Product details
Overview
5.0SMDJ16A from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and I/O interfaces. It features a 16 V working standoff voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage at 193 A peak pulse current, and 5000 W peak pulse power rating at 10/1000 µs waveform - enabling robust protection for 12–15 V automotive and industrial power rails.
For engineers reviewing the 5.0SMDJ16A datasheet, 5.0SMDJ16A pinout, 5.0SMDJ16A application, or 5.0SMDJ16A equivalent, key selection criteria include clamping performance under 193 A surge, thermal resistance (RθJL = 16 °C/W), DO-214AB (SMC) package compatibility with automated placement, and unidirectional polarity indicated by cathode band - all critical for reliable overvoltage hardening in compact PCB layouts.
Technical Context
The 5.0SMDJ16A employs a stacked-die construction to achieve high peak pulse power handling while maintaining fast response (<1.0 ps) and low clamping ratio (VC/VBR ≈ 1.46). Its unidirectional configuration provides forward conduction capability (VF = 5 V @ 100 A), supporting bidirectional surge suppression when paired with complementary devices or used in DC-biased signal paths.
Designed for operation across –55 °C to +175 °C junction temperature range, it leverages glass-passivated junctions and matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Moisture sensitivity level is rated at MSL 1 per J-STD-020 - eliminating bake requirements prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before leakage exceeds 50 µA; defines upper limit of protected circuit's normal DC bias. |
| VBR min/max | 17.8–19.7 V @ 1 mA - verified breakdown threshold ensures predictable turn-on during transients without premature conduction. |
| VC @ IPP | 26.0 V @ 193 A - clamping voltage limits downstream component stress during 10/1000 µs surge; enables safe operation of 24 V-rated ICs. |
| PPPM | 5000 W - peak pulse power dissipation capability supports IEC 61000-4-5 Level 4 (4 kV) surge immunity testing. |
| RθJL | 16 °C/W - low junction-to-lead thermal resistance allows efficient heat transfer to PCB copper pads, sustaining repeated surges without thermal runaway. |
| TJ max | +175 °C - extended junction temperature rating supports under-hood automotive and high-ambient industrial deployments. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, unidirectional configuration with cathode band marking. Weight: 0.300 g. UL 94V-0 molded compound. Matte tin-plated leads, J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connects to lower-potential side of protected line; enables 5 V forward drop at 100 A for DC fault current limiting. |
| Cathode | Current exit point; marked by band | Connects to higher-potential side (e.g., VIN); defines polarity-sensitive clamping direction for reverse transients. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device compliance with IEC 61000-4-5 surge test requirements up to 4 kV on 2 Ω source impedance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Lower peak power (600 W), same DO-214AA package, 28.5 V clamping at 21.2 A | Not suitable for IEC 61000-4-5 Level 4; limited to low-energy ESD or data-line protection | Select only if surge current <25 A and layout space restricts larger SMC footprint. |
| SMCJ16A | Same 5000 W rating and DO-214AB package, but 27.5 V clamping at 182 A (higher VC) | Marginally higher clamping voltage reduces protection margin for 24 V systems with tight VIH tolerances | Acceptable where 27.5 V clamping is within downstream IC specs; verify thermal derating curves match. |
Compared with SMBJ16A and SMCJ16A, the 5.0SMDJ16A delivers superior clamping performance (26.0 V vs. ≥27.5 V) at full 193 A rating while maintaining identical DO-214AB mechanical fit - making it the preferred choice for high-reliability 12–24 V power rail protection where voltage margin and thermal stability are critical.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ16A under standard test conditions?
The 5.0SMDJ16A has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 193 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C and represents the upper voltage limit imposed on the protected circuit during surge events - critical for ensuring downstream components remain within their absolute maximum ratings. The 5.0SMDJ16A achieves this clamping performance while maintaining a low VBR/VC ratio of approximately 1.46.
Is the 5.0SMDJ16A suitable for automotive under-hood applications?
Yes, the 5.0SMDJ16A is suitable for automotive under-hood applications due to its guaranteed operation from –55 °C to +175 °C junction temperature, glass-passivated junction, and AEC-Q200-aligned construction. Its 5000 W peak pulse rating and 26.0 V clamping support load dump and ISO 7637-2 pulse 5a/b compliance. The 5.0SMDJ16A also meets MSL 1 per J-STD-020, eliminating bake requirements before reflow - essential for high-throughput automotive module assembly.
Does the 5.0SMDJ16A have polarity markings, and how is it oriented on the PCB?
Yes, the 5.0SMDJ16A uses a cathode band marking to indicate polarity, consistent with DO-214AB (SMC) industry convention. During PCB layout, the cathode (banded end) must connect to the higher-potential node (e.g., VIN or power rail), and the anode to ground or lower potential. This orientation enables unidirectional clamping of reverse transients while permitting forward conduction during overcurrent faults. The 5.0SMDJ16A's polarity marking is laser-etched and visible under standard AOI inspection.
What is the thermal resistance from junction to lead (RθJL) for the 5.0SMDJ16A, and why does it matter?
The 5.0SMDJ16A has a typical junction-to-lead thermal resistance (RθJL) of 16 °C/W when mounted on a 16 mm × 16 mm copper pad test board. This low value enables rapid heat transfer from the silicon die to the PCB copper, preventing thermal runaway during repetitive surge events. For designs expecting multiple transients per minute, RθJL directly determines allowable power dissipation - making the 5.0SMDJ16A more robust than alternatives with higher RθJL under sustained stress.
How does the 5.0SMDJ16A compare to the 5.0SMDJ16CA variant?
The 5.0SMDJ16A is unidirectional, while the 5.0SMDJ16CA is bidirectional - meaning the latter clamps transients of either polarity but lacks forward conduction capability. The 5.0SMDJ16A exhibits VF = 5 V @ 100 A in forward bias, useful for DC fault current limiting, whereas the 5.0SMDJ16CA has symmetrical VBR (~17.8 V) in both directions and no defined forward voltage. Select 5.0SMDJ16A for DC-biased lines like power rails; choose 5.0SMDJ16CA only for AC-coupled or floating signal lines.
