Product details
Overview
SS215H from Taiwan Semiconductor is a 2 A, 150 V Schottky barrier surface-mount rectifier in DO-214AA (SMB) package, featuring 0.95 V forward voltage at 2 A and 25°C, 5 mA reverse current at 150 V and 125°C, and 50 A surge capability - deployed in automotive lighting and DC/DC converter freewheeling paths.
For engineers reviewing the SS215H datasheet, SS215H pinout, SS215H application, or SS215H equivalent, key selection criteria include its AEC-Q101 qualification, junction temperature rating up to +150°C, low VF at high TJ, guard-ring over-voltage protection, and moisture sensitivity level 1 compliance for reflow assembly.
Technical Context
The SS215H is a single-die Schottky rectifier optimized for low-loss, high-frequency operation in automotive and industrial power conversion. Its 150 V VRRM, 50 A IFSM, and 10,000 V/μs dV/dt rating support robust switching in noisy environments.
Thermal performance is defined by RθJL = 24°C/W and RθJA = 70°C/W, enabling sustained 2 A conduction with minimal heatsinking. The device operates across –55°C to +150°C junction range and uses matte tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse voltage; sets upper limit for DC bus or flyback clamp voltage handling |
| IF | 2 A continuous - rated average forward current; defines steady-state power dissipation capability |
| VF @ 2 A, 25°C | 0.95 V - forward drop determines conduction loss and thermal load in high-duty-cycle applications |
| IR @ 150 V, 125°C | 5 mA - leakage current at max rated voltage and elevated temperature; critical for standby efficiency |
| IFSM | 50 A - non-repetitive surge current (8.3 ms half-sine); enables survival during load dump or inrush events |
| TJ max | +150°C - extended junction temperature rating supports under-hood automotive use without derating |
| dV/dt | 10,000 V/μs - critical rate-of-rise immunity prevents false turn-on in fast-switching topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY150-M3/5BT | Same 150 V VRRM, 2 A IF, but VF = 0.89 V @ 2 A, 25°C; RθJA = 65°C/W; AEC-Q101 qualified | Slightly lower conduction loss; tighter VF distribution; identical SMB package | Preferred where <5 mV VF reduction justifies alternate sourcing; same PCB layout |
| ON Semiconductor SB2150-T3 | 150 V VRRM, 2 A IF, VF = 0.92 V @ 2 A, 25°C; IR = 100 µA @ 25°C (vs. 100 µA for SS215H); not AEC-Q101 qualified | Lacks automotive qualification; higher room-temp leakage but comparable high-temp IR | Acceptable for industrial DC/DC where AEC-Q101 is not mandated; verify system-level reliability testing |
Compared with VS-2EY150-M3/5BT and SB2150-T3, the SS215H offers the highest junction temperature rating (+150°C vs. +125°C for SB2150-T3), guaranteed AEC-Q101 compliance, and lowest high-temperature leakage among the three at 125°C - making it optimal for under-hood automotive deployments requiring long-term thermal stability.

FAQ
What is the maximum junction temperature rating for the SS215H?
The SS215H has a maximum junction temperature rating of +150°C, verified per its absolute maximum ratings table. This allows uninterrupted operation in under-hood automotive environments where ambient temperatures exceed 105°C. The +150°C rating is confirmed in both the Absolute Maximum Ratings and Thermal Performance sections of the SS215H datasheet, distinguishing it from lower-voltage variants rated to +125°C.
Is the SS215H qualified to AEC-Q101 standards?
Yes, the SS215H is explicitly AEC-Q101 qualified, as stated in the FEATURES section of the official Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD, confirming suitability for automotive electronic control units and lighting modules where reliability is mission-critical.
What is the forward voltage of the SS215H at 2 A and 100°C junction temperature?
The SS215H exhibits a typical forward voltage of 0.80 V at 2 A and 100°C junction temperature, per the Electrical Specifications table. This value is lower than its 25°C VF (0.95 V), reflecting the negative temperature coefficient of Schottky diodes - a key design advantage for thermally demanding applications where conduction loss must remain stable across operating range.
Does the SS215H have a guard ring structure, and what is its purpose?
Yes, the SS215H incorporates a guard ring structure, explicitly listed in its FEATURES. This design enhances edge termination integrity, improving resistance to localized electric field crowding during over-voltage transients and increasing manufacturing yield consistency for the 150 V breakdown rating.
What is the moisture sensitivity level (MSL) of the SS215H, and how does it affect assembly?
The SS215H has a moisture sensitivity level of MSL 1, per J-STD-020. This means it can be stored indefinitely at ≤30°C/60% RH and subjected to standard reflow profiles (including lead-free) without prior baking - eliminating handling constraints and reducing SMT line downtime compared to MSL 3+ components.
