Product details
Overview
SMBJ160AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 160 V standoff voltage (VWM), 178–197 V breakdown range (VBR at 1 mA), 259 V clamping voltage (VC) at 2.3 A peak pulse current, and 600 W peak pulse power (10/1000 µs waveform), targeting protection of MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ160AHE3/52 datasheet, SMBJ160AHE3/52 pinout, SMBJ160AHE3/52 application, or SMBJ160AHE3/52 equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, clamping performance under 10/1000 µs transients, and thermal resistance (RθJA = 100 °C/W) in standard PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 160 V), but triggers avalanche conduction when transient voltage exceeds its breakdown threshold, diverting surge current away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surges.
Designed for automated SMT assembly, SMBJ160AHE3/52 uses a low-profile SMB (DO-214AA) package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It meets MSL Level 1 (260 °C reflow peak) and is AEC-Q101 qualified-making it suitable for automotive power rail and body electronics where transient immunity and process consistency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - Maximum continuous reverse operating voltage before significant leakage; defines upper limit of protected circuit's nominal DC rail. |
| VBR (Breakdown Voltage) | 178–197 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system operating voltage with margin. |
| VC (Clamping Voltage) | 259 V at IPPM = 2.3 A (10/1000 µs) - Peak voltage seen by protected device during worst-case surge; directly limits stress on downstream ICs or MOSFETs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capability under standardized 10/1000 µs transient; validates suitability for IEC 61000-4-5 Level 3/4 surges. |
| RθJA (Junction-to-Ambient) | 100 °C/W - Thermal resistance with recommended 0.2" × 0.2" copper pads; enables derating calculations for ambient temperatures up to +85 °C. |
| TJ max. | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive or industrial enclosures without active cooling. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for powertrain and chassis ECUs. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for solderability per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to ground or lower-potential node in unidirectional configuration; must be routed with low-inductance path to handle surge return current. |

FAQ
What is the clamping voltage of SMBJ160AHE3/52 and how is it measured?
The SMBJ160AHE3/52 has a maximum clamping voltage (VC) of 259 V, measured at a peak pulse current (IPPM) of 2.3 A using the standardized 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value represents the highest voltage imposed on the protected circuit during a worst-case transient event and is confirmed per Vishay Document Number 88392, page 2.
Is SMBJ160AHE3/52 compatible with lead-free reflow processes?
Yes, SMBJ160AHE3/52 is fully compatible with lead-free reflow soldering. It meets MSL Level 1 per J-STD-020 with a maximum peak temperature of 260 °C, and its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 for reliable wetting and intermetallic formation. The device requires no pre-bake for standard SMT assembly.
Does SMBJ160AHE3/52 have bidirectional capability?
No, SMBJ160AHE3/52 is a unidirectional TVS diode. Its polarity is defined by the cathode band marking, and it conducts only during reverse-bias overvoltage events. For bidirectional protection at the same voltage level, the correct variant is SMBJ160CAHE3/52, which provides symmetrical clamping in both directions.
What is the maximum operating temperature for SMBJ160AHE3/52?
The SMBJ160AHE3/52 has a maximum junction temperature (TJ) of +150 °C and an operating storage temperature range of –55 °C to +150 °C. When mounted on the recommended 0.2" × 0.2" copper pads, its thermal resistance (RθJA) is 100 °C/W, allowing continuous operation at ambient temperatures up to +85 °C with appropriate power derating per Figure 2 in Vishay Document 88392.
How does the AEC-Q101 qualification of SMBJ160AHE3/52 impact its use in automotive designs?
The AEC-Q101 qualification of SMBJ160AHE3/52 confirms it has passed accelerated stress tests-including high-temperature reverse bias (HTRB), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST)-required for automotive electronic control units. This enables direct use in BCMs, ADAS power stages, and infotainment systems without additional qualification effort by the end customer.
