Product details
Overview
SMCJ160AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 160 V standoff voltage (VWM), 259 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with a 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMCJ160AHE3/9AT datasheet, SMCJ160AHE3/9AT pinout, SMCJ160AHE3/9AT application, or SMCJ160AHE3/9AT equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AB (SMC) package compatibility, low incremental surge resistance, and verified clamping performance under repetitive transients induced by inductive switching.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 178–197 V breakdown range (VBR at 1 mA). Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ps), enabling effective suppression of ESD, lightning-induced surges, and load-dump transients.
Thermally, it supports operation from –55 °C to +150 °C with RθJA = 75 °C/W and RθJL = 15 °C/W, and is rated for 200 A non-repetitive forward surge (IFSM, 8.3 ms half-sine). The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 178–197 V at 1 mA - Confirmed avalanche initiation range for reliable overvoltage triggering |
| VC (Clamping Voltage) | 259 V at 5.8 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge |
| PPPM (Peak Pulse Power) | 1500 W - Energy-handling capacity for standardized transient waveforms per IEC 61000-4-5 |
| ID (Reverse Leakage) | ≤1.0 µA at 160 V - Minimal standby power loss and signal integrity impact in high-impedance circuits |
| TJ max. | +150 °C - Enables use in under-hood automotive environments and thermally constrained PCB layouts |
| Package | SMC (DO-214AB) - Industry-standard 2-pin surface-mount outline with 8.0 mm × 8.0 mm copper pad thermal requirement |
Pinout & Package
SMCJ160AHE3/9AT uses the SMC (DO-214AB) package: a rectangular surface-mount case with coplanar matte tin-plated leads, polarity indicated by a cathode band on the body. Thermal performance requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal per Vishay's layout recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage rail; defines conduction path during reverse-biased clamping |
| Cathode | High-side surge input node | Connected to protected line (e.g., 12 V supply rail); absorbs transient energy into ground via avalanche breakdown |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power rails |
| 1500 W peak pulse rating | Withstands IEC 61000-4-5 Level 4 (4 kV) surges without degradation when properly mounted |
| Glass-passivated junction | Ensures long-term stability of VBR and leakage across temperature and humidity stress |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns |
| Low clamping ratio (VC/VWM = 1.62) | Minimizes overvoltage exposure to downstream components compared to higher-ratio TVS devices |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between power input and bulk capacitor to limit voltage excursion to safe levels. Use Value: Clamps to 259 V within nanoseconds, protecting downstream PMICs and microcontrollers rated for ≤36 V absolute maximum. |
Use Scenario: 48 V DC input stage of programmable logic controllers subjected to inductive switching noise from solenoid drivers. IC Role / Device Role / Timing Role: Primary surge suppression device on main power entry, upstream of input filter and converter. Use Value: Absorbs 1500 W pulses without failure, maintaining system uptime where replacement access is limited. |
| Telecom Interface Protection | Sensor Signal Line Guarding |
Use Scenario: RS-485 data lines in outdoor base stations encountering lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Paired unidirectional TVS on each line (with appropriate common-mode choke) to suppress differential and common-mode transients. Use Value: Low capacitance (<100 pF typical) avoids signal integrity degradation at up to 10 Mbps data rates. |
Use Scenario: Analog output lines of pressure/temperature sensors in factory automation systems near motor drives. IC Role / Device Role / Timing Role: Localized TVS at sensor connector to shunt fast-rising EFT bursts (IEC 61000-4-4) before reaching ADC front-end. Use Value: Sub-µA leakage preserves mV-level signal accuracy; 259 V clamping prevents op-amp saturation or latch-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160AHE3/52T | Lower PPPM (600 W), SMB (DO-214AA) package, same VWM/VBR/VC specs | Reduced surge margin; suitable only for lower-energy threats or space-constrained layouts | Select when board area is critical and surge threat level is ≤Level 3 per IEC 61000-4-5 |
| SMCJ160CAHE3/9AT | Bidirectional variant; identical VWM/VBR/VC but symmetric clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal may occur | Choose for RS-232, CAN, or Ethernet PHY protection where bidirectional clamping is mandated |
Compared with SMBJ160AHE3/52T and SMCJ160CAHE3/9AT, the SMCJ160AHE3/9AT delivers optimal balance of high-energy handling (1500 W), automotive qualification, and unidirectional precision - making it preferred for primary DC rail protection where polarity is fixed and surge severity is high.

FAQ
What is the clamping voltage of SMCJ160AHE3/9AT at its rated peak pulse current?
The SMCJ160AHE3/9AT has a maximum clamping voltage (VC) of 259 V when subjected to its specified peak pulse current (IPPM) of 5.8 A under a 10/1000 µs waveform. This value is measured per JEDEC standards and guarantees the protected circuit will not experience more than 259 V during such a transient event - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Is SMCJ160AHE3/9AT qualified for automotive applications?
Yes, SMCJ160AHE3/9AT is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - validating its suitability for under-hood and chassis-mounted automotive modules including body control units, lighting drivers, and infotainment power supplies.
What package does SMCJ160AHE3/9AT use, and what are its mounting requirements?
SMCJ160AHE3/9AT uses the SMC (DO-214AB) surface-mount package. Per Vishay's datasheet, optimal thermal performance requires mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. The device is MSL Level 1 compliant and compatible with standard lead-free reflow profiles peaking at 260 °C.
How does the unidirectional configuration of SMCJ160AHE3/9AT affect its circuit placement?
The unidirectional configuration of SMCJ160AHE3/9AT means it conducts only when the cathode is positive relative to the anode - so it must be placed with cathode toward the protected line and anode to ground. This orientation enables precise clamping of positive-going transients while blocking normal forward bias, unlike bidirectional variants that protect both polarities.
What is the maximum operating temperature range for SMCJ160AHE3/9AT?
SMCJ160AHE3/9AT is rated for an operating junction and storage temperature range of –55 °C to +150 °C. This wide range supports deployment in extreme environments such as automotive engine compartments, industrial motor controls, and outdoor telecom enclosures - with thermal derating applied above 25 °C ambient per Figure 2 in the datasheet.
