Product details
Overview
1.5SMC160A-E3/57T 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), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive power supplies, industrial motor controls, and telecom interface protection.
For engineers reviewing the 1.5SMC160A-E3/57T datasheet, 1.5SMC160A-E3/57T pinout, 1.5SMC160A-E3/57T application, or 1.5SMC160A-E3/57T equivalent, key selection criteria include clamping performance under repetitive transients, thermal derating above 25 °C, unidirectional polarity marking, SMC (DO-214AB) package compatibility with automated placement, and AEC-Q101 qualification status of related variants.
Technical Context
This device operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold (152–168 V at 1 mA test current), thereby shunting transient energy to ground while maintaining low leakage (<1 μA at 136 V). Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repeated surge stress.
The 1.5SMC160A-E3/57T delivers 1500 W peak pulse power handling per 10/1000 μs waveform with <1 ns response time, low incremental surge resistance, and thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads - enabling robust protection without external heat sinking in most board-level deployments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Same VWM (136 V) and VC (219 V), but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 85 °C/W). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); less suitable for automotive load dump. | Select when board space is constrained and surge threat level is moderate (e.g., internal signal lines). |
| 1.5KE160A | Through-hole DO-201 package; identical electrical specs (VWM, VBR, VC, PPPM), but incompatible with SMT assembly. | Requires manual or wave-solder process; not viable for high-volume automated production. | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs automation needs. |
Compared with SMBJ160A and 1.5KE160A, the 1.5SMC160A-E3/57T uniquely balances 1500 W surge capacity, SMT manufacturability, and industry-standard SMC footprint - making it optimal for new automotive and industrial PCBs requiring both high reliability and production scalability.

FAQ
What is the maximum clamping voltage of the 1.5SMC160A-E3/57T under a 10/1000 μs surge?
The 1.5SMC160A-E3/57T has a maximum clamping voltage (VC) of 219 V at 6.8 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 1.5SMC160A-E3/57T maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC160A-E3/57T AEC-Q101 qualified?
No, the 1.5SMC160A-E3/57T is a commercial-grade part with RoHS compliance (E3 suffix) but not AEC-Q101 qualified. For automotive applications requiring AEC-Q101 certification, Vishay offers the 1.5SMC160AHE3_A variant (HE3 suffix), which shares identical electrical specifications but undergoes additional stress testing per AEC-Q101 standards. The 1.5SMC160A-E3/57T remains suitable for industrial and telecom use cases where AEC qualification is not mandated.
What does the "-E3/57T" suffix indicate in 1.5SMC160A-E3/57T?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance. The "57T" specifies packaging: 7-inch diameter plastic tape-and-reel with 850 units per reel. This format supports high-speed pick-and-place assembly and is distinct from the "9AT" (13-inch reel, 3500 units) option. The 1.5SMC160A-E3/57T uses the standard SMC (DO-214AB) package with cathode band marking.
How does thermal derating affect the 1.5SMC160A-E3/57T's surge capability above 25 °C?
The 1.5SMC160A-E3/57T's peak pulse power (PPPM) must be linearly derated above TA = 25 °C per Figure 2 in the datasheet: at 75 °C ambient, PPPM drops to ~850 W (≈57% of 1500 W). This reflects increased junction temperature limiting safe energy absorption. Derating is critical in enclosed enclosures or high-power boards; the 1.5SMC160A-E3/57T's RθJA of 75 °C/W guides heatsink or pad design to maintain TJ ≤ 150 °C during repeated surges.
Can the 1.5SMC160A-E3/57T be used in bidirectional protection circuits?
No - the 1.5SMC160A-E3/57T is strictly unidirectional, indicated by the "A" suffix and cathode band marking. For bidirectional protection (e.g., AC lines or differential data buses), Vishay specifies the "CA" suffix variant, such as 1.5SMC160CA. Using the 1.5SMC160A-E3/57T in reverse-biased configurations risks permanent damage due to forward conduction during negative transients. Always match polarity designation to circuit topology.
