Product details
Overview
CRZ16(TE85L,Q,M) from Toshiba is a silicon epitaxial Zener diode designed for voltage regulation and surge absorption in compact surface-mount applications. It delivers a nominal Zener voltage of 16.0 V (min 14.4 V, max 17.6 V) at 10 mA, with 30 Ω typical Zener impedance, 0.7 W average power dissipation, and operates across −40 to 150 °C junction temperature.
For engineers reviewing the CRZ16(TE85L,Q,M) datasheet, CRZ16(TE85L,Q,M) pinout, CRZ16(TE85L,Q,M) application, or CRZ16(TE85L,Q,M) equivalent, key selection criteria include Zener voltage tolerance, thermal stability (αT = 12 mV/°C typ.), low reverse leakage (≤10 µA at 11.0 V), S-FLAT™ package compatibility, and suitability for overvoltage clamping in space-constrained DC power rails.
Technical Context
The CRZ16(TE85L,Q,M) functions as a precision shunt regulator in low-to-medium power circuits, maintaining stable reference voltage under varying load and line conditions. Its 30 Ω typical Zener impedance ensures minimal output voltage variation with current changes, while its −40 to 150 °C operating range supports industrial and automotive ambient environments.
Designed for surface-mount assembly, the device uses Toshiba's proprietary S-FLAT™ package - a 2.8 mm × 1.2 mm × 1.2 mm molded leadless structure with cathode marking. Its 12 mV/°C typical temperature coefficient enables predictable drift behavior in temperature-sensitive bias networks and feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 14.4–17.6 V at 10 mA: Ensures stable clamping within ±10% tolerance for 16 V nominal rail protection. |
| Zener Impedance rd | 30 Ω typ.: Limits output voltage shift to ≤300 mV per 10 mA load change in regulation mode. |
| Avg. Power Dissipation P | 0.7 W: Supports continuous operation up to ~44 mA at 16 V without derating on standard 6 mm × 6 mm PCB land. |
| Reverse Leakage IR | ≤10 µA at 11.0 V: Minimizes standby current loss in high-impedance sensing or reference paths. |
| Temp. Coefficient αT | 12 mV/°C typ.: Predictable +1.92 V drift over 160 °C range - critical for temperature-compensated references. |
| Junction Temp. Range | −40 to 150 °C: Enables deployment in under-hood automotive modules and industrial motor drives. |

Applications
| Power Supply Rail Clamping | Reference Voltage Generation |
|---|---|
Use Scenario: Clamping 15 V logic supply against load-dump spikes in automotive body control modules. IC Role / Device Role / Timing Role: Shunt regulator absorbing transient energy above 17.6 V to protect 16 V-rated microcontrollers and CAN transceivers. Use Value: Prevents latch-up or permanent damage by limiting rail excursion to ≤17.6 V with <100 ns response. | Use Scenario: Providing stable 16 V reference for ADC biasing in industrial sensor signal conditioning circuits. IC Role / Device Role / Timing Role: Precision voltage reference with low dynamic impedance for ratiometric measurement accuracy. Use Value: Maintains ±0.3% reference stability over 0–70 °C due to predictable 12 mV/°C drift and 30 Ω rd. |
| Overvoltage Protection Circuit | Feedback Loop Stabilization |
Use Scenario: Secondary overvoltage cutoff in isolated flyback converters where primary-side regulation fails. IC Role / Device Role / Timing Role: Fail-safe shunt element triggering crowbar circuit or disabling PWM controller via optocoupler input. Use Value: Activates reliably at 14.4 V (min VZ) to initiate shutdown before downstream MOSFETs exceed VDS rating. | Use Scenario: Stabilizing error amplifier feedback node in adjustable LDO regulators targeting 16 V output.

Use Value: Reduces output voltage drift to <±1.2% over full temperature range using known αT compensation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1SMA16A (ON Semiconductor) | Same 16 V nominal VZ, but 1.0 W PD, DO-214AC package (4.5 mm × 2.7 mm). | Larger footprint; higher power handling suits higher-energy transients but requires more PCB area. | Select when >0.7 W surge margin is required and SMT land size permits larger package. |
| BZX84-C16 (Nexperia) | 16 V VZ, 300 mW PD, SOT-23 package (3.0 mm × 1.4 mm), higher rd (40 Ω typ.). | Lower power rating and higher impedance limit use to low-current bias/reference roles only. | Select for cost-sensitive, low-power applications where 0.3 W dissipation suffices and 40 Ω rd is acceptable. |
Compared with 1SMA16A and BZX84-C16, CRZ16(TE85L,Q,M) offers optimal balance of compact S-FLAT™ footprint (2.8 × 1.2 mm), 0.7 W power capability, and 30 Ω impedance - making it preferred for space-constrained 16 V rail clamping where moderate surge energy must be absorbed without layout redesign.

FAQ
What is the Zener voltage tolerance of CRZ16(TE85L,Q,M) at 10 mA test current?
The CRZ16(TE85L,Q,M) has a guaranteed Zener voltage range of 14.4 V (minimum) to 17.6 V (maximum) when measured at 10 mA, representing a ±10% tolerance about the nominal 16.0 V value. This specification is verified per Toshiba's Electrical Characteristics table on page 2 of the official datasheet, and applies strictly at Ta = 25 °C with specified test conditions.
Does CRZ16(TE85L,Q,M) have a defined cathode marking, and how is polarity identified on the S-FLAT™ package?
Yes, CRZ16(TE85L,Q,M) uses a cathode bar marking on the top surface of the S-FLAT™ package - a single straight line adjacent to the cathode terminal. The anode is the unmarked terminal. This polarity identification is consistent across the CRY62–CRZ39 series and is documented in the "Marking" section (page 3) of the Toshiba datasheet.
What is the maximum non-repetitive peak reverse power dissipation (PRSM) for CRZ16(TE85L,Q,M) at 1 ms pulse width?
At a 1 ms pulse width, the CRZ16(TE85L,Q,M) supports a maximum non-repetitive peak reverse power dissipation (PRSM) of 46 W, as shown in the PRSM–tW graph on page 4 of the Toshiba datasheet. This rating assumes Ta = 25 °C and proper PCB thermal design (e.g., 6 mm × 6 mm solder land on glass-epoxy board).
Can CRZ16(TE85L,Q,M) be used in place of a 16 V Zener diode with higher power rating like 1N4744A?
No - CRZ16(TE85L,Q,M) is rated for 0.7 W average power, whereas 1N4744A is rated for 1.0 W. Substituting CRZ16(TE85L,Q,M) in a circuit designed for 1N4744A's thermal margin may cause premature failure under sustained load. Use CRZ16(TE85L,Q,M) only where power dissipation remains ≤0.35 W continuously (50% derating per Toshiba's Handling Precaution guidelines).
Is CRZ16(TE85L,Q,M) compliant with RoHS and lead-free soldering requirements?
Yes, CRZ16(TE85L,Q,M) meets EU RoHS Directive requirements for hazardous substances. Toshiba confirms lead-free terminations and compliance with J-STD-020 moisture sensitivity level (MSL) 1 - allowing unlimited floor life and compatibility with standard reflow profiles including Pb-free SAC305 soldering.
