | Higher voltage and power rating; unsuitable as direct replacement but usable in 10 V reference designs | Select only if system can accommodate 10 V reference and requires higher power margin |
Compared with BZX84-C9V1 and MMSZ5240B, the HZM9.1NB1JTL offers superior voltage accuracy (±2.2% vs. ±5%) and lower thermal drift, making it preferable for precision analog references - though its NC pin and MPAK footprint require dedicated layout space not needed by SOT-23 alternatives.

FAQ
What is the exact zener voltage range for HZM9.1NB1JTL at 5 mA test current?
The HZM9.1NB1JTL has a guaranteed zener voltage range of 9.45 V to 9.87 V when tested at IZ = 5 mA, corresponding to its B1 grade specification per Renesas datasheet R07DS0358EJ0600. This ±2.2% tolerance enables higher-accuracy voltage referencing than standard-grade Zeners. The HZM9.1NB1JTL achieves this precision through controlled epitaxial doping and laser trimming during manufacturing.
Does HZM9.1NB1JTL have a functional third pin, and how should Pin 1 be handled in PCB layout?
No - Pin 1 of the HZM9.1NB1JTL is a No Connect (NC) terminal with no internal electrical connection. It must remain unconnected in both schematic symbol and PCB layout; routing traces to or placing solder paste on Pin 1 may cause mechanical stress or assembly defects. The functional terminals are Pin 2 (Anode) and Pin 3 (Cathode), arranged top-view as 2–1–3.
What is the maximum allowable power dissipation for HZM9.1NB1JTL at 70°C ambient temperature?
Per Figure 3 in the Renesas datasheet, the HZM9.1NB1JTL's power dissipation derates linearly above 25°C ambient. At Ta = 70°C, its maximum continuous power dissipation is approximately 140 mW - calculated using the 200 mW base rating and thermal resistance slope of ~1.33 mW/°C. Exceeding this risks junction temperature exceeding 150°C and long-term reliability degradation.
How does the temperature coefficient of HZM9.1NB1JTL compare to other Zeners in the HZM-N series?
The HZM9.1NB1JTL exhibits a temperature coefficient of +0.03 mV/°C, consistent with mid-voltage Zeners (6–10 V) in the HZM-N series. This is significantly more stable than low-voltage types (e.g., HZM3.3N: –0.02 mV/°C) and less drift-prone than high-voltage variants (e.g., HZM24N: +0.09 mV/°C), making the HZM9.1NB1JTL especially suitable for applications requiring minimal thermal drift around 9 V.
Is HZM9.1NB1JTL compliant with RoHS and REACH regulations?
Yes - the HZM9.1NB1JTL is RoHS-compliant (lead-free terminations, compliant with EU Directive 2011/65/EU) and REACH-conformant, as confirmed by Renesas Electronics' environmental compliance documentation referenced in the datasheet footer. It contains no SVHC substances above threshold levels and is suitable for commercial and industrial equipment sold in regulated markets.
